What were Iroquois tribes divided into?

Iroquois tribes were divided into three main groups known as the Haudenosaunee, or the Five Nations, which later became the Six Nations with the addition of the Tuscarora. These groups included the Mohawk, Oneida, Onondaga, Cayuga, Seneca, and later the Tuscarora. Each tribe had its own territory and governance but collaborated through a confederacy that emphasized unity and collective decision-making. The Iroquois League was a significant political and cultural alliance among these tribes.
