Darren - May 22, 2025

During World War II, following the attack on Pearl Harbor, fear and suspicion against Japanese Americans surged. President Franklin D. Roosevelt issued Executive Order 9066 in 1942, which led to the forced relocation and internment of approximately 120,000 individuals of Japanese descent. Most were American citizens. This controversial decision was driven by the mistaken belief that Japanese Americans posed a security threat. The internment camps represented a significant, albeit dark, chapter in U.S. history, highlighting the tension between national security and civil liberties. Understanding this context is crucial as we delve deeper into lesser-known facts about these camps.

There were a total of ten internment camps established across the United States, primarily located in remote areas. These camps were spread across states such as California, Arizona, Utah, Colorado, Idaho, Wyoming, and Arkansas.

3. Population Affected

The internment affected approximately 120,000 individuals, the majority of whom were Japanese Americans. Of these, about two-thirds were U.S. citizens by birth, while the remaining third were Japanese nationals who were barred from naturalization. The internment targeted people living primarily along the West Coast, uprooting entire communities and disrupting their lives.
