Ancient Hawaii is the period of Hawaiian history preceding the establishment in 1795 of the Kingdom of Hawaiʻi by Kamehameha the Great. Traditionally, researchers estimated the first settlement of the Hawaiian islands as having occurred sporadically between 400 and 1100 CE by Polynesian long-distance navigators from the Samoan, Marquesas, and Tahiti islands within what is now French Polynesia. In 2010, a study was published based on radiocarbon dating of more reliable samples which suggests that the islands were settled much later, within a short timeframe, in about 1219 to 1266.
The islands in Eastern Polynesia have been characterized by the continuities among their cultures, and the short migration period would be an explanation of this result. Diversified agroforestry and aquaculture provided sustenance for Native Hawaiian cuisine. Tropical materials were adopted for housing. Elaborate temples (called heiau) were constructed from the lava rocks available.
