The Province of Pennsylvania, also known as the Pennsylvania Colony, was founded in English North America by William Penn on March 4, 1681 as dictated in a royal charter granted by King Charles II. The name Pennsylvania, which translates roughly as "Penn's Woods", was created by combining the Penn surname (in honor of William's father, Admiral Sir William Penn) with the Latin word sylvania, meaning "forest land." The Province of Pennsylvania was one of the two major Restoration colonies, the other being the Province of Carolina. The proprietary colony's charter remained in the hands of the Penn family until the American Revolution, when the Commonwealth of Pennsylvania was created and became one of the original thirteen states.

The colonial government, established in 1683 by Penn's Frame of Government, consisted of an appointed Governor, the proprietor (William Penn), a 72-member Provincial Council, and a larger General Assembly. The General Assembly, also known as the Pennsylvania Provincial Assembly, was the largest and most representative branch of government, but had little power.

Succeeding Frames of Government, also known as the Charter of Privileges, were produced in 1683, 1696 and 1701. The fourth Frame (Charter of Privileges) remained in effect until the American Revolution. At that time, the Provincial Assembly was deemed too moderate by the revolutionaries, who ignored the Assembly and held a convention which produced the Constitution of 1776 for the newly established Commonwealth of Pennsylvania, creating a new General Assembly in the process.
