Final answer:
The Jamestown colonists set a political precedent by forming the General Assembly, the first legislative assembly in the New World that addressed key issues and established early democratic principles.
Step-by-step explanation:
The Jamestown colonists set a political precedent by establishing what is known as the General Assembly, the first elected legislative assembly in the New World, which held its first meeting in 1619. This unicameral session, composed of the Governor, the Governor's Council, and burgesses, tackled issues like tobacco prices, indentured servants, and Indian relations. Such an assembly laid the foundation for future democratic practices in the colonies and eventually the United States.
