Te Rauparaha was a Māori rangatira, warlord, and chief of the Ngāti Toa iwi. One of the most powerful military leaders of the Musket Wars, Te Rauparaha fought a war of conquest that greatly expanded Ngāti Toa southwards, receiving the epithet "the Napoleon of the South". He remains one of the most prominent and celebrated New Zealand historical figures.

Ngāti Toa, Ngāti Toarangatira or Ngāti Toa Rangatira, is a Māori iwi (tribe) based in the southern North Island and in the northern South Island of New Zealand. Its rohe extends from Whanganui in the north, Palmerston North in the east, and Kaikōura and Hokitika in the south. Ngāti Toa remains a small iwi with a population of only about 9000. The iwi is centred around Porirua, Plimmerton, Kāpiti, Blenheim and Arapaoa Island. It has four marae: Takapūwāhia and Hongoeka in Porirua City, and Whakatū and Wairau in the north of the South Island. Ngāti Toa's governing body has the name Te Rūnanga o Toa Rangatira.
