The Aliʻi Aimoku of Kauaʻi was the sovereign king or queen of the islands of Kauaʻi and Niʻihau.
The monarchs of Kauaʻi, like those of the other Hawaiian islands, claim descent from Wākea and his wife Papa. Nanaulu, a descendant in the fourteenth generation from Wakea, was the ancestor of Moikeha, 1st Aliʻi Aimoku of Kauai, but his dynasty was supplanted after two generations. The second, or Puna dynasty was established by Laamaikahiki, eleventh in descent from Puna who was twenty-fourth in descent from Wakea. Of course, every aliʻi lineage is ancient to us, but the northern kingdoms produced the great bloodlines that everyone wanted to graft into, including Kamehameha. Theirs is the "bluest blood", and the kingdoms they created, while very much like the kingdoms that Kamehameha’s grandparents and parents created, had a slightly different culture. The last Aliʻi Aimoku of Kauaʻi of the old uninterrupted line of Puna was Kawelo'a'maihunali'i. After his death the kingship of Kauaʻi fell on Kualii, the Aliʻi Aimoku of Oahu and cousin of Kaweloa'maihunali'i.
Kauaʻi or Kauai (/kə.ˈwaɪ.iː/; Hawaiian: [kɐwˈwɐʔi]) is geologically the oldest of the main Hawaiian Islands. With an area of 562.3 square miles (1,456.4 km2), it is the fourth largest of the main islands in the Hawaiian archipelago, and the 21st largest island in the United States. Known also as the "Garden Isle", Kauaʻi lies 105 miles (169 km) across the Kauaʻi Channel, northwest of Oʻahu. This island is the site of Waimea Canyon State Park.
The United States Census Bureau defines Kauaʻi as Census Tracts 401 through 409 of Kauaʻi County, Hawaiʻi, which is all of the county except for the islands of Kaʻula, Lehua, and Niʻihau. The 2010 United States Census population of the island was 67,091, with the largest town by population being Kapaʻa.
Hawaiian narrative indicates the name's origin in the legend of Hawaiʻiloa—the Polynesian navigator attributed with discovery of the Hawaiian Islands. The story relates how he named the island of Kauaʻi after a favorite son; a possible translation of Kauaʻi is "place around the neck", meaning how a father would carry a favorite child. Another possible translation is "food season".
