Hawaii Becomes a State. August 21, 1959. The U.S. had built a naval base in Hawaii at Pearl Harbor. Hawaii's importance as a military outpost became critical when Japan attacked Pearl Harbor on December 7, 1941. This brought the United States as well as Hawaii into World War II.
In 1959, the United States added two more states to the Union: Alaska and Hawaii, the non-contiguous states. Alaska was admitted to the Union on January 3, 1959, becoming the 49th state, and Hawaii joined on August 21, 1959, becoming the 50th state.
