Hongi Hika was a New Zealand Māori rangatira (chief) and war leader of the iwi of Ngāpuhi. He was a pivotal figure in the early years of regular European contact and settlement in New Zealand. As one of the first Māori leaders to understand the advantages of European muskets in warfare, he used European weapons to overrun much of northern New Zealand in the early nineteenth century Musket Wars. He was however not only known for his military prowess; Hongi Hika encouraged Pākehā (European) settlement, built mutually beneficial relationships with New Zealand's first missionaries, introduced Māori to Western agriculture and helped put the Māori language into writing. He travelled to England and met King George IV. His military campaigns, along with the other Musket Wars, were one of the most important motivators for the British annexation of New Zealand and subsequent Treaty of Waitangi with Ngāpuhi and many other iwi.

The Musket Wars were a series of as many as 3,000 battles and raids fought throughout New Zealand among Māori between 1806 and 1845, after Māori first obtained muskets and then engaged in an intertribal arms race in order to gain territory or seek revenge for past defeats. The battles resulted in the deaths of between 20,000 and 40,000 people and the enslavement of tens of thousands of Māori and significantly altered the rohe, or tribal territorial boundaries, before the signing of the Treaty of Waitangi in 1840. The Musket Wars reached their peak in the 1830s, with smaller conflicts between iwi continuing until the mid 1840s; some historians argue the New Zealand Wars were a continuation of the Musket Wars. The increased use of muskets in intertribal warfare led to changes in the design of pā fortifications, which later benefited Māori when engaged in battles with colonial forces during the New Zealand Wars.
