From the plaque:
In the early part of World
War II, 110,000 persons of Japanese ancestry were interned
in relocation centers by Executive Order No. 9066 issued
February 19, 1942. Manzanar, the first of ten such concentration
camps, was bounded by barbed wire and guard towers. It
confined ten thousand persons, the majority of them American
citizens. May the injustices and humiliation suffered
here as a result of hysteria, racism, and economic exploitation
never emerge again.
Plaque placed by the State Department of Parks and Recreation in cooperation with the Manzanar Committee and the Japanese American Citizens League, April 14, 1973.
