The term 'Quaker Colonist' refers to William Penn, a Quaker leader who founded the Province of Pennsylvania in 1681. Penn was granted a charter from King Charles II of England, which allowed him to establish a colony in the New World. Penn's colony was based on the principles of religious freedom and tolerance, and it became a haven for persecuted Quakers and other religious minorities. Penn's colony was also known for its progressive laws, including the abolition of slavery. Penn's legacy as a Quaker colonist is still remembered today.
