The flag of the Iroquois represents the Hiawatha wampum belt. The belt is comprised of thirty eight rows, having a heart as a great tree in the center, on either side there are two squares, all are connected with the heart by white rows of wampum. The belt is the emblem of unity among the Five Nations.
The first square on the left represents the Mohawk Nation, Keeper of the Eastern Door. The inner square on the left, nearest the heart represents the Oneida Nation. The white tree in the middle represents the Onondaga Nation. This tree also means that the heart of the Five Nations is single in loyalty to the Great Law of Peace. The Great Peace is lodged in the heart, meaning that the Haudenosaunee council fire is to burn at Onondaga, serving as the capitol of the Haudenosaunee. It also means that the authority is given to advance the cause of peace. The inner square to the right of the heart represents the Cayuga Nation. The last square, the one furthest to the right represents the Seneca Nation, known as Keeper of the Western Door.
The two lines extending from each side of the squares of the belt, from the Mohawk and Seneca Nations represents a path of peace that other Nations are welcome to travel, to take shelter beneath the Great Tree of Peace, and join the Iroquois Confederacy.
