Why is the mayflower compact noteworthy?

The Mayflower Compact is noteworthy because it was the first document that was formulated to establish a self-government in the New World. It set the rules on how the Pilgrims and non-Pilgrims were to conduct their lives so that there would be peace and harmony in the new colony. 

A representative government is a type of government in which the citizens vote to elect people that would represent them. This means that the elected people will listen to their concerns and act in accordance to them. This is the type of government that was established in the colonies after Independence. Therefore, the sentence could be something like this:

"Because the colonists did not feel that their interests were represented in the English government, they decided to establish their own representative government."
