Queen Liliuokalani was the last sovereign of the Kamehameha dynasty, which had ruled a unified Hawaiian kingdom since 1810. She was born on September 2, 1838 on the island of Oahu in Honolulu. Born as Lydia Kamakaeha, she became crown princess in 1877. As crown princess, she was thereafter known by her royal name, Liliuokalani. When she took throne in 1891, the monarchy's power were removed by American businessmen and landowners. When Liliuokalani acted to restore that power, U.S. military backup deposed her in 1893 and formed a provisional government. The United States annexed Hawaii in in 1898.
