The coat of arms of Pennsylvania

Pennsylvania, officially the Commonwealth of Pennsylvania, is a 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's most populous city is Philadelphia.

Pennsylvania was founded in 1681 through a royal land grant to William Penn, the son of the state's namesake. Before that, between 1638 and 1655, a southeast portion of the state was part of New Sweden, a Swedish 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 later 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 in Philadelphia, which formed the Continental Army and elected George Washington as its commander in 1775 during the American Revolutionary War, and unanimously adopted the Declaration of Independence the following year. In 1787, following the establishment of the nation's independence, the Constitution of the United States, now the world's oldest and longest-standing written and codified national constitution, was written at the Constitutional Convention in Philadelphia, and was ratified in Philadelphia the following year. On December 12, 1787, Pennsylvania was the second state to ratify the U.S. Constitution. (Full article...)

Portrait of Priestley, 1801

Joseph Priestley FRS (/ˈprstli/; 24 March 1733 – 6 February 1804) was an English chemist, Unitarian, natural philosopher, separatist theologian, grammarian, multi-subject educator and classical liberal political theorist. He published over 150 works, and conducted experiments in several areas of science.

Priestley is credited with his independent discovery of oxygen by the thermal decomposition of mercuric oxide, having isolated it in 1774. During his lifetime, Priestley's considerable scientific reputation rested on his invention of carbonated water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen). Priestley's determination to defend phlogiston theory and to reject what would become the chemical revolution eventually left him isolated within the scientific community. (Full article...)

Little Fishing Creek looking downstream in Millville

Little Fishing Creek is a tributary of Fishing Creek in Sullivan County, Lycoming County, and Columbia County, in Pennsylvania, in the United States. It is approximately 23.5 miles (37.8 km) long and flows through eight townships. The watershed of the creek has an area of 68.1 square miles (176 km2). The creek has six named tributaries, of which the largest are Spruce Run and West Branch Run.

There are at least two major rock formations in the watershed of Little Fishing Creek: the Chemung Formation and the Hamilton Group. The creek's watershed includes part of the Greenwood Valley. Much of the watershed is forested and major roads in it include Pennsylvania Route 42. The first European settler first arrived in the vicinity of the creek during the 1760s or 1770s, with other settlers arriving in the 1790s. A number of sawmills, woolen mills, and tanneries historically operated on the creek. A number of covered bridges have also been built over it and there were historically some railroads in the watershed. (Full article...)

The Fishing Creek Confederacy took place in the vicinity of Fishing Creek

The Fishing Creek Confederacy was a military uprising in northern Columbia County, Pennsylvania and southern Sullivan County, Pennsylvania during the American Civil War. Residents of Columbia County strongly opposed military drafts that were being conducted there, leading to widespread desertion and draft evasion. In a Columbia County draft in July 1863, 618 people were drafted. Of these, approximately 75% evaded the draft. On July 30, 1864, several people rode into northern Columbia County from Luzerne County to search for deserters, and one of the riders was shot. By the summer of 1864, rumors had begun to circulate that these deserters and draft evaders, as well as Confederate sympathizers, had built a fort with cannons on North Mountain, not far from the headwaters of Fishing Creek. This fort was supposedly manned by 500 people. Upon hearing these rumors, 1000 soldiers gathered near Bloomsburg, in Columbia County.

On August 21, 1864, the soldiers began traveling up Fishing Creek. For the next week, they searched the northern portion of Columbia County for deserters and draft evaders. They were unable to find any, but on August 28 they arrested 100 local citizens. Most were released, although some were taken to Fort Mifflin. The soldiers continued heading into the northernmost reaches of the Fishing Creek watershed. Unable to find any evidence of a conspiracy, they returned to Bloomsburg and remained in the county until December 1864. The last of the prisoners were released from Fort Mifflin several months after their arrest. (Full article...)

The Carlisle Indian School logo

The United States Indian Industrial School in Carlisle, Pennsylvania, generally known as Carlisle Indian Industrial School, was the flagship Indian boarding school in the United States from its founding in 1879 to 1918. It was based in the historic Carlisle Barracks, which was transferred to the Department of Interior from the War Department for the purpose of establishing the school. Throughout its history, over 7,800 children from 140 Native American tribes were enrolled at the school. After the United States entered World War I, the school was closed, and the property was transferred back for use by the U.S. Department of Defense. The property is now part of the U.S. Army War College.

In December 2024, it was designated a national monument by President Joe Biden called the Carlisle Federal Indian Boarding School National Monument and co-managed by the Army and the National Park Service in consultation with Native American tribes. (Full article...)
