Kalaninuiamamao (sometimes called Ka-I-i-Mamao or Kaeamamao) was a prince of the Big Island of Hawaiʻi, or 1st Aliʻi Nui of Kaʻū, an ancestor of the Queen Liliuokalani.
During his father's lifetime, he had established Kaiʻiʻmamao as Aliʻi Aimoku, principal chief of the District of Kaʻū.
After the death of their father, the Big Island was divided with the brothers controlling only the Northern portions of the Big Island since Mokulani, who ruled over Hilo, Hāmākua, and part of Puna, declared himself independent of the two brothers, who apparently were unable to enforce their claims to the throne.
[2] Kalaninuiamamao visited Kauai as well as Oahu, where he fell in love with the Chiefess Kamakaimoku, and engaged her to come to Hawaii as his bride.
Their union was not of long duration, for within a year or two she left him and became the wife of his brother Keeaumoku Nui, and to him she bore another son, Keōua.
