Which Supreme Court case upheld the internment of Japanese Americans?

The Supreme Court case that upheld the internment of Japanese Americans during World War II is Korematsu v. United States. This landmark decision, delivered in 1944, addressed the constitutionality of the wartime internment camps established following the attack on Pearl Harbor. The Court ruled that the government's decision to intern Japanese Americans was a legitimate exercise of wartime powers and was justified by the perceived military necessity at the time, despite the significant violation of civil liberties it represented.

This case is historically significant as it reflects how fear and prejudice can lead to the infringement of individual rights, particularly during times of national crisis. The decision has been widely criticized in later years for its failure to uphold the principles of justice and equality for all citizens, leading to important discussions about civil rights and governmental authority. Subsequent reflections and interpretations, including dissents from justices at the time, have underscored the lesson about protecting minority rights against majority power during emergencies.
