Final answer:
A feature of the League of the Iroquois resembling the U.S. Congress is the council of representatives from member tribes, paralleling Congress's representation from various states. Their governance system influenced the adoption of democratic principles within the U.S. Constitution.
Step-by-step explanation:
One feature of the League of the Iroquois that resembles the design and process found in the U.S. Congress is the concept of a governing council made up of representatives. The Iroquois Confederacy, comprising several Native American tribes including the Mohawk, Oneida, Onondaga, Cayuga, Seneca, and later the Tuscarora, was governed by a council of fifty sachems. These sachems were essentially leaders from each of the member tribes, a structure that bears similarity to the U.S. Congress where representatives from different states come together to legislate and govern.
Furthermore, the principles of checks and balances and the separation of powers were evident within the Iroquois system. This framework influenced American founding figures, such as Benjamin Franklin and George Washington, who admired the Iroquois Confederacy's political organization. Consequently, many of these democratic principles were incorporated into the United States Constitution.
