When has martial law been imposed in US history?

Martial law has been imposed in U.S. history during several notable events, including the Civil War when President Lincoln suspended habeas corpus, and during World War II when Japanese internment camps were established. Another significant instance occurred in Hawaii after the attack on Pearl Harbor in 1941, where martial law was declared and military rule was established. Additionally, local instances of martial law have occurred in response to civil disturbances, such as during the 1968 riots in Chicago.
