British conquer the Maori
Well, no: Treaty of Waitangi.
As some words in the English treaty did not translate directly into the written Māori language of the time, the Māori text is not an exact translation of the English text, particularly in relation to the meaning of having and ceding sovereignty.[11][12] These differences created disagreements in the decades following the signing, eventually contributing to the New Zealand Wars of 1845 to 1872 and continuing through to the Treaty of Waitangi settlements starting in the early 1990s.
During the second half of the 19th century Māori generally lost control of much of the land they had owned, sometimes through legitimate sale, but often by way of unfair deals, settlers occupying land that had not been sold, or through outright confiscations in the aftermath of the New Zealand Wars. In the period following the New Zealand Wars, the New Zealand government mostly ignored the treaty, and a court judgement in 1877 declared it to be “a simple nullity”.
The result is the same, but it was a battle of politicians and shady lawyers rather than force of arms. I’m not saying it’s better to lose your rights and property that way than on a battlefield, but calling it a conquest makes it seem like some kind of achievement.
