Te Rauparaha (1760s – 27 November 1849) was a Māori rangatira (chief) and war leader of the Ngāti Toa tribe who took a leading part in the Musket Wars. He was influential in the original sale of land to the New Zealand Company and was a participant in the Wairau Incident in Marlborough.
From 1807, muskets became the weapon of choice and partly changed the character of tribal warfare. In 1819 Te Rauparaha joined with a large war party of Ngāpuhi led by Tāmati Wāka Nene; they probably reached Cook Strait before turning back.
Over the next few years the intertribal fighting intensified, and by 1822 Ngāti Toa and related tribes were being forced out of their land around Kāwhia after years of fighting with various Waikato tribes often led by Te Wherowhero. Led by Te Rauparaha they began a fighting retreat or migration southwards (this migration was called Te-Heke-Tahu-Tahu-ahi), conquering hapu and iwi as they went south. This campaign ended with Ngāti Toa controlling the southern part of the North Island and particularly the strategically placed Kapiti Island, which became the tribal stronghold for a period.
