The United States has a long history of racial segregation, starting when the first European settlers came to North America. First through slavery, then through racist laws, and then through racist attitudes, African-American people in the United States have faced segregation for centuries. People of other races have been segregated too. For example, during World War II, the President of the United States, Franklin D. Roosevelt, ordered almost the entire Japanese-American population to be segregated in internment camps.
