How did great britain increase its control over the colonies

Great Britain increased its control over the colonies by creating various of acts on the colonists.  As such they placed taxes (a.k.a Custom Duties and Tariffs: any tax on imported and exported goods) on certain things. An example of the most known act was the Tea Act. The Tea Act was to tax any tea items. Because the colonists were getting taxed so much before the Tea Act, the Boston Massacre occurred where the colonists disguised themselves, boarding the ship and dumping chests of tea into the water. Thus, Britain created the Coercive Act, preventing the actions of colonists and banning the Massachusetts's port until they paid for it, expanding their powers.
