What promise was made by the signers of the Mayflower Compact? They promised to pass laws for the general good of the colony.
They promised to give everybody an equal say in government.
They promised to establish the House of Burgesses.
They promised to always set a positive example for all people.

They promised to pass laws for the general good of the colony.

Explanation:

The colonists had no intention of declaring their independence from England when they signed the Mayflower Compact. In the opening line of the Compact, both Pilgrims and "Strangers" refer to themselves as "loyal subjects" of King James. The rest of the Mayflower Compact is very short. It simply bound the signers into a "Civil Body Politic" for the purpose of passing "just and equal Laws . . . for the general good of the Colony."
