The Real Mystery Behind Moana: After 1,700 Years, Why Did Polynesians Suddenly Sail East?

The story behind Moana draws on one of the great mysteries of Pacific history: why Polynesian voyagers resumed long-distance eastward settlement after roughly 1,700 years of relative stability in Samoa and Tonga. New climate evidence may help explain the shift. Between AD 900 and 1100, ancestral Polynesians embarked on a remarkable era of navigation in double-hulled canoes, reaching Hawai'i, Aotearoa and Rapa Nui within the following century. The spread of sweet potatoes across Pacific islands also suggests contact with the Americas. The research connects changing environmental conditions with the seafaring knowledge and cultural heritage that made this extraordinary expansion possible.
