Kaumualiʻi (c. 1778–May 26, 1824) was the last independent aliʻi nui (supreme ruler of the island) of Kauaʻi and Niʻihau before becoming a vassal of Kamehameha I within the unified Kingdom of Hawaiʻi in 1810. He was the 23rd high chief of Kauaʻi and reigned during 1794–1810. Although he was sometimes known as George Kaumualiʻi, he should not be confused with his son, who is more commonly known by that name. In Hanama'ulu, the King Kaumuali'i Elementary School is named after Kauai's last reigning chief. Kaumualiʻi was the only son of Queen Kamakahelei, aliʻi nui of Kauaʻi and Niʻihau, and her husband, Aliʻi Kāʻeokūlani (c. 1754–1794), regent of Maui and Molokaʻi. Kāʻeokūlani was the younger son of Kekaulike, the 23rd Aliʻi Aimoku and Moʻi of Maui. He became the co-king and effectively ruler of Kauaʻi by his marriage. When Kamakahelei died in 1794, she passed their titles and positions to the 16-year-old Kaumualiʻi, who reigned under the regency of Chief Inamoʻo until he came of age. His first wife and queen was his half-sister Kawalu of O'ahu. His second wife was his half-sister, Kaʻapuwai Kapuaʻamohu of Kōloa; his third and final wife was the queen regent Kaʻahumanu (1768–1832), Kamehameha's widow. Kauaʻi and Niʻihau had eluded Kamehameha's control since he first tried to add them to his kingdom in 1796, a year after Kaumualiʻi became king. At that time, the governor of the Island of Hawai'i led a rebellion against Kamehameha forcing him to return home. Kamehameha tried again in 1803, but disease ravaged his armies, and he called a retreat to heal his men and work on his strategy. Over the next years, Kamehameha amassed the largest armada Hawaiʻi had ever seen: foreign-built schooners and massive war canoes armed with cannons to carry his vast army. Kaumualiʻi decided to negotiate a peaceful resolution rather than resort to bloodshed. The move was supported by Kamehameha as well as the people of Kauaʻi and the foreign sandalwood merchants on the island, whose trade was hurt by the constant feuding.
