The Kanien'kehá:ka are in the easternmost section of the Haudenosaunee, or Iroquois Confederacy. They are an Iroquoian-speaking Indigenous people of North America, with communities in southeastern Canada and northern New York State, primarily around Lake Ontario and the St. Lawrence River. As one of the five original members of the Iroquois League, the Mohawk are known as the Keepers of the Eastern Door – the traditional guardians of the Iroquois Confederation against invasions from the east.

The Iroquois, also known as the Five Nations, and later as the Six Nations from 1722 onwards; alternatively referred to by the endonym Haudenosaunee are an Iroquoian-speaking confederacy of Native Americans and First Nations peoples in northeast North America. They were known by the French during the colonial years as the Iroquois League, and later as the Iroquois Confederacy, while the English simply called them the "Five Nations". The peoples of the Iroquois included the Mohawk, Oneida, Onondaga, Cayuga, and Seneca. After 1722, the Iroquoian-speaking Tuscarora people from the southeast were accepted into the confederacy, from which point it was known as the "Six Nations".
