What year did Hawaii become a state?

Hawaii became a state on August 21, 1959. This event marked the culmination of a long process that began with the U.S. annexation of the islands in 1898, followed by Hawaii's designation as a territory in 1900. The path to statehood involved various legislative and public support efforts throughout the years, culminating in the approval of the Hawaii Admission Act by Congress in 1959. The significance of this date is not just that it marks Hawaii's admission into the Union, but it also reflects the broader context of the United States' expansion and the embrace of a diverse set of cultures and peoples within its state structure.

Other years listed in the choices do not correspond to Hawaii's admission into the United States as a state. The year 1950 predates significant statehood movements, while 1956 and 1962 are not significant milestones related to Hawaii's statehood. Thus, 1959 stands out as the only correct choice in this context.
