Auckland was founded by William Hobson in 1865. Maori already settled there around 1350 and sold a piece of land to the colonists. The colonists where able to buy the land, because they introduced fire arms. By doing so they disrupted the power balance between tribes. The Ngāti Whātua tribe needed protection in this time of war and asked the English to settle there. In the 19th century it boomed, because many English settled there to work in the port. In the area there are 50 known vulcanic sites. Luckily for the people, the area currently has no active vulcanos.
