THIRTEEN years ago, researchers at the United States Holocaust Memorial Museum began the grim task of documenting all the ghettos, slave labor sites, concentration camps and killing factories that the Nazis set up throughout Europe.

What they have found so far has shocked even scholars steeped in the history of the Holocaust.

The researchers have cataloged some 42,500 Nazi ghettos and camps throughout Europe, spanning German-controlled areas from France to Russia and Germany itself, during Hitler's reign of brutality from 1933 to 1945.

The figure is so staggering that even fellow Holocaust scholars had to make sure they had heard it correctly when the lead researchers previewed their findings at an academic forum in late January at the German Historical Institute in Washington.

"The numbers are so much higher than what we originally thought," Hartmut Berghoff, director of the institute, said in an interview after learning of the new data.

"We knew before how horrible life in the camps and ghettos was," he said, "but the numbers are unbelievable."

The documented camps include not only "killing centers" but also thousands of forced labor camps, where prisoners manufactured war supplies; prisoner-of-war camps; sites euphemistically named "care" centers, where pregnant women were forced to have abortions or their babies were killed after birth; and brothels, where women were coerced into having sex with German military personnel.

Auschwitz and a handful of other concentration camps have come to symbolize the Nazi killing machine in the public consciousness. Likewise, the Nazi system for imprisoning Jewish families in hometown ghettos has become associated with a single site - the Warsaw Ghetto, famous for the 1943 uprising. But these sites, infamous though they are, represent only a minuscule fraction of the entire German network, the new research makes painfully clear.

The maps the researchers have created to identify the camps and ghettos turn wide sections of wartime Europe into black clusters of death, torture and slavery - centered in Germany and Poland, but reaching in all directions.

The lead editors on the project, Geoffrey Megargee and Martin Dean, estimate that 15 million to 20 million people died or were imprisoned in the sites that they have identified as part of a multivolume encyclopedia. (The Holocaust museum has published the first two, with five more planned by 2025.)

The existence of many individual camps and ghettos was previously known only on a fragmented, region-by-region basis. But the researchers, using data from some 400 contributors, have been documenting the entire scale for the first time, studying where they were located, how they were run, and what their purpose was.

The brutal experience of Henry Greenbaum, an 84-year-old Holocaust survivor who lives outside Washington, typifies the wide range of Nazi sites.

When Mr. Greenbaum, a volunteer at the Holocaust museum, tells visitors today about his wartime odyssey, listeners inevitably focus on his confinement of months at Auschwitz, the most notorious of all the camps.

But the images of the other camps where the Nazis imprisoned him are ingrained in his memory as deeply as the concentration camp number - A188991 - tattooed on his left forearm.

In an interview, he ticked off the locations in rapid fire, the details still vivid.

First came the Starachowice ghetto in his hometown in Poland, where the Germans herded his family and other local Jews in 1940, when he was just 12.

Next came a slave labor camp with six-foot-high fences outside the town, where he and a sister were moved while the rest of the family was sent to die at Treblinka. After his regular work shift at a factory, the Germans would force him and other prisoners to dig trenches that were used for dumping the bodies of victims. He was sent to Auschwitz, then removed to work at a chemical manufacturing plant in Poland known as Buna Monowitz, where he and some 50 other prisoners who had been held at the main camp at Auschwitz were taken to manufacture rubber and synthetic oil. And last was another slave labor camp at Flossenbürg, near the Czech border, where food was so scarce that the weight on his 5-foot-8-inch frame fell away to less than 100 pounds.

By the age of 17, Mr. Greenbaum had been enslaved in five camps in five years, and was on his way to a sixth, when American soldiers freed him in 1945. "Nobody even knows about these places," Mr. Greenbaum said. "Everything should be documented. That's very important. We try to tell the youngsters so that they know, and they'll remember."

The research could have legal implications as well by helping a small number of survivors document their continuing claims over unpaid insurance policies, looted property, seized land and other financial matters.

"HOW many claims have been rejected because the victims were in a camp that we didn't even know about?" asked Sam Dubbin, a Florida lawyer who represents a group of survivors who are seeking to bring claims against European insurance companies.

Dr. Megargee, the lead researcher, said the project was changing the understanding among Holocaust scholars of how the camps and ghettos evolved.

As early as 1933, at the start of Hitler's reign, the Third Reich established about 110 camps specifically designed to imprison some 10,000 political opponents and others, the researchers found. As Germany invaded and began occupying European neighbors, the use of camps and ghettos was expanded to confine and sometimes kill not only Jews but also homosexuals, Gypsies, Poles, Russians and many other ethnic groups in Eastern Europe. The camps and ghettos varied enormously in their mission, organization and size, depending on the Nazis' needs, the researchers have found.

The biggest site identified is the infamous Warsaw Ghetto, which held about 500,000 people at its height. But as few as a dozen prisoners worked at one of the smallest camps, the München-Schwabing site in Germany. Small groups of prisoners were sent there from the Dachau concentration camp under armed guard. They were reportedly whipped and ordered to do manual labor at the home of a fervent Nazi patron known as "Sister Pia," cleaning her house, tending her garden and even building children's toys for her.

When the research began in 2000, Dr. Megargee said he expected to find perhaps 7,000 Nazi camps and ghettos, based on postwar estimates. But the numbers kept climbing - first to 11,500, then 20,000, then 30,000, and now 42,500.

The numbers astound: 30,000 slave labor camps; 1,150 Jewish ghettos; 980 concentration camps; 1,000 prisoner-of-war camps; 500 brothels filled with sex slaves; and thousands of other camps used for euthanizing the elderly and infirm, performing forced abortions, "Germanizing" prisoners or transporting victims to killing centers.

In Berlin alone, researchers have documented some 3,000 camps and so-called Jew houses, while Hamburg held 1,300 sites.

Dr. Dean, a co-researcher, said the findings left no doubt in his mind that many German citizens, despite the frequent claims of ignorance after the war, must have known about the widespread existence of the Nazi camps at the time.

"You literally could not go anywhere in Germany without running into forced labor camps, P.O.W. camps, concentration camps," he said. "They were everywhere."

Historical Anti-Semitism

Anti-Semitism in Europe did not begin with Adolf Hitler. Though use of the term itself dates only to the 1870s, there is evidence of hostility toward Jews long before the Holocaust-even as far back as the ancient world, when Roman authorities destroyed the Jewish temple in Jerusalem and forced Jews to leave Palestine.

The Enlightenment, during the 17th and 18th centuries, emphasized religious tolerance, and in the 19th century Napoleon Bonaparte and other European rulers enacted legislation that ended long-standing restrictions on Jews. Anti-Semitic feeling endured, however, in many cases taking on a racial character rather than a religious one.

Did you know? Even in the early 21st century, the legacy of the Holocaust endures. Swiss government and banking institutions have in recent years acknowledged their complicity with the Nazis and established funds to aid Holocaust survivors and other victims of human rights abuses, genocide or other catastrophes.

Hitler's Rise to Power

The roots of Adolf Hitler's particularly virulent brand of anti-Semitism are unclear. Born in Austria in 1889, he served in the German army during World War I. Like many anti-Semites in Germany, he blamed the Jews for the country's defeat in 1918.

Soon after World War I ended, Hitler joined the National German Workers' Party, which became the National Socialist German Workers' Party (NSDAP), known to English speakers as the Nazis. While imprisoned for treason for his role in the Beer Hall Putsch of 1923, Hitler wrote the memoir and propaganda tract " Mein Kampf " (or "my struggle"), in which he predicted a general European war that would result in "the extermination of the Jewish race in Germany."

Hitler was obsessed with the idea of the superiority of the "pure" German race, which he called "Aryan," and with the need for "Lebensraum," or living space, for that race to expand. In the decade after he was released from prison, Hitler took advantage of the weakness of his rivals to enhance his party's status and rise from obscurity to power.

On January 30, 1933, he was named chancellor of Germany. After the death of President Paul von Hindenburg in 1934, Hitler anointed himself Fuhrer, becoming Germany's supreme ruler.

Concentration Camps

The twin goals of racial purity and territorial expansion were the core of Hitler's worldview, and from 1933 onward they would combine to form the driving force behind his foreign and domestic policy.

At first, the Nazis reserved their harshest persecution for political opponents such as Communists or Social Democrats. The first official concentration camp opened at Dachau (near Munich) in March 1933, and many of the first prisoners sent there were Communists.

Like the network of concentration camps that followed, becoming the killing grounds of the Holocaust, Dachau was under the control of Heinrich Himmler, head of the elite Nazi guard, the Schutzstaffel (SS) and later chief of the German police.

By July 1933, German concentration camps ( Konzentrationslager in German, or KZ) held some 27,000 people in "protective custody." Huge Nazi rallies and symbolic acts such as the public burning of books by Jews, Communists, liberals and foreigners helped drive home the desired message of party strength and unity.

In 1933, Jews in Germany numbered around 525,000-just one percent of the total German population. During the next six years, Nazis undertook an "Aryanization" of Germany, dismissing non-Aryans from civil service, liquidating Jewish-owned businesses and stripping Jewish lawyers and doctors of their clients.

Nuremberg Laws

Under the Nuremberg Laws of 1935, anyone with three or four Jewish grandparents was considered a Jew, while those with two Jewish grandparents were designated Mischlinge (half-breeds).

Under the Nuremberg Laws, Jews became routine targets for stigmatization and persecution. This culminated in Kristallnacht, or the "Night of Broken Glass" in November 1938, when German synagogues were burned and windows in Jewish home and shops were smashed; some 100 Jews were killed and thousands more arrested.

From 1933 to 1939, hundreds of thousands of Jews who were able to leave Germany did, while those who remained lived in a constant state of uncertainty and fear.

Euthanasia Program

In September 1939, Germany invaded the western half of Poland, starting World War II. German police soon forced tens of thousands of Polish Jews from their homes and into ghettoes, giving their confiscated properties to ethnic Germans (non-Jews outside Germany who identified as German), Germans from the Reich or Polish gentiles.

Surrounded by high walls and barbed wire, the Jewish ghettoes in Poland functioned like captive city-states, governed by Jewish Councils. In addition to widespread unemployment, poverty and hunger, overpopulation and poor sanitation made the ghettoes breeding grounds for disease such as typhus.

Meanwhile, beginning in the fall of 1939, Nazi officials selected around 70,000 Germans institutionalized for mental illness or physical disabilities to be gassed to death in the so-called Euthanasia Program.

After prominent German religious leaders protested, Hitler put an end to the program in August 1941, though killings of the disabled continued in secrecy, and by 1945 some 275,000 people deemed handicapped from all over Europe had been killed. In hindsight, it seems clear that the Euthanasia Program functioned as a pilot for the Holocaust.

'Final Solution'

Throughout the spring and summer of 1940, the German army expanded Hitler's empire in Europe, conquering Denmark, Norway, the Netherlands, Belgium, Luxembourg and France. Beginning in 1941, Jews from all over the continent, as well as hundreds of thousands of European Romani people, were transported to Polish ghettoes.

The German invasion of the Soviet Union in June 1941 marked a new level of brutality in warfare. Mobile killing units of Himmler's SS called Einsatzgruppen would murder more than 500,000 Soviet Jews and others (usually by shooting) over the course of the German occupation.

A memorandum dated July 31, 1941, from Hitler's top commander Hermann Goering to Reinhard Heydrich, chief of the SD (the security service of the SS), referred to the need for an Endlösung ( Final Solution) to "the Jewish question."

Yellow Stars

Beginning in September 1941, every person designated as a Jew in German-held territory was marked with a yellow, six-pointed star, making them open targets. Tens of thousands were soon being deported to the Polish ghettoes and German-occupied cities in the USSR.

Since June 1941, experiments with mass killing methods had been ongoing at the concentration camp of Auschwitz, near Krakow, Poland. That August, 500 officials gassed 500 Soviet POWs to death with the pesticide Zyklon-B. The SS soon placed a huge order for the gas with a German pest-control firm, an ominous indicator of the coming Holocaust.

Holocaust Death Camps

Beginning in late 1941, the Germans began mass transports from the ghettoes in Poland to the concentration camps, starting with those people viewed as the least useful: the sick, old and weak and the very young.

The first mass gassings began at the camp of Belzec, near Lublin, on March 17, 1942. Five more mass killing centers were built at camps in occupied Poland, including Chelmno, Sobibor, Treblinka, Majdanek and the largest of all, Auschwitz.

From 1942 to 1945, Jews were deported to the camps from all over Europe, including German-controlled territory as well as those countries allied with Germany. The heaviest deportations took place during the summer and fall of 1942, when more than 300,000 people were deported from the Warsaw ghetto alone.

Warsaw Ghetto Uprising

Amid the deportations, disease and constant hunger, incarcerated people in the Warsaw Ghetto rose up in armed revolt.

The Warsaw Ghetto Uprising from April 19-May 16, 1943, ended in the death of 7,000 Jews, with 50,000 survivors sent to extermination camps. But the resistance fighters had held off the Nazis for almost a month, and their revolt inspired revolts at camps and ghettos across German-occupied Europe.

Though the Nazis tried to keep operation of the camps secret, the scale of the killing made this virtually impossible. Eyewitnesses brought reports of Nazi atrocities in Poland to the Allied governments, who were harshly criticized after the war for their failure to respond, or to publicize news of the mass slaughter.

This lack of action was likely mostly due to the Allied focus on winning the war at hand, but was also partly a result of the general incomprehension with which news of the Holocaust was met and the denial and disbelief that such atrocities could be occurring on such a scale.

'Angel of Death'

At Auschwitz alone, more than 2 million people were murdered in a process resembling a large-scale industrial operation. A large population of Jewish and non-Jewish inmates worked in the labor camp there; though only Jews were gassed, thousands of others died of starvation or disease.

In 1943, eugenics advocate Josef Mengele arrived in Auschwitz to begin his infamous experiments on Jewish prisoners. His special area of focus was conducting medical experiments on twins, injecting them with everything from petrol to chloroform under the guise of giving them medical treatment. His actions earned him the nickname "the Angel of Death."

Nazi Rule Ends

By the spring of 1945, German leadership was dissolving amid internal dissent, with Goering and Himmler both seeking to distance themselves from Hitler and take power.

In his last will and political testament, dictated in a German bunker that April 29, Hitler blamed the war on "International Jewry and its helpers" and urged the German leaders and people to follow "the strict observance of the racial laws and with merciless resistance against the universal poisoners of all peoples"-the Jews.

The following day, Hitler died by suicide. Germany's formal surrender in World War II came barely a week later, on May 8, 1945.

German forces had begun evacuating many of the death camps in the fall of 1944, sending inmates under guard to march further from the advancing enemy's front line. These so-called "death marches" continued all the way up to the German surrender, resulting in the deaths of some 250,000 to 375,000 people.

In his classic book Survival in Auschwitz, the Italian-Jewish author Primo Levi described his own state of mind, as well as that of his fellow inmates in Auschwitz on the day before Soviet troops liberated the camp in January 1945: "We lay in a world of death and phantoms. The last trace of civilization had vanished around and inside us. The work of bestial degradation, begun by the victorious Germans, had been carried to conclusion by the Germans in defeat."

Legacy of the Holocaust

The wounds of the Holocaust-known in Hebrew as "Shoah," or catastrophe-were slow to heal. Survivors of the camps found it nearly impossible to return home, as in many cases they had lost their entire family and been denounced by their non-Jewish neighbors. As a result, the late 1940s saw an unprecedented number of refugees, POWs and other displaced populations moving across Europe.

In an effort to punish the villains of the Holocaust, the Allies held the Nuremberg Trials of 1945-46, which brought Nazi atrocities to horrifying light. Increasing pressure on the Allied powers to create a homeland for Jewish survivors of the Holocaust would lead to a mandate for the creation of Israel in 1948.

Over the decades that followed, ordinary Germans struggled with the Holocaust's bitter legacy, as survivors and the families of victims sought restitution of wealth and property confiscated during the Nazi years.

Beginning in 1953, the German government made payments to individual Jews and to the Jewish people as a way of acknowledging the German people's responsibility for the crimes committed in their name.
