Kaihikapu-a-Kakuhihewa was a Hawaiian chief of the island of Oahu. He ruled portions of Waikiki and Ewa and served as a district chief of those districts. He like his father was known for his merry way simialar to that of the last king of Hawaii, Kalakaua.
He was the second son of Kakuhihewa, the 15th Alii Aimoku of Oahu, and of his wife Kaea-a-Kalona or Kahaiaonuiakauailana, the daughter of Napulanahumahiki. When Kakuhihewa died, the office and dignity of Moi of Oahu descended to Kanekapu, Kaihikapu's eldest brother. In other respects the island of Oahu appears to have been divided between the three oldest brothers, Kanekapu, Kaihikapu-a-Kakuhihewa, and Kauakahinui-a-Kakuhihewa. This situation is similar to the Carolingian Empire after the Treaty of Verdun with Louis the German and Charles the Bald both respecting their brother Lothair I, the rightful heir of the imperial titles. Kaihikapu-a-Kakuhihewa, though acknowledging his brother Kanekapu-a-Kakuhihewa as the Moi of Oahu, kept his glorious and brilliant court sometimes at Ewa, sometimes at Waikiki. His other siblings were a brother, Kalehunapaikua, and a sister Makakaialiilani.
We know but little of the history of his life. The Meles and legends merely allude to certain events known to have transpired during his time as if they were too well known in the community at the time those accounts in verse or prose were composed to require farther details. Thus there can be no doubt that it was during his time that Kauhi-a-Kama, the Moi of Maui, started an armed expedition to Oahu, landed at Waikiki, and met a violent death there at the hands of the Oahu chiefs; but we know not the cause of the quarrel or the invasion, nor if Kaihikapu-a-Kakuhihewa was personally present at Waikiki and shared in the battle and took part in the outrage committed on Kauhi-a-Kama's body at the Heiau of Apuakehau.
It is known that the great civil war between Kawelo-a-Maihunalii and his cousin or near relative, Kawelo-Aikanaka, on Kauai, occurred during this period. Kawelo-a-Maihunali's wife belonged to the Kalona family of Oahu, and he had obtained lands in Ewa on the slope ascending to the Kolekole pass of the Waianae mountains. Kaihikapu-a-Kakuhihewa, seeing that he was a near relative, assisted him with men, arms, and canoes during the war; but we learn nothing from those legends that throws any light on the contentions which distracted the island of Kauai between the time of Kaweloaikanaka and that of Kaweloamaihunalii.
Kaihikapu-a-Kakuhihewa's wife was the High Chiefess Ipuwai-a-Hoalani, a daughter of Hoalani and Kaua Kamakaohua; the former a brother to Kakuhihewa's wife, Kaakaualani, the latter a daughter of Kamakaohua, a chief in Kohala, Hawaii, to whom belonged the Heiau of Muleiula, on the land of Kahei. With this wife Kaihikapu-a-Kakuhihewa had a daughter named Kauakahikuaanaauakane, who married Iwikauikaua, and thus became the grandmother of the famous Kalanikauleleiaiwi, the wife of Keaweikekahialiiokamoku, king of Hawaii.
