Answer:
The Plymouth Colony was founded by Pilgrims aboard the Mayflower in 1620.
Step-by-step explanation:
The Plymouth Colony was an English colony that existed from 1620 to 1691 in the southeast of the modern state of Massachusetts.
The legal foundation of the colony was the agreement concluded on board of the Mayflower. Founded by deeply religious people, the Plymouth colony was distinguished by Puritan mores and adherence to traditions. Some of them have become an integral part of American culture. Among these is the custom to celebrate Thanksgiving (first celebrated by the pilgrims in New Plymouth in 1621).
In 1691, the Plymouth colony was merged with the Massachusetts Bay colony and the Maine colony to form the province of Massachusetts.
