The last part of the Pacific Ocean to be settled was the huge expanse of the central Pacific itself with its thousands of tiny islands and atolls. We explore the people who left Asia to become the Polynesians, their navigation and extraordinary sailing skills. We see the sorts of societies they made in Hawaii, in Easter Island, Tahiti and New Zealand. We think about what happened when European sails appeared on their horizon to end the isolation of more than half the worlds people.
