The Iroquois, before being the Iroquois were called the Haudenosaunee. The Iroquois often fought the Algonkins, a neighboring tribe, over land. The Iroquois lived in longhouses, a long house with no windows, only a door on each end and small holes in the roof to let air in. Fighting among the tribes led the Iroquois to make a confederation and they called it the Iroquois league.
