Hawaii became the 50th state of the United States on August 21, 1959. This followed a long process that began with its annexation in 1898 and continued through its status as a U.S. territory. The push for statehood gained momentum after World War II, as many residents sought equal rights and representation. The statehood vote was held in June 1959, where over 90% of voters supported joining the Union. President Dwight D. Eisenhower signed the statehood bill, officially making Hawaii a state. This event marked a significant moment in U.S. history, expanding the nation’s reach into the Pacific.
