History of racial segregation in the United States
In February 1942, President Franklin D. Roosevelt signed an order that allowed the military to force people to leave the West Coast.  However, Japanese-Americans were the only people on the West Coast who were forced to leave.  They were given 48 hours to leave their homes for internment camps.  These were camps where Japanese-Americans were kept separate from everybody else.  The camps were surrounded by barbed wire and guarded by soldiers with guns.
