Moriori genocide

The Moriori genocide was the mass murder, enslavement, and cannibalisation of the Moriori people, the indigenous ethnic group of the Chatham Islands, by members of Ngāti Mutunga and Ngāti Tama, two Māoriiwi from mainland New Zealand, from 1835 to 1863. The invaders murdered around 300 Moriori and enslaved the remaining population. This, together with diseases brought by Europeans, caused the population to drop from 1,700 in 1835 to 100 in 1870. The last individual of sole-Moriori ancestry, Tommy Solomon, died in 1933.
