The accidental shooting of a Māori by an English sailor results in the opening of the Wanganui Campaign of the New Zealand land wars.
The Whanganui campaign was a brief round of hostilities in the North Island of New Zealand as indigenous Mori fought British settlers and military forces in 1847. The campaign, which included a siege of the fledgling Whanganui settlement (then named "Petre"), was among the earliest of the 19th century New Zealand Wars that were fought over issues of land and sovereignty.
The Māori (, Māori: [ˈmaːɔɾi] (listen)) are the indigenous Polynesian people of mainland New Zealand (Aotearoa). 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 their own distinctive 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.Initial contact between Māori and Europeans, starting in the 18th century, ranged from beneficial trade to lethal violence; Māori actively adopted many technologies from the newcomers. With the signing of the Treaty of Waitangi in 1840, the two cultures coexisted for a generation. Rising tensions over disputed land sales led to conflict in the 1860s, and massive land confiscations, to which Māori responded with fierce resistance. After the Treaty was declared a legal nullity in 1877, Māori were forced to assimilate into many aspects of Western culture. Social upheaval and epidemics of introduced disease took a devastating toll on the Māori population, which fell dramatically. By the start of the 20th century, the Māori population had begun to recover, and efforts have been made, centring on the Treaty of Waitangi, to increase their standing in wider New Zealand society and achieve social justice.
Traditional Māori culture has thereby enjoyed a significant revival, which was further bolstered by a Māori protest movement that emerged in the 1960s. However, disproportionate numbers of Māori face significant economic and social obstacles, and generally have lower life expectancies and incomes compared with other New Zealand ethnic groups. They suffer higher levels of crime, health problems, and educational under-achievement. A number of socio-economic initiatives have been instigated with the aim of "closing the gaps" between Māori and other New Zealanders. Political and economic redress for historical grievances is also ongoing (see Treaty of Waitangi claims and settlements).
In the 2018 census, there were 775,836 people in New Zealand identifying as Māori, making up 16.5 percent of the national population. They are the second-largest ethnic group in New Zealand, after European New Zealanders ("Pākehā"). In addition, more than 140,000 Māori live in Australia. The Māori language is spoken to some extent by about a fifth of all Māori, representing three percent of the total population. Māori are active in all spheres of New Zealand culture and society, with independent representation in areas such as media, politics, and sport.
