DENVER, Colorado — The attack on Pearl Harbor came on December 7, 1941.
In the aftermath, President Franklin D. Roosevelt issued Executive Order 9066, which authorized the forced relocation of Japanese-Americans from the West Coast.
On August 27, 1942, some arrived at the Granada War Relocation Center in Southeastern Colorado as internees.
According to History Colorado, most came from California.
Their arrival signaled rising xenophobia throughout the United States.
The Granada War Relocation Center was one of 10 camps nationwide operated by the War Relocation Authority.
With a peak population of 7,318 people, Granada was the smallest of the camps.
They were detained based on their Japanese heritage alone.
Camp Amache, as it came to be known after a mishap with the post office in the nearby town of Granada, was known for its volunteerism.
Nearly 1,000 men and women volunteered or were drafted for World War II, more than any other camp in the country.
There is now a memorial to the 442 Regimental Combat Team on the grounds of the camp.
