Emma Kalanikaumakaʻamano Kaleleonālani Naʻea Rooke was queen of Hawaii as the wife of King Kamehameha IV from 1856 to his death in 1863. She was later a candidate for the throne but King Kalākaua was elected instead.

The Hawaiian Kingdom, also known as Kingdom of Hawaiʻi, was a sovereign state ruled by unelected dynastic families located in the Hawaiian Islands which existed from 1795 to 1893. It was established during the late 18th century when Hawaiian chief Kamehameha I, from the island of Hawaiʻi, conquered the islands of Oʻahu, Maui, Molokaʻi, and Lānaʻi, and unified them under one government. In 1810, the Hawaiian Islands were fully unified when the islands of Kauaʻi and Niʻihau voluntarily joined the Hawaiian Kingdom. Two major dynastic families ruled the kingdom, the House of Kamehameha and the House of Kalākaua.
