African Americans were often looked at as second class citizens. When American troops realized that 126,000 people were not enough they came up with the Selective Service Act. When the U.S. entered the war against Europe, blacks were still being turned away. When WWI finally broke out there were four all black regiments. Many blacks were volunteering but the “African Americans” were filled.

The Spanish Influenza lasted from 1918-1920. The Spanish Influenza impacted America’s ability to build a military because when traveling from camp to camp the virus traveled with them. September through November the flu and pneumonia hit 20%-40% of all Army and Navy troops. High infection rates resulted in training schedules and induction.

No one is 100% certain how the American troops got the nickname “doughboys.” There were several theories. For example during the Mexican War in 1846 some believed that when walking along dusty terrain it looked like flour or dough later giving them the name “doughboys.” Another theory was by Paul Dickson, in his book “War Slang” he stated that they used clay to keep the piping on their uniforms white. So when it rained it turned into “doughy blobs” which gave them the name “doughboys.”

This law was signed on May 18, 1917 by President Woodrow Wilson. The Selective Service Act was where any man between the ages of 21 and 30 were required to be a part of the military service. 10 million men were registered in just a few short months. Men registering helped the military by building their numbers up giving them more of an advantage.
