William Penn referred to his colony as a “Holy Experiment” because  its degree of religious tolerance had never been tried before.

The Holy Experiment was the realization of a project of political organization that was based on a religious concept of tolerance. It was an attempt by the Quakers (led by William Penn) to establish a community for themselves in Pennsylvania. They hoped to show the world how well they could operate on their own without any kind of persecution or dissension. It was maintained during the period of 1681, the year of the foundation of the Colony of Pennsylvania by the Quakers, until 1756, the year in which they withdrew from the government.

it was the "4. potsdam" conference that demanded the unconditional surrender of japan, since it was clear that the japanese would continue to find until the very last man otherwise.
