What ideas in the constitution did the framers adopt from the league of the Iroquois?

The framers of the U.S. Constitution were influenced by the democratic principles and confederate structure of the Iroquois Confederacy, particularly in their emphasis on unity among diverse groups and collective decision-making. The Iroquois system highlighted the importance of consensus and representation, which inspired the framers to incorporate checks and balances and a federal structure that allowed for cooperation among states. Additionally, the Iroquois' model of a council governing the various tribes informed the creation of a bicameral legislature in the Constitution. These elements reflected a desire for a balanced government that respected both individual states and the need for a unified nation.
