Ancient Hawaiʻi is the period of Hawaiian human history preceding the unification in 1810 of the Kingdom of Hawaiʻi by Kamehameha the Great. Researchers had based their estimates of first settlement by Polynesian long-distance navigators sometime between 300 and 800. In 2010, a study was published based on radiocarbon dating of more reliable samples and it suggests that the islands were settled much later, within a short timeframe, in c. 1219–1266.
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.
The rich natural resources supported a relatively dense population, organized by a ruling class and social system with religious leaders. Captain James Cook made the first known European contact with ancient Hawaiians in 1778. He was followed by many other Europeans and Americans.
There have been changing views about initial Polynesian discovery and settlement of Hawai'i.Radiocarbon dating in Hawai'i initially indicated a possible settlement as early as 124.Patrick Vinton Kirch's books on Hawaiian archeology, standard textbooks, date the first Polynesian settlements to about 300 with more recent suggestions by Kirch as late as 600. Other theories suggest dating as late as 700 to 800.
In 2010 researchers announced new findings using revised, high-precision radiocarbon dating based on more reliable samples than were previously used in many dating studies. This new data indicates that the period of eastern and northern Polynesian colonization took place much later, in a shorter time frame of two waves: the "earliest in the Society Islands A.D. ∼1025–1120, four centuries later than previously assumed; then after 70–265 y, dispersal continued in one major pulse to all remaining islands A.D. ∼1190–1290." According to this research, settlement of the Hawaiian Islands took place circa 1219–1266 CE. This rapid colonization is believed to account for the "remarkable uniformity of East Polynesia culture, biology and language."
