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

The term that describes Pennsylvania's founding as a haven for Quakers and others seeking to promote liberal ideas is "Holy Experiment." This phrase, coined by William Penn, the founder of Pennsylvania, reflects his vision of establishing a colony where religious freedom and tolerance could flourish. Penn intended to create a community that welcomed diverse beliefs, allowing for a harmonious coexistence among different religious and ethnic groups. The Holy Experiment was not merely about providing refuge for Quakers; it represented an ambitious social and political experiment in democracy and egalitarianism, which was quite progressive for the time.

In the context of early American history, the notion of a colony as a "Holy Experiment" underscores Pennsylvania's unique position as a model for religious tolerance and liberal governance, contrasting with the more rigidly sectarian and hierarchical structures found in some of the other colonies. It highlights Pennsylvania's role in shaping ideas about religious freedom and the rights of individuals to express their beliefs in a supportive environment.
