The Mayflower Compact was the first governing document of Plymouth Colony. It was written by the Separatists, also known as the "Saints", fleeing religious persecution from James VI and I. They traveled aboard the Mayflower in 1620 along with adventurers, tradesmen, and servants, most of whom were referred to as "Strangers".

The Mayflower Compact was signed on November 11, 1620 (OS), by 41 of the ship's 101 passengers, while the Mayflower was anchored in what is now Provincetown Harbor within the hook at the northern tip of Cape Cod.

The Mayflower was originally bound for the mouth of the Hudson River, in land granted in a patent from the Crown to the London Virginia Company. The decision was made instead to land farther north, in what is now Massachusetts. This inspired some of the "strangers" (colonists who were not members of the congregation of religious dissenters leading the expedition) to proclaim that since the settlement would not be made in the agreed-upon Virginia territory, they "would use their own liberty; for none had power to command them...." To prevent this, many of the other colonists decided to establish a government. The Mayflower Compact was based simultaneously upon a majoritarian model (even though the signers were not in the majority) and the settlers' allegiance to the king. It was in essence a social contract in which the settlers consented to follow the compact's rules and regulations for the sake of survival.
