The Pearl Harbor attack intensified existing hostility towards Japanese Americans. As wartime hysteria mounted, President Roosevelt signed Executive Order 9066 forcing over 120,000 West Coast persons of Japanese ancestry (Nikkei) to leave their homes, jobs, and lives behind, forcing them into one of ten prison camps spread across the nation because of their ethnicity. This is Minidoka's story.
