The coat of arms of Pennsylvania

Pennsylvania (/ˌpɛnsɪlˈvniə/ , 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...)

Aerial view of Presque Isle toward the east-northeast

Presque Isle State Park (/prɛsk/ PRESK) is a 3,112-acre (1,259 ha) Pennsylvania State Park on an arching, sandy peninsula jutting into Lake Erie, 4 miles (6 km) west of the city of Erie, in Millcreek Township, Erie County, Pennsylvania, in the United States. The peninsula sweeps northeastward, surrounding Presque Isle Bay along the park's southern coast. It has 13 miles (21 km) of roads, 21 miles (34 km) of recreational trails, 13 beaches for swimming, and a marina. Popular activities at the park include swimming, boating, hiking, biking, and birdwatching.

The recorded history of Presque Isle begins with the Erielhonan, a Native American tribe who gave their name to Lake Erie, and includes French, British, and American forts, as well as serving as a base for Commodore Oliver Hazard Perry's fleet in the War of 1812. With the growing importance of shipping on Lake Erie in the 19th century, Presque Isle became home to several lighthouses and what later became a United States Coast Guard station. In 1921, it became a state park, and as of 2007 it hosts over 4 million visitors per year, the most of any Pennsylvania state park. (Full article...)

Skyline of Center City

Philadelphia, commonly referred to as Philly, is the most populous city in the U.S. state of Pennsylvania and the sixth-most populous city in the nation, with a population of 1,603,797 in the 2020 census. The city is the urban core of the larger Delaware Valley, also known as the Philadelphia metropolitan area, the nation's seventh-largest and one of the world's largest metropolitan regions with 6.245 million residents in its metropolitan statistical area and 7.366 million residents in its combined statistical area.

Philadelphia is known for its extensive contributions to United States history. The city served as the nation's capital until 1800. It maintains contemporary influence in business and industry, culture, sports, and music. Philadelphia was founded in 1682 by William Penn, an English Quaker and advocate of religious freedom. The city served as the capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers. Philadelphia hosted the First Continental Congress in 1774, preserved the Liberty Bell, and hosted the Second Continental Congress during which the founders signed the Declaration of Independence. The U.S. Constitution was later ratified in Philadelphia at the Philadelphia Convention of 1787. Philadelphia remained the nation's largest city until 1790, served as the nation's first capital from May 10, 1775, until December 12, 1776, and on four subsequent occasions during and following the American Revolution, including from 1790 to 1800 during the construction of the new national capital of Washington, D.C.

A 1752 map of Philadelphia

The city of Philadelphia was founded in 1682 by William Penn in the English Crown Province of Pennsylvania between the Delaware and Schuylkill rivers. Before then, the area was inhabited by the Lenape people. Philadelphia quickly grew into an important colonial city and during the American Revolution was the site of the First and Second Continental Congresses. After the Revolution the city was chosen to be the temporary capital of the United States. At the beginning of the 19th century, the federal and state governments left Philadelphia, but the city remained the cultural and financial center of the country. Philadelphia became one of the first U.S. industrial centers and the city contained a variety of industries, the largest being textiles.

After the American Civil War Philadelphia's government was controlled by a Republican political machine and by the beginning of the 20th century Philadelphia was described as "corrupt and contented." Various reform efforts slowly changed city government with the most significant in 1950 where a new city charter strengthened the position of mayor and weakened the Philadelphia City Council. At the same time Philadelphia moved its supports from the Republican Party to the Democratic Party, which has since created a strong Democratic organization. (Full article...)

During the American Civil War, the Commonwealth of Pennsylvania played a critical role in the Union, providing a substantial supply of military personnel, equipment, and leadership to the Federal government. The state raised over 360,000 soldiers for the Federal armies. It served as a significant source of artillery guns, small arms, ammunition, armor for the new revolutionary style of ironclad types of gunboats for the rapidly expanding United States Navy, and food supplies. The Phoenixville Iron Company by itself produced well over 1,000 cannons, and the Frankford Arsenal was a major supply depot.

Pennsylvania was the site of the bloodiest battle of the war, the Battle of Gettysburg, which became widely known as one of the turning points of the Civil War. Numerous more minor engagements and skirmishes were also fought in Pennsylvania during the 1863 Gettysburg Campaign, as well as the following year during a Confederate cavalry raid that culminated in the burning of much of Chambersburg, Pennsylvania.
