Mitiaro: History
According to oral tradition, Mitiaro was settled from Atiu, and was historically dominated by that island. It was first discovered by Europeans when John Williams of the London Missionary Society arrived in 1823. He left behind a Polynesian teacher, Taua, who began converting the islanders to Christianity. The estimated population at that time was less than 100 inhabitants. During the 1840s the island was attacked again by Atiuans.
In 1888 Mitiaro became a British protectorate as part of the Cook Islands Federation. In 1901 it was annexed by New Zealand.
