Since Plymouth did not have an official charter from England its government was based on which document?

Plymouth's government was based on the Mayflower Compact, a document signed by the Pilgrims in 1620 aboard the Mayflower. This compact established a framework for self-governance and mutual agreement among the settlers, emphasizing the principles of majority rule and cooperation for the common good. Though not an official charter from England, it served as an important foundation for governance in the Plymouth Colony.
