Kamehameha I, ca. 1758 – May 8, 1819), also known as Kamehameha the Great, conquered the Hawaiian Islands and formally established the Kingdom of Hawaiʻi in 1810. Born at Kapakai Kokoiki Heiau, Kohala, Hawaiʻi (Big) Island. Hawaiian legends claimed that a great king would one day unite the islands, and that the sign of his birth would be a comet. Halley's comet was visible from Hawaiʻi in 1758 and it is likely Kamehameha was born shortly after its appearance.
