The area comprising present-day Pennsylvania has been occupied by Native Americans since prehistoric times. When Europeans entered the area, it was occupied by tribes representing two linguistic groups, the Algonkian and the Iroquoian. Major Algonquian tribes included the Delaware, Conoy, Nanticoke and the Shawnee. Representatives of the Iroquois Confederacy in Pennsylvania were the Susquehannock and the Seneca.
