Tahiti of ocean, was made possible by using outrigger canoes that were up to twenty or thirty meters long and could transport families as well as domestic animals. In 1769, for instance, James Cook mentions a great traditional ship ("va'a") in Tahiti that was long, and could be propelled by sail or paddles. In 2010, an expedition on a simple outrigger canoe with a sail retraced the route back from Tahiti to Asia. Before the arrival of the Europeans the island was divided into different chiefdoms, very precise territories dominated by a single clan. These chiefdoms were linked to each other
Kingdom of Tahiti to stop the warring. As king, Pōmare I succeeded in uniting the different chiefdoms of Tahiti into a single kingdom, composed of the islands of Tahiti itself, Moʻorea, Mehetiʻa, and the Tetiʻaroa group. His service as the first king of unified Tahiti ended when he abdicated in 1791, but he remained the regent of Tahiti from 1791 until 1803. He married four times and had two sons and three daughters. By now, islanders were passing to each other diseases that had arrived with the Europeans: diseases for which they had undeveloped immunities. Many islanders were dying. In 1803, Pomare died.
