What term describes Pennsylvania's founding as a haven for Quakers and others seeking to promote liberal ideas?

The term "Holy Experiment" accurately describes Pennsylvania's founding as a place for Quakers and others seeking to promote liberal ideas. This phrase was coined by William Penn, the founder of Pennsylvania, to characterize his vision for the colony as a refuge promoting religious tolerance and freedom. Penn sought to create a society where people of diverse faiths and backgrounds could coexist peacefully, thus embodying the principles of liberty and equality. The "Holy Experiment" emphasized the Quaker values of simplicity, peace, and integrity, reflecting a broader Enlightenment ethos that embraced reason and individual rights.

In contrast, the other terms do not encapsulate the specific historical and ideological intentions behind Pennsylvania's establishment. While "Social Refuge" could imply a space for people seeking safety or community, it lacks the religious and philosophical connotations attached to "Holy Experiment." "Liberty Foundation" and "Quaker Colony" are also too general or narrowly focused, failing to capture the full essence of Penn's vision of a democratic and pluralistic society. Thus, "Holy Experiment" is the most fitting description of the founding ideals of Pennsylvania.
