Pennsylvania (/ˌpɛnsɪlˈveɪniə/ ^ⓘ, lit. 'Penn's forest country'), officially the Commonwealth of Pennsylvania (Pennsylvania Dutch: Pennsylvanie), is a landlocked state spanning the Mid-Atlantic, Northeastern, Appalachian, and Great Lakes regions of the United States. Pennsylvania borders Delaware to its southeast, Maryland to its south, West Virginia to its southwest, Ohio and the Ohio River to its west, Lake Erie and New York to its north, the Delaware River and New Jersey to its east, and the Canadian province of Ontario to its northwest.

Pennsylvania was founded in 1681 through a royal land grant to William Penn, the son of the state's namesake. Prior to that, between 1638 and 1655, a southeast portion of the state was part of New Sweden, a Swedish Empire colony. Established as a haven for religious and political tolerance, the colonial-era Province of Pennsylvania was known for its relatively peaceful relations with native tribes, innovative government system, and religious pluralism. Pennsylvania played a vital and historic role in the American Revolution and the ultimately successful quest for independence from the British Empire, hosting the First and Second Continental Congress, leading to the adoption of the Declaration of Independence and the formation of the Continental Army. On December 12, 1787, Pennsylvania became the second state to ratify the U.S. Constitution. The bloodiest battle of the American Civil War, at Gettysburg over three days in July 1863, proved the war's turning point, leading to the Union's preservation. Throughout the late 19th and 20th centuries, the state's manufacturing-based economy contributed to the development of much of the nation's early infrastructure, including key bridges, skyscrapers, and military hardware used in U.S.-led victories in World War I, World War II, and the Cold War.

Pennsylvania's geography is highly diverse. The Appalachian Mountains run through the center of the state; the Allegheny and Pocono mountains span much of Northeastern Pennsylvania; close to 60% of the state is forested. While it has no ocean shoreline, it has 140 miles (225 km) of waterfront along Lake Erie and the tidal Delaware River. (Full article...)
