The Aliʻi Aimoku was the sovereign king or queen of one of the four main Hawaiian Islands. The monarchs of island Oʻahu, like those of the other Hawaiian islands, claim descent from Wakea. Nanaulu, a fourteenth generation descendant of Wakea was the ancestor of Kumuhonua, 1st known King of Oahu, brother of Moiheka, 1st King of Kauai of the second dynasty. In 1783, Oahu was conquered by the King Kahekili II of Maui whose son Kalanikupule was, in turn, conquered by King Kamehameha I of Hawaii in 1795 at the Battle of Nuuanu. Many times the kings of Oahu had hegemony over the island of Molokai and used it as summer getaway. It was Oahu who brought forth the first Mo'iwahine or Queen regnant of any of the Hawaiian Islands.
