Elizabeth Kekaʻaniau La‘anui Pratt (1834-1928) was a Hawaiian high chiefess and historian. Born in Waialua, she was named after Queen Ka‘ahumanu, her grandmother by adoption, whose baptized name was Elizabeth. Raised in the inner circle of Kamehameha I, Elizabeth was educated at the Chiefs’ Children’s School, where five of her sixteen classmates would go on to serve as monarchs of the Kingdom of Hawaii. A close friend of Emma, queen consort of Kamehameha IV, she eventually served as her lady in waiting and was active in the royal court. In 1864, she married Franklin Seaver Pratt, an American businessman and naturalized citizen of the kingdom. A lifelong ally of Queen Emma, Elizabeth supported her failed candidacy for the royal election of 1874, which led to rioting after popular support for the Queen was ignored by the assembly gathered at Honolulu Courthouse. During the period of political unrest preceding the overthrow of the Kingdom of Hawaii, the Pratts moved briefly to San Francisco, where Franklin acted as Hawaiian Consul General in the Pacific states. Toward the end of her life, she participated in numerous ceremonies to honor the history of the Hawaiian Kingdom, and in 1920 wrote her History of Keoua Kalanikupuapa-i-kalani-nui, Father of Hawaiian Kings, a genealogical study of the House of Keōua Nui.
