Background

The Merced Assembly Center, located at 37.2914°N 120.4850°W / 37.2914; -120.4850 in Merced, California, was one of sixteen temporary assembly centers hastily constructed in the wake of Executive Order 9066 to incarcerate those of Japanese ancestry beginning in the spring of 1942, following the attack on Pearl Harbor and prior to the construction of more permanent concentration camps to house those forcibly removed from the West Coast. The Merced Assembly Center was located at the Merced County Fairgrounds and operated for 133 days, from May 6, 1942 to September 15, 1942, with a peak population of 4,508. 4,669 Japanese Americans were ultimately incarcerated at the Merced Assembly Center.
