Hawaii, the fiftieth state of the United States, was admitted to the Union on August 21, 1959. Located in the central Pacific Ocean, it is the only U.S. state made up entirely of islands and the only one outside North America. Hawaii has a rich cultural heritage rooted in Native Hawaiian traditions and was once an independent kingdom before being annexed by the United States in 1898. Known for its stunning natural beauty, volcanic landscapes, and unique biodiversity, Hawaii plays a vital role in tourism, military defense, and Pacific relations. Its capital is Honolulu, located on the island of O'ahu.
