The
Iphigenia arrived in Maui on December 6 or 7, 1788, where was greeted by his brother-in-law "Harwallenee" [sic]. The ship departed for Hawaiʻi, stopping at Kawaihae, Kailua and finally docking at
Kealakekua Bay where they were greeted by
Kamehameha I. According to historian
Samuel Kamakau, Kamehameha I persuaded Kaʻiana to stay in Hawaiʻi, saying, "Here is land, here are chiefs, here are commoners. Let us live on Hawaii. Do not return to Kauai and Oahu." The
Iphigenia would later sail to Kauai to bring Kaʻiana's relatives, including his wife and son, and his brothers and their relatives to Hawaiʻi. Kaʻiana and his brothers would settle on Hawaiʻi and help Kamehameha I secure a larger arsenal of Western firearms and ammunition from visiting foreign ships to use in his conquest of the Hawaiian Islands. At this time, the island of Hawaiʻi was divided between the Kamehameha I and his cousin
Keōua Kūʻahuʻula, whom the brothers would help Kamehameha defeat and kill in 1791. Kaʻiana was installed as district chief of
Puna by Kamehameha I. In January 1793, British explorer
George Vancouver visited Hawaiʻi and described how the two brothers were of a "turbulent, treacherous, and ungrateful dispositions." The British explorer wrote, "Nomatahah (Nāmākēhā) and Tamaahmootoo (
Kameʻeiamoku) are artful, designing, and restless characters, and have dispositions to act on all occasions of hazard, or unlawful attempt, in conjunction with Tianna (Kaʻiana)." Vancouver also alluded that the two brothers were involved in the capture of the American ship
Fair American. In 1795, Kaʻiana and his brother were ordered by Kamehameha I to join him on his campaign against
Kalanikūpule, the
aliʻi nui of Maui and Oʻahu and the son and successor of Kahekili II. Kaʻiana and Nāhiʻōleʻa would answer the call, but Nāmākēhā ignored the summons. On Oʻahu, Kaʻiana and Nāhiʻōleʻa, dissatisfied with being excluded from Kamehameha's war council, defected to Kalanikūpule. Kaʻiana‘s wife Kekupuohi refused to defect against Kamehameha. Kaʻiana and Nāhiʻōleʻa were both killed at the
Battle of Nuʻuanu in 1795. ==In popular culture==
