William Penn

Motivation for Founding

Part of present-day Pennsylvania was actually included in the territory named New Sweden that had been founded by Swedish settlers in 1638. This territory was then surrendered to the Dutch in 1655 when Peter Stuyvesant sent a large force to invade. Swedes and Finns continued to arrive and settle in what would become Pennsylvania. 

In 1681, William Penn, a Quaker, was given a land grant from King Charles II who owed money to Penn's deceased Father.

Immediately, Penn sent his cousin William Markham to the territory to take control of it and be its governor. Penn's goal with Pennsylvania was to create a colony that allowed for freedom of religion due to his desire to protect himself and fellow Quakers from persecution.

Arrival of William Penn

In 1682, William Penn arrived in Pennsylvania on a ship called the Welcome. He quickly instituted the First Frame of Government and created three counties: Philadelphia, Chester, and Bucks. When he called a General Assembly to meet in Chester, it called for the Delaware counties to be joined with those of Pennsylvania and the Governor to preside over both areas. It won't be until 1703 that Delaware will separate itself from Pennsylvania. In addition, the General Assembly adopted the Great Law which provided for the liberty of conscience in terms of religious affiliations. 

By 1683, the Second General Assembly created the Second Frame of Government.

Any Swedish settlers were to become English subjects seeing that the English were now in a majority in the colony. 

Pennsylvania During the American Revolution 

Pennsylvania played an extremely important role in the American Revolution. The First and Second Continental Congresses were convened in Philadelphia.

This is where the Declaration of Independence was written and signed. Numerous key battles and events of the war occurred in the colony including the crossing of the Delaware, the Battle of Brandywine, the Battle of Germantown, and the winter encampment at Valley Forge. The Articles of Confederation were also drafted in Pennsylvania, the document that would form the basis of the new Confederation that resulted at the end of the Revolutionary War.
