Of course, every aliʻi lineage is ancient, but the northern kingdoms produced the great bloodlines that everyone wanted to graft into, including Kamehameha.
After his overthrow by Kaweloamaihunalii and that monarch's eventual death, the kingdom of Kauaʻi fell to Kualii of Oahu.
In 1810, Kaumualiʻi, negotiated a peaceful end to his power with King Kamehameha I of Hawaii, in an effort to avoid bloodshed.
The agreement allowed Kaumualiʻi to remain aliʻi nui until his death, when all lands would revert to Kamehameha's heir.
After his death in 1824, his son George Kaumualiʻi took back his birth name Humehume and attempted to re-establish an independent on Kauaʻi, but was also eventually captured and taken to Honolulu.
