During World War II, some people in America were afraid of Japanese people because Japan was an enemy of the United States. They thought the Japanese people living in America might hurt America. So, the government told all people of Japanese descent (people whose ancestors came from Japan) to move away from their homes and into special camps far away from where they lived. This is called internment.
Families had to leave their homes, schools, jobs, and everything they owned. They could only bring a few things with them. The camps were like little towns, but people weren't allowed to leave. There were guards and fences around the camps. The government said it was necessary to keep the Japanese Americans safe, but it was actually very unfair to them.
Many Japanese Americans felt sad, scared, and angry because they didn't do anything wrong. They were just like everyone else in America, but they were being treated differently because of their ancestry. They had to stay in the camps for several years until the war ended. After the war, they were allowed to leave the camps, but many of them lost their homes and businesses because they had been gone for so long.
Later, the government realized that what they did was very wrong, and they apologized to the Japanese Americans. They also gave them money to help them rebuild their lives. Today, we remember the internment of Japanese Americans as a sad time when people were not treated fairly just because of where their ancestors came from.
