Read the passage about the iroquois.

around 1570, the iroquois made an oral contract—an agreement made through spoken words. originally, it was memorized and represented in beaded wampum belts. later, it was written down. we now call this agreement the iroquois constitution. this document provides an example of an early american political document and describes iroquois values. the iroquois constitution declared that the five nations would join into one peaceful iroquois confederacy. it also created rules for a common council to unite the nations. the confederacy lasted for 200 years, until the american revolution. during the time it existed, it provided the iroquois with a united front for dealing with european colonists in the 17th and 18th centuries. historians debate the impact of the iroquois constitution on the us constitution. however, they agree that the iroquois constitution was the first to lay out division of power within a government.
