The Iroquois (), also known as the Haudenosaunee or the "People of the Longhouse", are a group of tribes of indigenous people of North America. After the people who spoke Iroquoian came together as different tribes, which were mostly in what is now central and upstate New York, in the 16th century or earlier they came together in an group known today as the Iroquois League, or the "League of Peace and Power". The first Iroquois League was often known as the Five Nations, as it was made up of the Mohawk, Oneida, Onondaga, Cayuga and Seneca. After the Tuscarora nation joined the League in 1722, the Iroquois became known as the Six Nations. To this day, fifty "sachems" who represent different clans of the Iroquois meet at the Grand Council near Syracuse, New York.
