The Iroquois lived in what is now present-day New York State near the St. Lawerence River, and between the Adirondack Mountains and Niagara Falls. Between wars and conquest, they gained land in much of North Eastern North America, and Canada. During the Revolutionary War however, the Iroquois lost much land in New York. They were also called the "Five Nations". The Iroquois lived in two large, ranch houses that can hold up to 30 to 60 indians. These houses could be 150 feet long.
