Answer: By forming the The Iroquois Confederacy
Step-by-step explanation:
In the 16th century, five Iroquois nations being the Onondaga, the Mohawk, the Oneida, the Seneca, and the Cayuga came together under the direction of the leaders Deganawida and Hiawatha.
These two leaders had seen that fighting would be the end of the Iroquois and so resolved to do something about it. They came up with the Great Laws which were both rules and guidelines for peaceful coexistence and founded a Grand Council with representatives from the five tribes.
This brought peace through compromise and communication and helped the Iroquois form a stronger nation that could protect their land and people.
