Final answer:
The forced relocation and internment of around 120,000 individuals of Japanese ancestry, mainly U.S. citizens, was ordered by President Roosevelt after the 1941 attack on Pearl Harbor, leading to the unjust loss of civil liberties and significant hardships.
Step-by-step explanation:
Following the attack on Pearl Harbor in December 1941, a significant and somber episode in United States history unfolded as President Franklin D. Roosevelt signed Executive Order 9066. This order facilitated the forced relocation and internment of around 120,000 individuals of Japanese ancestry, the majority of whom were American citizens, to relocation camps during World War II.
These actions were largely motivated by unfounded fears of espionage and sabotage, and they stripped Japanese Americans of their civil liberties, resulting in loss of property and the establishment of internment camps across the West United States.
Despite no evidence of disloyalty, Japanese Americans faced harsh living conditions and discrimination, while some still demonstrated their loyalty by serving in the U.S. military during the war. It was not until the 1980s and 1990s that the U.S government revisited these injustices, leading to formal apologies and reparation efforts.
