The Mayflower Compact was important because it was the first document to establish self-government in the New World. It remained active until 1691 when Plymouth Colony became part of Massachusetts Bay Colony.
The Mayflower Compact was an early, successful attempt at democracy and undoubtedly played a role in future colonists seeking permanent independence from British rule and shaping the nation that eventually became the United States of America.
There were arguments among the 102 Mayflower passengers as to whether the compact should be rewritten when they landed on Plymouth Rock rather than the northern part of Virginia as originally planned. It was somewhat amended as to locations noted, but the point remained: They – from Great Britain, France and Ireland – started their journey "for the Glory of God, and advancements of the Christian faith …"
It was over a year later – in 1621 – that the Pilgrims and native Americans together celebrated the First Thanksgiving.
The full text of the Mayflower Compact is as follows:
In the name of God, Amen. We, whose names are underwritten, the Loyal Subjects of our dread Sovereign Lord King James, by the Grace of God, of Great Britain, France, and Ireland, King, defender of the Faith, etc.:
Having undertaken, for the Glory of God, and advancements of the Christian faith, and the honor of our King and Country, a voyage to plant the first colony in the Northern parts of Virginia; do by these presents, solemnly and mutually, in the presence of God, and one another; covenant and combine ourselves together into a civil body politic; for our better ordering, and preservation and furtherance of the ends aforesaid; and by virtue hereof to enact, constitute, and frame, such just and equal laws, ordinances, acts, constitutions, and offices, from time to time, as shall be thought most meet and convenient for the general good of the colony; unto which we promise all due submission and obedience.
