Māori culture has predominated for most of New Zealand's history of human habitation. Polynesians reached the islands of New Zealand about 1280. Over the ensuing centuries of Polynesian expansion and settlement, Māori culture developed from its Polynesian roots. Māori established separate tribes, built fortified villages (Pā), hunted and fished, traded commodities, developed agriculture, arts and weaponry, and kept a detailed oral history. Regular European contact began from 1800, and British immigration proceeded rapidly, especially from 1855.
