The navigation acts, the Enlightenment, and the Great Awakening on the colonists, were events that, although different among themselves, achieved the union of all the colonies, something that would be the precursor of the War of Independence.

The British ministers were a higher class, but the ministers of the Great Awakening could break the rules; the new beliefs were also much more democratic and their message was of equality; also the first important event in which all the colonies could participate. They were both points of union for the 13 colonies.
