French explorer Marc-Joseph Marion du Fresne and 25 of his men are killed by Māori in New Zealand.

Marc-Joseph Marion du Fresne was a French privateer, East India captain, and explorer. The expedition he led to find the hypothetical Terra Australis in 1771 made important geographic discoveries in the south Indian Ocean and anthropological discoveries in Tasmania and New Zealand. In New Zealand, they spent longer living on shore than any previous European expedition. Half way through the expedition's stay, Marion was killed during a military assault by Ngare Raumati: one of the oldest Māori tribes from the Whangārei region.

Māori are the indigenous Polynesian people of mainland New Zealand. Māori originated with settlers from East Polynesia, who arrived in New Zealand in several waves of canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed a distinct culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some early Māori moved to the Chatham Islands, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori.

New Zealand is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island and the South Island —and over 600 smaller islands. It is the sixth-largest island country by area and lies east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland.
