Final answer:
The Mayflower Compact signers agreed to create and follow a self-governed social contract to maintain order, which lasted until Plymouth Colony merged with the Massachusetts Bay Colony in 1692.
Step-by-step explanation:
The signers of the Mayflower Compact agreed to form a government by social contract and pledged to uphold a social order by obeying the laws for the good of the colony. Since they landed outside the jurisdiction of the Virginia Company, with no charter to govern them, they established self-rule through the Compact. It not only bound them to a common purpose but also set a precedent for self-governance, operating until 1692 when Plymouth Colony merged with the Massachusetts Bay Colony.
