Pennsylvania, US
Pennsylvania: State in the northeastern United States
About
Pennsylvania, officially the Commonwealth of Pennsylvania, is a U.S. state spanning the Mid-Atlantic, Northeastern, and Appalachian regions of the United States. The state is one of the original Thirteen Colonies that declared independence from Great Britain during the American Revolution, and it was the second to ratify the United States Constitution (the first being Delaware). As a result of this history, Pennsylvania has many sites associated with pre-Revolutionary War periods of America's early history.
Pennsylvania has been known as "the Keystone State" since 1937 because of its central location within the country's transportation system. It has played a critical role in American history by producing seven U.S. Presidents, being home to some of America's first industries and cities, and serving as a gateway to West Virginia and Ohio.
The state also contains a diverse set of natural habitats including mountains, forests, lakes and rivers; more than any other state except Alaska. Pennsylvania has a varied topography with a mix of urban areas and rural countryside. Commonly held beliefs include that Pennsylvania is a large agricultural state; that Philadelphia is "The City of Brotherly Love;" that Pittsburgh is "The Steel City;" and that all Pennsylvanians live in Amish country or in Philadelphia suburbs
