When Europeans arrived in the Americas during the 16th and 17th centuries, they found that some Native American tribes had created alliances, or confederacies. These agreements allowed the member tribes of the confederacy to control trade and keep the peace in their region. This book explains how these Native American confederacies were formed, discusses some famous examples like the Iroquois Confederacy, and explains how Native American groups continue to work together for the good of all tribes in the present day.
