Final answer:
The Society of Friends, founded by George Fox and commonly known as Quakers, believed in the equality of all people and rejected social hierarchy and warfare.
Step-by-step explanation:
George Fox established a new denomination of Christianity called The Society of Friends, or the Quakers. These people believed that all people were equal. They also did not believe in social hierarchy or warfare. This made them unpopular in Europe where social classes were a way of life. Nobility expected to be treated differently than everyone else; something Quakers would not do.
