What is the importance in american history of the mayflower compact?

The Mayflower Compact was the first agreement for self-government to be created and enforced in America. On September 16, 1620 the Mayflower, a British ship, with 102 passengers, who called themselves Pilgrims, aboard sailed from Plymouth, England. They were bound for the New World. Hope this helped!!

The articles created a national government composed of a congress, which had the power to declare war, sign treaties, make alliances and more.
