ʻUmi-a-Līloa (fifteenth century) was a ruling ali'i-ai-moku (district high chief of Hawai'i) who inherited religious authority of Hawai'i from his father, High Chief Liloa, whose line is traced, unbroken to Hawaiian "creation". His mother was Akahi. She was of a lesser line of chiefs who Liloa had fallen in love with when he discovered her bathing in a river. He became Chief after the death of his half-brother , who inherited the lands of his father to rule. Umi-a-Liloa was considered a just ruler, religious and the first to unite almost all of [Hawaii (island]. The legend of Umi is one of the most popular hero sagas in Hawaiian history. While there is probably embellishment to the story, as many sagas do, a portion of historical accuracy remains.
