What contributed to the growth of representatives self government and democracy in the 13 colonies

There are three reasons for the growth of representative self-government in the 13 colonies. One of them is the population growth: this allowed cities to be formed and at the same time centers of government appeared. Another reason is the development of an independent economy: this allowed some colonies to issue their own money. And last but not least, the attempts of the British to control and dominate their colonies: this made the colonies to really want to have a self-government and their citizens to decide who they want to rule over them.
