Pennsylvania

**Pennsylvania** is one of the 50 states in the United States of America. It is in the northeastern part of the country. It has a border with the Canadian province of Ontario on the north, Ohio on the west, West Virginia on the south and west, Maryland and Delaware on the south, New Jersey on the east, and New York and Lake Erie on the north. Pennsylvania is divided into 67 counties.

The state capital of Pennsylvania is Harrisburg. The largest city in Pennsylvania is Philadelphia. The state nickname of Pennsylvania is, "The Keystone State". The current governor of Pennsylvania is Josh Shapiro.

Pennsylvania is well known for its role in the American Revolution, its large communities of Amish, and its heavy industry.

## History
Pennsylvania was home to many Native American groups before Europeans settled there. These include the Delaware, Susquehanna, and Iroquois. Pennsylvania was founded in 1681 through a royal land grant given to William Penn by King Charles II.

The first European settlers in Pennsylvania were from Sweden. They arrived in 1643. The area was later ruled by the Netherlands and Great Britain. In 1681, Charles II of England, gave the land to William Penn. Penn used the land to create a home for Quakers. The land became known as "Penn's Woods", as Pennsylvania has many forests. In Latin this is "Pennsylvania". This became adopted as the name of the colony. 

The state of Delaware was once part of Pennsylvania. In 1704, Delaware formed when three Pennsylvania counties left the colony and created their own government.

Pennsylvania was one of the 13 colonies that fought Great Britain in the American Revolution. The United States Declaration of Independence was signed in Philadelphia. Benjamin Franklin, an important figure in the Revolution, was also from Philadelphia. Pennsylvania was the second state to join the United States. Philadelphia was capital of the United States before Washington, D.C..

Later, Pennsylvania became an important center of industry. Kerosene was discovered in Titusville in the 19th century. This was the start of the oil industry in the United States. Large deposits of coal were found in and around Pittsburgh. This caused Pittsburgh to become a major industrial city. Pennsylvania was the location of two hugely prominent strikes, the Great Railroad Strike of 1877 and the Coal Strike of 1902. The eight-hour day was eventually adopted, and the coal and iron police were banned.

Industry began leaving Pennsylvania in the late 20th century, because most heavy industry was being transferred to other nations. Many people left, too. It also caused many of its cities and towns to decay.

In 1923, President Calvin Coolidge established the Allegheny National Forest under the authority of the Weeks Act of 1911.

## Geography
Most of Pennsylvania is part of the Appalachian Mountains, including the south central and northeastern areas of the state. Much of the rest of the state is very hilly, partly due to the closeness to mountains and partly due to the steep river valleys in the state. The Monongahela, Allegheny, and Ohio rivers are in the western part of the state, and the Susquehanna is in the central part of the state. The northwestern and southeastern parts of the state are mostly flat and low-lying.

More than half of the people live in the areas of Pittsburgh and Philadelphia. Few people live in the north central area of the state. Towns and cities tend to be small in size and densely populated, more so than in other states. This is because many of the towns and cities in Pennsylvania were built around a specific factory or factories.

Other significant private universities are Carnegie-Mellon University, known for its computer science research, and Bucknell University.
