Archduke Franz Ferdinand

Tensions had been brewing throughout Europe-especially in the troubled Balkan region of southeast Europe-for years before World War I actually broke out.

A number of alliances involving European powers, the Ottoman Empire, Russia and other parties had existed for years, but political instability in the Balkans (particularly Bosnia, Serbia and Herzegovina) threatened to destroy these agreements.

The spark that ignited World War I was struck in Sarajevo, Bosnia, where Archduke Franz Ferdinand -heir to the Austro-Hungarian Empire-was shot to death along with his wife, Sophie, by the Serbian nationalist Gavrilo Princip on June 28, 1914. Princip and other nationalists were struggling to end Austro-Hungarian rule over Bosnia and Herzegovina.

The assassination of Franz Ferdinand set off a rapidly escalating chain of events: Austria-Hungary, like many countries around the world, blamed the Serbian government for the attack and hoped to use the incident as justification for settling the question of Serbian nationalism once and for all.

Kaiser Wilhelm II

Because mighty Russia supported Serbia, Austria-Hungary waited to declare war until its leaders received assurance from German leader Kaiser Wilhelm II that Germany would support their cause. Austro-Hungarian leaders feared that a Russian intervention would involve Russia's ally, France, and possibly Great Britain as well.

On July 5, Kaiser Wilhelm secretly pledged his support, giving Austria-Hungary a so-called carte blanche, or "blank check" assurance of Germany's backing in the case of war. The Dual Monarchy of Austria-Hungary then sent an ultimatum to Serbia, with such harsh terms as to make it almost impossible to accept.

World War I Begins

Convinced that Austria-Hungary was readying for war, the Serbian government ordered the Serbian army to mobilize and appealed to Russia for assistance. On July 28, Austria-Hungary declared war on Serbia, and the tenuous peace between Europe's great powers quickly collapsed.

Within a week, Russia, Belgium, France, Great Britain and Serbia had lined up against Austria-Hungary and Germany, and World War I had begun.

The Western Front

According to an aggressive military strategy known as the Schlieffen Plan (named for its mastermind, German Field Marshal Alfred von Schlieffen), Germany began fighting World War I on two fronts, invading France through neutral Belgium in the west and confronting Russia in the east.

On August 4, 1914, German troops crossed the border into Belgium. In the first battle of World War I, the Germans assaulted the heavily fortified city of Liege, using the most powerful weapons in their arsenal-enormous siege cannons-to capture the city by August 15. The Germans left death and destruction in their wake as they advanced through Belgium toward France, shooting civilians and executing a Belgian priest they had accused of inciting civilian resistance.

First Battle of the Marne

In the First Battle of the Marne, fought from September 6-9, 1914, French and British forces confronted the invading German army, which had by then penetrated deep into northeastern France, within 30 miles of Paris. The Allied troops checked the German advance and mounted a successful counterattack, driving the Germans back to the north of the Aisne River.

The defeat meant the end of German plans for a quick victory in France. Both sides dug into trenches, and the Western Front was the setting for a hellish war of attrition that would last more than three years.

Particularly long and costly battles in this campaign were fought at Verdun (February-December 1916) and the Battle of the Somme (July-November 1916). German and French troops suffered close to a million casualties in the Battle of Verdun alone.

World War I Books and Art

The bloodshed on the battlefields of the Western Front, and the difficulties its soldiers had for years after the fighting had ended, inspired such works of art as " All Quiet on the Western Front" by Erich Maria Remarque and " In Flanders Fields"by Canadian doctor Lieutenant-Colonel John McCrae. In the latter poem, McCrae writes from the perspective of the fallen soldiers:

Published in 1915, the poem inspired the use of the poppy as a symbol of remembrance.

Visual artists like Otto Dix of Germany and British painters Wyndham Lewis, Paul Nash and David Bomberg used their firsthand experience as soldiers in World War I to create their art, capturing the anguish of trench warfare and exploring the themes of technology, violence and landscapes decimated by war.

The Eastern Front

On the Eastern Front of World War I, Russian forces invaded the German-held regions of East Prussia and Poland but were stopped short by German and Austrian forces at the Battle of Tannenberg in late August 1914.

Despite that victory, Russia's assault forced Germany to move two corps from the Western Front to the Eastern, contributing to the German loss in the Battle of the Marne.

Combined with the fierce Allied resistance in France, the ability of Russia's huge war machine to mobilize relatively quickly in the east ensured a longer, more grueling conflict instead of the quick victory Germany had hoped to win under the Schlieffen Plan.

Russian Revolution

From 1914 to 1916, Russia's army mounted several offensives on World War I's Eastern Front but was unable to break through German lines.

Defeat on the battlefield, combined with economic instability and the scarcity of food and other essentials, led to mounting discontent among the bulk of Russia's population, especially the poverty-stricken workers and peasants. This increased hostility was directed toward the imperial regime of Czar Nicholas II and his unpopular German-born wife, Alexandra.

Russia's simmering instability exploded in the Russian Revolution of 1917, spearheaded by Vladimir Lenin and the Bolsheviks, which ended czarist rule and brought a halt to Russian participation in World War I.

Russia reached an armistice with the Central Powers in early December 1917, freeing German troops to face the remaining Allies on the Western Front.

America Enters World War I

At the outbreak of fighting in 1914, the United States remained on the sidelines of World War I, adopting the policy of neutrality favored by President Woodrow Wilson while continuing to engage in commerce and shipping with European countries on both sides of the conflict.

Neutrality, however, it was increasingly difficult to maintain in the face of Germany's unchecked submarine aggression against neutral ships, including those carrying passengers. In 1915, Germany declared the waters surrounding the British Isles to be a war zone, and German U-boats sunk several commercial and passenger vessels, including some U.S. ships.

Widespread protest over the sinking by U-boat of the British ocean liner Lusitania-traveling from New York to Liverpool, England with hundreds of American passengers onboard-in May 1915 helped turn the tide of American public opinion against Germany. In February 1917, Congress passed a $250 million arms appropriations bill intended to make the United States ready for war.

Germany sunk four more U.S. merchant ships the following month, and on April 2 Woodrow Wilson appeared before Congress and called for a declaration of war against Germany.

Gallipoli Campaign

With World War I having effectively settled into a stalemate in Europe, the Allies attempted to score a victory against the Ottoman Empire, which entered the conflict on the side of the Central Powers in late 1914.

After a failed attack on the Dardanelles (the strait linking the Sea of Marmara with the Aegean Sea), Allied forces led by Britain launched a large-scale land invasion of the Gallipoli Peninsula in April 1915. The invasion also proved a dismal failure, and in January 1916 Allied forces staged a full retreat from the shores of the peninsula after suffering 250,000 casualties.

Did you know? The young Winston Churchill, then first lord of the British Admiralty, resigned his command after the failed Gallipoli campaign in 1916, accepting a commission with an infantry battalion in France.

British-led forces also combated the Ottoman Turks in Egypt and Mesopotamia, while in northern Italy, Austrian and Italian troops faced off in a series of 12 battles along the Isonzo River, located at the border between the two nations.

Battle of the Isonzo

The First Battle of the Isonzo took place in the late spring of 1915, soon after Italy's entrance into the war on the Allied side. In the Twelfth Battle of the Isonzo, also known as the Battle of Caporetto (October 1917), German reinforcements helped Austria-Hungary win a decisive victory.

After Caporetto, Italy's allies jumped in to offer increased assistance. British and French-and later, American-troops arrived in the region, and the Allies began to take back the Italian Front.

World War I at Sea

In the years before World War I, the superiority of Britain's Royal Navy was unchallenged by any other nation's fleet, but the Imperial German Navy had made substantial strides in closing the gap between the two naval powers. Germany's strength on the high seas was also aided by its lethal fleet of U-boat submarines.

After the Battle of Dogger Bank in January 1915, in which the British mounted a surprise attack on German ships in the North Sea, the German navy chose not to confront Britain's mighty Royal Navy in a major battle for more than a year, preferring to rest the bulk of its naval strategy on its U-boats.

The biggest naval engagement of World War I, the Battle of Jutland (May 1916) left British naval superiority on the North Sea intact, and Germany would make no further attempts to break an Allied naval blockade for the remainder of the war.

World War I Planes

World War I was the first major conflict to harness the power of planes. Though not as impactful as the British Royal Navy or Germany's U-boats, the use of planes in World War I presaged their later, pivotal role in military conflicts around the globe.

At the dawn of World War I, aviation was a relatively new field; the Wright brothers took their first sustained flight just eleven years before, in 1903. Aircraft were initially used primarily for reconnaissance missions. During the First Battle of the Marne, information passed from pilots allowed the allies to exploit weak spots in the German lines, helping the Allies to push Germany out of France.

The first machine guns were successfully mounted on planes in June of 1912 in the United States, but were imperfect; if timed incorrectly, a bullet could easily destroy the propeller of the plane it came from. The Morane-Saulnier L, a French plane, provided a solution: The propeller was armored with deflector wedges that prevented bullets from hitting it. The Morane-Saulnier Type L was used by the French, the British Royal Flying Corps (part of the Army), the British Royal Navy Air Service and the Imperial Russian Air Service. The British Bristol Type 22 was another popular model used for both reconnaissance work and as a fighter plane.

Dutch inventor Anthony Fokker improved upon the French deflector system in 1915. His "interrupter" synchronized the firing of the guns with the plane's propeller to avoid collisions. Though his most popular plane during WWI was the single-seat Fokker Eindecker, Fokker created over 40 kinds of airplanes for the Germans.

The Allies debuted the Handley-Page HP O/400, the first two-engine bomber, in 1915. As aerial technology progressed, long-range heavy bombers like Germany's Gotha G.V. (first introduced in 1917) were used to strike cities like London. Their speed and maneuverability proved to be far deadlier than Germany's earlier Zeppelin raids.

By the war's end, the Allies were producing five times more aircraft than the Germans. On April 1, 1918, the British created the Royal Air Force, or RAF, the first air force to be a separate military branch independent from the navy or army.

Second Battle of the Marne

With Germany able to build up its strength on the Western Front after the armistice with Russia, Allied troops struggled to hold off another German offensive until promised reinforcements from the United States were able to arrive.

On July 15, 1918, German troops launched what would become the last German offensive of the war, attacking French forces (joined by 85,000 American troops as well as some of the British Expeditionary Force) in the Second Battle of the Marne. The Allies successfully pushed back the German offensive and launched their own counteroffensive just three days later.

After suffering massive casualties, Germany was forced to call off a planned offensive further north, in the Flanders region stretching between France and Belgium, which was envisioned as Germany's best hope of victory.

The Second Battle of the Marne turned the tide of war decisively towards the Allies, who were able to regain much of France and Belgium in the months that followed.

The Harlem Hellfighters and Other All-Black Regiments

By the time World War I began, there were four all-Black regiments in the U.S. military: the 24th and 25th Infantry and the 9th and 10th Cavalry. All four regiments comprised of celebrated soldiers who fought in the Spanish-American War and American-Indian Wars, and served in the American territories. But they were not deployed for overseas combat in World War I.

Blacks serving alongside white soldiers on the front lines in Europe was inconceivable to the U.S. military. Instead, the first African American troops sent overseas served in segregated labor battalions, restricted to menial roles in the Army and Navy, and shutout of the Marines, entirely. Their duties mostly included unloading ships, transporting materials from train depots, bases and ports, digging trenches, cooking and maintenance, removing barbed wire and inoperable equipment, and burying soldiers.

Facing criticism from the Black community and civil rights organizations for its quotas and treatment of African American soldiers in the war effort, the military formed two Black combat units in 1917, the 92nd and 93rd Divisions. Trained separately and inadequately in the United States, the divisions fared differently in the war. The 92nd faced criticism for their performance in the Meuse-Argonne campaign in September 1918. The 93rd Division, however, had more success.

With dwindling armies, France asked America for reinforcements, and General John Pershing, commander of the American Expeditionary Forces, sent regiments in the 93 Division to over, since France had experience fighting alongside Black soldiers from their Senegalese French Colonial army. The 93 Division's 369 regiment, nicknamed the Harlem Hellfighters, fought so gallantly, with a total of 191 days on the front lines, longer than any AEF regiment, that France awarded them the Croix de Guerre for their heroism. More than 350,000 African American soldiers would serve in World War I in various capacities.

Toward Armistice

By the fall of 1918, the Central Powers were unraveling on all fronts.

Despite the Turkish victory at Gallipoli, later defeats by invading forces and an Arab revolt that destroyed the Ottoman economy and devastated its land, and the Turks signed a treaty with the Allies in late October 1918.

Austria-Hungary, dissolving from within due to growing nationalist movements among its diverse population, reached an armistice on November 4. Facing dwindling resources on the battlefield, discontent on the homefront and the surrender of its allies, Germany was finally forced to seek an armistice on November 11, 1918, ending World War I.

Treaty of Versailles

At the Paris Peace Conference in 1919, Allied leaders stated their desire to build a post-war world that would safeguard itself against future conflicts of such a devastating scale.

Some hopeful participants had even begun calling World War I "the War to End All Wars." But the Treaty of Versailles, signed on June 28, 1919, would not achieve that lofty goal.

Saddled with war guilt, heavy reparations and denied entrance into the League of Nations, Germany felt tricked into signing the treaty, having believed any peace would be a "peace without victory," as put forward by President Wilson in his famous Fourteen Points speech of January 1918.

As the years passed, hatred of the Versailles treaty and its authors settled into a smoldering resentment in Germany that would, two decades later, be counted among the causes of World War II.

World War I Casualties

World War I took the lives of more than 9 million soldiers; 21 million more were wounded. Civilian casualties numbered close to 10 million. The two nations most affected were Germany and France, each of which sent some 80 percent of their male populations between the ages of 15 and 49 into battle.

The political disruption surrounding World War I also contributed to the fall of four venerable imperial dynasties: Germany, Austria-Hungary, Russia and Turkey.

Legacy of World War I

World War I brought about massive social upheaval, as millions of women entered the workforce to replace men who went to war and those who never came back. The first global war also helped to spread one of the world's deadliest global pandemics, the Spanish flu epidemic of 1918, which killed an estimated 20 to 50 million people.

World War I has also been referred to as "the first modern war." Many of the technologies now associated with military conflict-machine guns, tanks, aerial combat and radio communications-were introduced on a massive scale during World War I.

The severe effects that chemical weapons such as mustard gas and phosgene had on soldiers and civilians during World War I galvanized public and military attitudes against their continued use. The Geneva Convention agreements, signed in 1925, restricted the use of chemical and biological agents in warfare and remain in effect today.

World War II, conflict that involved virtually every part of the world during the years 1939-45. The principal belligerents were the Axis powers- Germany, Italy, and Japan-and the Allies- France, Great Britain, the United States, the Soviet Union, and, to a lesser extent, China. The war was in many respects a continuation, after an uneasy 20-year hiatus, of the disputes left unsettled by World War I. The 40,000,000-50,000,000 deaths incurred in World War II make it the bloodiest conflict, as well as the largest war, in history.

Along with World War I, World War II was one of the great watersheds of 20th-century geopolitical history. It resulted in the extension of the Soviet Union's power to nations of eastern Europe, enabled a communist movement to eventually achieve power in China, and marked the decisive shift of power in the world away from the states of western Europe and toward the United States and the Soviet Union.

Axis initiative and Allied reaction

The outbreak of war

By the early part of 1939 the German dictator Adolf Hitler had become determined to invade and occupy Poland. Poland, for its part, had guarantees of French and British military support should it be attacked by Germany. Hitler intended to invade Poland anyway, but first he had to neutralize the possibility that the Soviet Union would resist the invasion of its western neighbour. Secret negotiations led on August 23-24 to the signing of the German-Soviet Nonaggression Pact in Moscow. In a secret protocol of this pact, the Germans and the Soviets agreed that Poland should be divided between them, with the western third of the country going to Germany and the eastern two-thirds being taken over by the U.S.S.R.

Having achieved this cynical agreement, the other provisions of which stupefied Europe even without divulgence of the secret protocol, Hitler thought that Germany could attack Poland with no danger of Soviet or British intervention and gave orders for the invasion to start on August 26. News of the signing, on August 25, of a formal treaty of mutual assistance between Great Britain and Poland (to supersede a previous though temporary agreement) caused him to postpone the start of hostilities for a few days. He was still determined, however, to ignore the diplomatic efforts of the western powers to restrain him. Finally, at 12:40 pm on August 31, 1939, Hitler ordered hostilities against Poland to start at 4:45 the next morning. The invasion began as ordered. In response, Great Britain and France declared war on Germany on September 3, at 11:00 am and at 5:00 pm, respectively. World War II had begun.

Flappers: The 'New Woman'

Perhaps the most familiar symbol of the "Roaring Twenties" is probably the flapper: a young woman with bobbed hair and short skirts who drank, smoked and said "unladylike" things, in addition to being more sexually "free" than previous generations. In reality, most young women in the 1920s did none of these things (though many did adopt a fashionable flapper wardrobe), but even those women who were not flappers gained some unprecedented freedoms.

They could vote at last: The 19th Amendment to the Constitution had guaranteed that right in 1920, though it would be decades before Black women in the South could fully exercise their right to vote without Jim Crow segregation laws.

Millions of women worked in blue-collar jobs, as well as white-collar jobs (as stenographers, for example) and could afford to participate in the burgeoning consumer economy. The increased availability of birth-control devices such as the diaphragm made it possible for women to have fewer children.

In 1912, an estimated 16 percent of American households had electricity; by the mid-1920s, more than 60 percent did. And with this electrification came new machines and technologies like the washing machine, the freezer and the vacuum cleaner eliminated some of the drudgeries of household work.

Did you know? Because the 18th Amendment and the Volstead Act did not make it illegal to drink alcohol, only to manufacture and sell it, many people stockpiled liquor before the ban went into effect. Rumor had it that the Yale Club in New York City had a 14-year supply of booze in its basement.

Fashion, Fads and Film Stars

During the 1920s, many Americans had extra money to spend-and spend it they did, on movies, fashion and consumer goods such as ready-to-wear clothing and home appliances like electric refrigerators. In particular, they bought radios.

The first commercial radio station in the United States, Pittsburgh's KDKA, hit the airwaves in 1920. Two years later Warren G. Harding became the first president to address the nation by radio -and three years later there were more than 500 stations in the nation. By the end of the 1920s, there were radios in more than 12 million households.

People also swarmed to see Hollywood movies: Historians estimate that, by the end of the decades, three-quarters of the American population visited a movie theater every week, and actors like Charlie Chaplin, Gloria Swanson, Rudolph Valentino and Tallulah Bankhead became household names.

But the most important consumer product of the 1920s was the automobile. Low prices (the Ford Model T cost just $260 in 1924) and generous credit made cars affordable luxuries at the beginning of the decade; by the end, they were practically necessities.

By 1929 there was one car on the road for every five Americans. Meanwhile, an economy of automobiles was born: Businesses like service stations and motels sprang up to meet drivers' needs-as did the burgeoning oil industry.

The Jazz Age

Cars also gave young people the freedom to go where they pleased and do what they wanted. (Some pundits called them "bedrooms on wheels.") What many young people wanted to do was dance: the Charleston, the cake walk, the black bottom and the flea hop were popular dances of the era.

Jazz bands played at venues like the Savoy and the Cotton Club in New York City and the Aragon in Chicago; radio stations and phonograph records (100 million of which were sold in 1927 alone) carried their tunes to listeners across the nation. Some older people objected to jazz music's "vulgarity" and "depravity" (and the "moral disasters" it supposedly inspired), but many in the younger generation loved the freedom they felt on the dance floor.

The novels of F. Scott Fitzgerald chronicled the hedonism and excitement of the Jazz Age-Fitzgerald once claimed that the 1920s were "the most expensive orgy in history"-while other writers, artists, musicians and designers ushered in a new era of experimental Art Deco and modernist creativity.

Prohibition Era

During the 1920s, some freedoms were expanded while others were curtailed. The 18th Amendment to the Constitution, ratified in 1919, had banned the manufacture and sale of "intoxicating liquors," and at 12 a.m. on January 16, 1920, the federal Volstead Act closed every tavern, bar and saloon in the United States. From then on, it was illegal to sell any "intoxication beverages" with more than 0.5 percent alcohol.

This drove the liquor trade underground-now, instead of ordinary bars, people simply went to nominally illegal speakeasies, where liquor was controlled by bootleggers, racketeers and other organized crime figures such as Chicago gangster Al Capone. (Capone reportedly had 1,000 gunmen and half of Chicago's police force on his payroll.)

To many middle-class white Americans, Prohibition was a way to assert some control over the unruly immigrant masses who crowded the nation's cities. For instance, to the so-called "Drys," beer was known as "Kaiser brew." Drinking was a symbol of all they disliked about the modern city, and eliminating alcohol would, they believed, turn back the clock to an earlier and more comfortable time

Immigration and Racism in the 1920s

Prohibition was not the only source of social tension during the 1920s. An anti- Communist "Red Scare" in 1919 and 1920 encouraged a widespread nativist and anti-immigrant hysteria. This led to the passage of an extremely restrictive immigration law, the National Origins Act of 1924, which set immigration quotas that excluded some people (Eastern Europeans and Asians) in favor of others (Northern Europeans and people from Great Britain, for example).

Immigrants were hardly the only targets in this decade. The Great Migration of Black Americans from the rural South to Northern cities and the increasing visibility of Black culture-jazz and blues music, for example, and the literary movement known as the Harlem Renaissance-discomfited some white Americans. Millions of people, not just in the South but across the country, joined the Ku Klux Klan in the 1920s.

By the middle of the decade, the KKK had two million members, many of whom believed the Klan represented a return to all the "values" that the fast-paced, city-slicker Roaring Twenties were trampling. More specifically, the 1920s represented economic and political uplift for Black Americans that threatened the social hierarchy of Jim Crow oppression.

Early Civil Rights Activism

During this decade, Black Americans sought stable employment, better living conditions and political participation. Many who migrated to the North found jobs in the automobile, steel, shipbuilding and meatpacking industries. But with more work came more exploitation.

In 1925, civil rights activist A. Philip Randolph founded the first predominantly Black labor union, the Brotherhood of Sleeping Car Porters, to draw attention to the discriminatory hiring practices and working conditions for Blacks. And as housing demands increased for Black people in the North, so did discriminatory housing practices that led to a rise of urban ghettos, where Black Americans-excluded from white neighborhoods-were relegated to inadequate, overcrowded and unsanitary living conditions.

Black Americans battled for political and civil rights throughout the Roaring Twenties and beyond. The NAACP launched investigations into Black disenfranchisement in the 1920 presidential election, as well as surges of white mob violence, such as the Tulsa Race Massacre of 1921.

The NAACP also pushed for the passage of the Dyer Anti-Lynching Bill, a law to make lynching a federal crime, but it was defeated by a Senate filibuster in 1922. A political milestone for Black Americans finally occurred when Oscar De Priest, a Chicago Republican, became the first Black congressman since Reconstruction to be elected to the House of Representatives in 1928.

The Roaring Twenties ushered in several demographic shifts, or what one historian called a "cultural Civil War" between city-dwellers and small-town residents, Protestants and Catholics, Blacks and whites, "New Women" and advocates of old-fashioned family values.

But coming immediately after the hardships of World War I and the Spanish flu epidemic, the Roaring Twenties also gave many middle-class Americans an unprecedented taste of freedom, unbridled fun and upward economic mobility unsurpassed in U.S. history.

The nations of Europe were at war soon after the assassination of Archduke Franz Ferdinand of Austria-Hungary. The First World War was fought from 1914 to 1918. More than 650,000 Canadians and Newfoundlanders served in this war, then called The Great War. More than 66,000 of our service members gave their lives and more than 172,000 were wounded. Their contributions and sacrifices earned Canada a separate signature on the Treaty of Versailles. This Treaty formally ended the war. These wartime efforts helped Canada gain new respect on the international stage as an independent country.

When Union Army General William Tecumseh Sherman famously said "War is hell," he was referring to war in general, but he could have been describing trench warfare, a military tactic that's been traced to the Civil War. Trenches-long, deep ditches dug as protective defenses-are most often associated with World War I, and the results of trench warfare in that conflict were hellish indeed.

Trenches were common throughout the Western Front.

Trench warfare in World War I was employed primarily on the Western Front, an area of northern France and Belgium that saw combat between German troops and Allied forces from France, Great Britain and, later, the United States.

Although trenches were hardly new to combat: Prior to the advent of firearms and artillery, they were used as defenses against attack, such as moats surrounding castles. But they became a fundamental part of the strategy with the influx of modern weapons of war.

Long, narrow trenches dug into the ground at the front, usually by the infantry soldiers who would occupy them for weeks at a time, were designed to protect World War I troops from machine-gun fire and artillery attacks from the air.

As the "Great War" also saw the wide use of chemical warfare and poison gas, the trenches were thought to offer some degree of protection against exposure. (While significant exposure to militarized chemicals such as mustard gas would result in almost certain death, many of the gases used in World War I were still relatively weak.)

Thus, trenches may have afforded some protection by allowing soldiers more time to take other defensive steps, such as putting on gas masks.

Trench warfare caused enormous numbers of casualties.

At least initially in World War I, forces mounted attacks from the trenches, with bayonets fixed to their rifles, by climbing over the top edge into what was known as "no man's land," the area between opposing forces, usually in a single, straight line and under a barrage of gunfire.

Not surprisingly, this approach was rarely effective and often led to mass casualties.

Later in the war, forces began mounting attacks from the trenches at night, usually with the support of covering artillery fire. The Germans soon became known for effectively mounting nighttime incursions behind enemy lines, by sending highly trained soldiers to attack the trenches of opposing forces at what they perceived as weak points.

If successful, these soldiers would breach enemy lines and circle around to attack their opponents from the rear, while their comrades would mount a traditional offensive at the front.

The brutality of trench warfare is perhaps best typified by the 1916 Battle of the Somme in France. British troops suffered 60,000 casualties on the first day of fighting alone.

Disease and 'shell shock' were rampant in the trenches.

With soldiers fighting in close proximity in the trenches, usually in unsanitary conditions, infectious diseases such as dysentery, cholera and typhoid fever were common and spread rapidly.

Constant exposure to wetness caused trench foot, a painful condition in which dead tissue spread across one or both feet, sometimes requiring amputation. Trench mouth, a type of gum infection, was also problematic and is thought to be associated with the stress of nonstop bombardment.

As they were often effectively trapped in the trenches for long periods of time, under nearly constant bombardment, many soldiers suffered from " shell shock," the debilitating mental illness known today as post-traumatic stress disorder (PTSD).

It's likely all of these factors, which stemmed from the widespread use of trench warfare, made World War I the deadliest conflict in global history to that point. It's believed that as many as one in 10 of all fighting forces in the conflict were killed.

It was also the first conflict in world history to have more deaths caused by combat, rather than from disease spread during the fighting.

Trench warfare was also employed in World War II and in the Korean War to some degree, but it has not been used regularly during conflicts in the ensuing decades.

My brother joined for the first time, joining more than a million other brave Canadians who did so in order to defend their families and uphold their names. My mother was upset when she heard that her son and husband were now both fighting in the war. I was quite worried about losing my father, with whom I had shared my whole life, and my brother.

The Battle of Hong Kong caused unspeakable suffering for our family. My mother sadly committed herself as a result of the heartbreaking blow that was the death of my father. In the meantime, my brother was fighting the Japanese soldiers in the war with a fierce commitment. But he hinted that he might not be able to come back in a letter he wrote to me. My sisters and I were devastated by the news. With their brisk and persistent strikes, the Japanese had won the battle and left a path of devastation in their wake. My brother endured a grimmer fate during the conflict. The Japanese took him prisoner of war and imprisoned him. My brother was made to work against his will and was made to live a slave's existence in mines and shipyards. He worked long hours in the cold and was given pitiful food that almost kept him alive. The difficult circumstances and ongoing struggles served as a continual reminder of the savagery his Japanese captors had visited upon him and many others. The terrifying events that occurred during the Battle of Hong Kong made a lasting impression on our family and will always be remembered as a monument to our family's fortitude and bravery in the face of unspeakable evil.

Jazz's throbbing rhythms, speakeasies, and the flowing attraction of booze defined the lively age of the 1920s. My parents would go out into the night with a secret password in order to enter these private institutions. Flappers, fearless women who embraced sexual independence and partied the night away in jazz clubs concealed inside the speakeasies, were everywhere. The era's economic progress and the significant contributions of African-Canadians to the fields of music and literature, which instilled a sense of freedom and hope in people's hearts, should be credited for jazz's increasing popularity at this period. An abundance of new consumer items, including electric toasters, irons, sewing machines, cosmetics, and trendy bathing suits and clothing, flooded the market as Canadian cities saw an increase in population.

My mother Deborah William Henry relentlessly worked to advance women's suffrage in the 1910s. She and her companions had through a great deal of suffering as suffragettes, including violent police beatings, mocking looks from neighbors, and even being kicked out of their houses by their husbands due to their participation in demonstrations. Strong suffragette Deborah William Henry, my mother met so much hostility that my father violently opposed her, forcing her to leave our house. My father was thus left in charge of taking care of my siblings and I. My mother confided in me that she and her friends engaged in telegraph line disruptions, hunger strikes, and enthusiastic song performances, with some of them even pledging to make the ultimate sacrifice. Women in Canada won the right to vote in 1919 thanks to their unimaginable sacrifices, opening the door for subsequent generations of women to enjoy equal rights and benefiting from improvements in work, healthcare, education, and the elimination of violence against women.

My father, Heswick William Henry described to us his horrific experiences while serving in the trenches. Many troops suffered from trench foot, mouth, and fever as a result of inadequate hygiene, severe forms of gingivitis, and lice. Rodents, figs, and slugs were identified as additional pests in the trenches. They were apparently always anxious due to the continual threat of death, their incredibly small living spaces, and their lack of sleep. They apparently suffered harm to their health and vitality as well. My father described the unfathomable atrocities he faced while living in the trenches in his horrifying memoirs. Due to the appalling circumstances, which included poor cleanliness, widespread gingivitis, and lice infestations, many people had illnesses including trench foot, mouth ulcers, and recurrent fevers. Rodents, maggots, and slugs were just a few of the pests that made an already precarious situation worse. Their existence was characterized by claustrophobic living conditions, continual worry, and a persistent lack of sleep. Their health and vigor were negatively impacted by the constant stress, leaving them visibly worn out.

My father, Heswick William Henry, enthusiastically accepted an impractical perspective on the war in 1914 and enlisted in the British military. He excitedly aspired to join the army, seeing it as a chance to honor himself and his family, driven by a romanticized picture of the fight. His resolve to fight against Germany was deeply rooted in patriotism, and this served as a major driving force for his enlistment.
