Hawaii was first discovered by Polynesian settlers who arrived by double-hulled canoe. They farmed the land and set up communities called Ahupua’a, which extended from the mountains to the ocean in order to use the natural resources of the island in a sustainable manner. In 1810, the kingdom of Hawaii was formed under the rule of King Kamehameha, who united the eight Hawaiian islands by defeating island chiefs. The Hawaiian monarchy ruled until 1893, when white plantation owners, the descendants of missionaries, overthrew Queen Lili’uokalani and forced her to sign over the kingdom. Hawaii then became a territory of the United States and was granted statehood on August 21, 1959. This historic date is celebrated every year in Hawaii as a state holiday, Admissions Day.
