Among its many unique distinctions, Hawaii is the only U.S. state that contains an actual palace that royalty once lived in. Until Americans overthrew it in 1893, Hawaii was an independent kingdom, led by generations of native islanders. The National Museum of the American Indian’s latest exhibit explains to residents unfamiliar with this particular example of imperialism just what the archipelago looked like under the command of King Kamehameha and Queen Lili’uokalani. From the sugar industry, which greedy businessmen were eager to take control of, to native cultural traditions that fell out of favor or were appropriated by others, visitors will learn seldom-told stories from the 50th state. The whole endeavor is meant to be as faithful to Hawaiian history as possible (curators consulted scholars, community members, and political leaders while preparing it), so if you’re looking to pick up a cone of Dole Whip in the cafeteria on the way out, you’ll be disappointed. The exhibition is on view daily, 10 a.m. to 5:30 p.m., at the National Museum of the American Indian, 4th Street and Independence Ave. NW. Free. (202) 633-1000. nmai.si.edu.
