Pennsylvania holds an important place in the story of the United States. One of the original 13 colonies and with both the Declaration of Independence and U.S. Constitution having been signed in Philadelphia. The state has a rich industrial heritage with the region’s coal and iron resources helping to fuel the country's growth.

It has provided the foundations for a strong modern-day economy which has grown and diversified to become the sixth largest GDP in the U.S. In recent years, the state has become an important center for healthcare, education, and tourism with millions of visitors attracted to the state’s historical sites.

Rich in historic lore, Pennsylvania territory was disputed in the early 1600s among the Dutch, the Swedes, and the English. England acquired the region in 1664 with the capture of New York, and in 1681 Pennsylvania was granted to William Penn, a Quaker, by King Charles II.

Philadelphia was the seat of the federal government almost continuously from 1776 to 1800; there the Declaration of Independence was signed in 1776 and the U.S. Constitution was drawn up in 1787. Revolutionary War fame, and Gettysburg, site of the pivotal battle of the Civil War, are both in Pennsylvania. The Liberty Bell is located in a glass pavilion across from Independence Hall in Philadelphia.

The nation's first oil well was dug at Titusville in 1859, and the mining of iron ore and coal led to the development of the state's steel industry. More recently Pennsylvania's industry has diversified, although the state still leads the country in the production of specialty steel. The service, retail trade, and manufacturing sectors provide the most jobs; Pennsylvania is a leader in the production of chemicals and pharmaceuticals, food products, and electronic equipment.

Counties are responsible for services such as law enforcement, elections, and maintenance of public records.

The municipalities are divided into boroughs and townships. Boroughs are smaller, more urban municipalities, while townships are more rural in nature. School districts are separate entities from the counties and municipalities and are responsible for the operation of public schools within their boundaries.

The Commonwealth of Pennsylvania has around 500 public school districts with enrolment mandatory for minors from the age of 8. There are also thousands of private schools and publicly funded colleges, graduate schools, universities, and over 100 private institutions of higher education.

The Commonwealth System of Higher Education consists of four universities, which are publicly supported but operated and controlled independently. These institutions are Lincoln University, Pennsylvania State University, Temple University, and the University of Pittsburgh.

The University of Pennsylvania in Philadelphia is a private research university and a member of the Ivy League. Also known as Penn or UPenn, it is the fourth-oldest higher education institution in the United States.

Pennsylvania State Economy

The economy of Pennsylvania has undergone some significant changes throughout its history. The economy was formerly based on heavy industry and manufacturing, particularly in the production of steel and coal. In recent decades, the state has had to make the transition towards a more service-based economy.

According to the Bureau of Economic Analysis, the state's gross domestic product (GDP) was $839.4 billion in 2021, making it the sixth largest in the U.S. The state's unemployment rate was 4.1% in November 2020, slightly lower than the national average of 6.0%.

The state is home to a number of major corporations in industries such as healthcare, finance, and technology. It is a major producer of agricultural products, particularly dairy, poultry, and apples. Pennsylvania is also a leading producer of energy supplies with coal reserves and natural gas found in the Marcellus Shale formation.

Major sectors include healthcare, education, and manufacturing. Manufacturing within Pennsylvania includes the production of goods such as machinery, chemicals, and food products, employing around 10% of the state's workforce.

Pennsylvania's economy continues to evolve and adapt to changing economic conditions. The state's industrial heritage has laid a solid foundation for a diverse and resilient economy that continues to drive growth.

Pennsylvania State Interesting Facts

Pennsylvania's 63,200 farms (occupying nearly 8 million acres) are the backbone of the state's economy, producing a wide variety of crops. Leading commodities are dairy products, corn, cattle and calves, mushrooms, poultry and eggs, a variety of fruits, sweet corn, potatoes, maple syrup, and Christmas trees.

Pennsylvania's rich heritage draws billions of tourist dollars annually. Among the chief attractions are the Gettysburg National Military Park, Valley Forge National Historical Park, Independence National Historical Park in Philadelphia, the Pennsylvania Dutch region, the Eisenhower farm near Gettysburg, and the Delaware Water Gap National Recreation Area.

Pennsylvania is mostly known for its pivotal role in American history and its heritage as an industrial powerhouse that supplied much of the coal and steel that built the American infrastructure. According to a 2022 YouGov survey, Pennsylvania is the fifth most visited state with 48% of Americans having been there.

Liberty Bell

The Liberty Bell is one of the country’s most famous historical objects and has become an icon of American Independence. The copper bell was commissioned in 1752 and cast by the Lester and Pack company in London. It features an inscription which is taken from the Bible that states: “Proclaim LIBERTY Throughout all the Land unto all the Inhabitants Thereof“.

The bell was originally placed in the steeple of the Pennsylvania State House which is now known as Independence Hall. It was used to lawmakers to court sessions and to alert citizens when public meetings were being held.

It’s believed that the bell was rung on July 4, 1776, to celebrate the reading of the United States Declaration of Independence. It was in the 1830s that the bell started to become a symbol and became dubbed the ‘Liberty Bell’.

It was also during this time that the bell developed a distinctive crack. During the 1880s the bell toured throughout the Philadelphia area with large crowds gathering at patriotic events.

Liberty Bell was moved to a glass pavilion near to Independence Hall in 2003 and continues to be one of the state’s most popular tourist attractions and a recognized symbol of American freedom.

Steel Heritage

Pennsylvania was once home to the two largest steel producers in the world the US Steel company in Pittsburgh and Bethlehem Steel in Bethlehem. The industry brought vast wealth to the steel owners with Andrew Carnegie, an immigrant from Scotland, becoming one of the richest people in the world.

Steel from Pennsylvania was used to build much of the nation’s infrastructure as America was starting to develop as an industrial powerhouse. It was used to build structures such as the Empire State and Chrysler Building in New York, as well as a giant Ferris wheel in Chicago.

While the steel industry has significantly reduced in recent times, the state continues to be a major producer, and Pennsylvania’s industrial past lives on through the name of the NFL franchise, the Pittsburgh Steelers.

Amish Communities

Pennsylvania is the US state with the largest population of Amish people. The arrival of Amish communities in the US dates back to the 18th century when various Anabaptist groups were escaping from the Reformation taking place in much of Europe.

The Amish were the most conservative of these groups with strict rules and a rejection of many aspects of the secular world. Many of the Amish living in Pennsylvania insulate themselves from many aspects of modern society such as technology and mass media.

The largest Amish community in the world exists in Lancaster Country with around 30,000 people and around 300 church districts. Visits to Amish communities have become an increasingly popular activity for visitors to the county with tours and Amish-run guest houses.

Pennsylvania State History

Pennsylvania has played a crucial role in the emergence of the United States. The state was one of the original 13 colonies and played a prominent role in the American Revolution. Philadelphia, the state's largest city, has served as the nation's capital and both The Declaration of Independence and the U.S. Constitution were signed in the city of Philadelphia. Here’s an overview of the history of Pennsylvania.

Pre-Colonial Times

Before the arrival of European settlers in the 17th century, the region that is now known as Pennsylvania was home to several Native American tribes. The Lenape, who spoke an Algonquian language, were the most prevalent in the southeastern portion of the state, while the Iroquois controlled the western and central regions. The Susquehannock people inhabited the southern tier of counties and parts of the lower Susquehanna River valley. The Eries, Andastes, and Shawnees also had settlements in the state, while the Minquas were the dominant tribe in the northern and central portions of the state.

Colonial History

In the early 17th century, the Dutch and Swedish established settlements in the region, but it was the British who would ultimately claim the land for their own. William Penn, a Quaker, was granted a charter for the land that would become Pennsylvania in 1681. The province’s first assembly took place in Chester, named after the English town of Chester.

Penn established Philadelphia the following year, which quickly became a center for trade and commerce. Penn also established a system of government that allowed for religious freedom, which attracted a diverse group of settlers to the colony, including Germans, Scotch-Irish, and English Quakers. The colony also had a substantial number of enslaved African Americans in the colonial period, particularly in the region of southeastern Pennsylvania and in cities like Philadelphia.

After the death of William Penn in 1718, he was succeeded by his sons. The peaceful relations with the Native American communities started to deteriorate with increasing conflict. Pennsylvania became involved in the Pontiac’s Rebellion of 1762 when a coalition of Native Americans attempted to drive the British out of the region. After the failure of this rebellion, the Native Americans posed no significant threat to the European settlers.

Pennsylvania was one of the 13 colonies that protested against British rule following the Stamp Act of 1763. In 1765, Philadelphia hosted delegates for meetings which led to the signing of the Declaration of Independence in 1776. Following this, Pennsylvania became the site for numerous battles with the British during the American Revolution.

During the war, Philadelphia acted as the capital of the emerging nation and served another temporary spell as the capital between 1790 and 1800.

American Civil War

During the American Civil War, Pennsylvania was a key state for the Union cause. It was home to several major battles, including the Battle of Gettysburg, which is considered a turning point in the war and one of the bloodiest battles fought on American soil. Other smaller skirmishes fought in the state included the battles of Hanover, Hunterstown, Carlisle, and Fairfield.

Pennsylvania also played an important role in the war effort, with its industries supplying the Union army with weapons, uniforms, and supplies. Additionally, many Pennsylvanians fought in the war, with around 350,000 men enlisting in the Union ranks.

Post-Civil War

After the Civil War, Pennsylvania underwent a period of rapid industrialization, with new factories and mines being established throughout the state. The state became home to some of the world’s largest steel providers with two of the main players being Carnegie Steel Company and Bethlehem Steel.

The growth of the industry led to steel owners such as Andrew Carnegie acquiring immense wealth. Industry also helped to draw large numbers of immigrants, particularly from Europe, who came to work in the steelworks and collieries. In the late 19th century and early 20th century, Pennsylvania was home to a growing labor movement, with many workers organizing to demand better working conditions and higher wages.

Two of the prominent union conflicts were the Great Railroad Strike of 1877 and the Coal Strike of 1902. The harsh conditions experienced during the Great Depression in the 1930s changed the political makeup of the state with a shift from Republican to Democrat support.

Modern History

In the post-World War II era, Pennsylvania continued to be an important center for industry and commerce. However, the state's economy has diversified greatly with the growth of service industries and technology companies. Pennsylvania has also played a significant role in national politics, with several notable political figures hailing from the state, such as James Buchanan, the only president from Pennsylvania, and Tom Ridge, the first Secretary of Homeland Security.

The state has also seen a shift in its demographics and population distribution over the years with a more diverse population moving from rural to urban areas. Pennsylvania has been active in recent years on issues such as fracking, wind power, and alternative energy sources.

With the first cases reported in March 2020, Pennsylvania recorded the six-highest number of infections during the coronavirus pandemic. As of 2021, the Pennsylvania Department of Health confirmed 1,464,264 cases and 29,814 deaths.
