–Making of a Country–

The arrival of Europeans transformed North America’s forests, including those in the Pennsylvania Colony.

Expanding territory

Westward Expansion in the 18th century encroached on Algonquian‐speaking tribes in the area, such as the Delaware, Seneca and the Shawnee. The French and Indian War and the American Revolution brought Native Americans into direct conflict with the English colonists / U. S. government in central and western Pennsylvania. Significant treaties with the Seneca and Shawnee opened up lands in western Pennsylvania to American settlement in the 1780s and 90s.
