Which important event took place in 1620?

In 1620, the establishment of Plymouth Colony marked a significant moment in early American history. This event was crucial as it represented one of the first successful colonies founded by English settlers in North America. The Pilgrims, who were seeking religious freedom, traveled aboard the Mayflower and arrived at what is now Massachusetts. They drafted the Mayflower Compact, an early form of self-governance that set a precedent for future democratic practices in the colonies.

The other events listed occurred during different time periods: the signing of the Magna Carta took place in 1215, laying foundational principles for modern democracy; the beginning of the American Revolution was in 1775, as tensions escalated between the American colonies and British rule; and the ratification of the Constitution happened in 1788, establishing the framework for the national government. Each of these events is important in its own right but does not relate to the year 1620.
