of Congress established the Manzanar National Historic Site "to provide for the protection and interpretation of the historical, cultural, and natural resources associated with the relocation of Japanese Americans during World War II." Five years later, the National Park Service acquired of land at Manzanar from the City of Los Angeles. It was the first of the camps to be designated as a National Historical Site. After Congress named Manzanar a National Historic Site and gave the National Park Service the job of restoring the site in 1992, protests against its creation emerged.
