Iroquois Confederacy

The Iroquois Confederacy, also known as the Five Nations or the Haudenosaunee, was a powerful Native American confederation of tribes in what is now upstate New York. The five tribes that initially formed the confederation were the Mohawk, Oneida, Onondaga, Cayuga, and Seneca. Later, a sixth tribe, the Tuscarora, joined. The confederation was formed in the late 15th or early 16th century and was known for its political and military power. The Iroquois Confederacy had a sophisticated government and decision-making structure and played a significant role in the history of the northeastern United States.

Now, in times of upheaval and revolution, will you be able to prevent their extinction?
