Why did Parliament implement the policies that it did with regard to the colonies in the 1760s and 1770s?
Parliament implemented these sorts of policies largely because it needed more money. It had spent a tremendous amount of money on the Seven Years' War and needed to recoup some of that. Because of this, Parliament did two main things. First, it imposed various taxes on the colonies to get money from them. Second, it did various things to tighten British control of the colonies. It did things like setting up courts to try colonists who were smuggling and who had not been strongly prosecuted by the colonial authorities. This, too, would ensure that the colonial economies did more to benefit Britain than they had previously.
One of the main issues was that Britain was in debt so they needed to increase their revenue so they made internal and external taxes like the Stamp Act and the Sugar Act.
