In what year was the Mayflower Compact signed?

The Mayflower Compact was signed in 1620, which was a pivotal moment in early American history. This document was created and agreed upon by the Pilgrims aboard the Mayflower, shortly before they landed at Plymouth Rock. The Compact served as a social contract in which the settlers consented to form a government and abide by its laws, reflecting their commitment to a cooperative society based on majority rule.

This year is significant not only for the establishment of governance among the settlers but also for its role in laying the groundwork for future democratic principles in the United States. The choices of 1617, 1619, and 1621 do not reflect the correct timeline of events related to the Mayflower's voyage and landing in the New World. The Compact is specifically tied to the events of the Pilgrims' arrival in 1620, thus making this year the correct answer.
