'Iolani Palace is a living restoration of the official royal residence of the Kalakaua Dynasty, which ruled the Kingdom of Hawai'i from 1874 to 1893. King Kalakaua, who reigned for 17 years, built the palace in 1882 as a symbol of Hawaii's civilized and enlightened leaders as well as its sovereignty. His sister and successor, Queen Lili'uokalani, ruled for two years before a provisional government deposed her on January 17, 1893. She was later imprisoned in the palace for eight months in 1895 by the Republic of Hawai'i. In 1962, 'Iolani Palace was designated a National Historic Landmark, and in 1978 it reopened for public tours after a monumental nine-year restoration project.
