Pennsylvania, officially the Commonwealth of Pennsylvania, is a state in the Mid-Atlantic, Northeastern, and Appalachian regions of the United States. The Commonwealth is bordered by Delaware to the southeast, Maryland to the south, West Virginia to the southwest, Ohio to the west, Lake Erie, and the Canadian province of Ontario to the northwest, New York to the north, and New Jersey to the east, while the Appalachian Mountains run through its middle.

The state is one of the Thirteen original founding states of the United States; it came into being in 1681 because of a royal land grant to William Penn, the son of the state’s namesake.  It was the second state to ratify the United States Constitution, on December 12, 1787. Independence Hall, where the United States Declaration of Independence and United States Constitution were drafted, is in Philadelphia, the state’s largest city.

Historically, as of 1600, the tribes living in Pennsylvania were the Algonquian Lenape (also Delaware), the Iroquoian Susquehannock, and Petun (also Tionontati, Kentatentonga, Tobacco, Wenro) and the presumably Siouan Monongahela Culture, who may have been the same as a little-known tribe called the Calicua, or Cali. Other tribes who entered the region during the colonial era were the Trockwae, Tutelo, Saponi, Shawnee, Nanticoke, Conoy Piscataway, Iroquois Confederacy—likely among others. Other tribes, like the Erie, may have once held land in Pennsylvania, but no longer did so by the year 1600.
