The coat of arms of Pennsylvania
Pennsylvania ( PEN -sil-VAY -nee-ə , lit. ' Penn's forest country ' ), officially the Commonwealth of Pennsylvania (Pennsylvania Dutch : Pennsylvanie ), is a US state spanning the Mid-Atlantic , Northeastern , Appalachian , and Great Lakes regions of the United States . It 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 via Lake Erie .
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... )

Priestley Avenue side of the Joseph Priestley House in 2007
The Joseph Priestley House was the American home of eighteenth-century British theologian , Dissenting clergyman , natural philosopher (and co-discoverer of oxygen), educator, and political theorist Joseph Priestley (1733–1804) from 1798 until his death. Located in Northumberland, Pennsylvania , the house, which was designed by Priestley's wife Mary, is Georgian with Federalist accents. The Pennsylvania Historical and Museum Commission (PHMC) operated it as a museum dedicated to Joseph Priestley from 1970 to August 2009, when it closed due to low visitation and budget cuts. The house reopened in October 2009, still owned by the PHMC but operated by the Friends of Joseph Priestley House (FJPH).
Fleeing religious persecution and political turmoil in Britain, the Priestleys emigrated to the United States in 1794 seeking a peaceful life. Hoping to avoid the political troubles that had plagued them in Britain and the problems of urban life they saw in the United States, the Priestleys built a house in rural Pennsylvania. Nevertheless, political disputes and family troubles dogged Priestley during the last ten years of his life. (

Penn depicted in an 18th century illustration
William Penn (24 October [O.S. 14 October] 1644 – 10 August [O.S. 30 July] 1718) was an English writer, religious thinker, and influential Quaker who founded the Province of Pennsylvania during the British colonial era . Penn, an advocate of democracy and religious freedom , was known for his amicable relations and successful treaties with the Lenape Native Americans who had resided in present-day Pennsylvania prior to European settlements in the state.
In 1681,
King Charles II granted a large piece of his
North American land holdings along the
North Atlantic Ocean coast to Penn to offset debts he owed Penn's father, the admiral and politician
Sir William Penn . The land included the present-day states of Pennsylvania and
Delaware . The following year, in 1682, Penn left
England for what was then
British America , sailing up
Delaware Bay and the
Delaware River past earlier
Swedish and
Dutch riverfront colonies in what is present-day
New Castle, Delaware . On this occasion, the colonists pledged allegiance to Penn as their new
proprietor , and the first
Pennsylvania General Assembly was held. (
