The Mayflower Compact: Contributed to the development of representative Democracy in the States.
The founding of Rhode Island: Contributed to the separation of church and state, practicing religious tolerance.
The Salem Witch Trials: Contributed to changes in U.S. court procedures, including rights to legal representation and cross-examination of accusers
