William Penn wanted the Pennsylvania colony for the Quakers. The Quakers are known to be part of a historical Christian cluster back in the day, wherein it is part of a religious movements, which is known as the Religious Society of Friends, or it can be referred to as Friends Church.
Penn was the founder of the province of Pennsylvania, a colony of the United Kingdom that later would become the homonymous American state. The democratic principles he implemented in the colony served as a source of inspiration for the American Constitution.
William Penn was a Quaker and he founded the American Commonwealth of Pennsylvania in order to create a refuge for Quakers (but not only them, also other religious minorities from Europe).
Many Europeans had experienced the tyranny of monarchies in their own countries. The Patriots' war against George III inspired them. Lafayette and Pulaski may have also been moved by the ideas in the declaration of Independence. I hope this helps you
