The Mayflower Compact was the first governing document of Plymouth Colony. It was written by separatist Congregationalists who called themselves "Saints". Later they were referred to as Pilgrims or Pilgrim Fathers. They were fleeing from religious persecution by King James of England. They traveled aboard the Mayflower in 1620 along with adventurers, tradesmen, and servants, most of whom were referred to by the Separatists as "Strangers".
