1) Conflict over taxation- American colonists complained about the fact that the British parliament was able to implement taxes in the colonies during this time. Before the French and Indian War, this power was given solely to the colonial legislature which the colonists got to pick. After the debt incurred by the British in the French and Indian War, this policy changed so that the colonists could help pay off the debt from this war.
2) Conflict over representation- Colonists felt that it was unfair that the British parliament got to pass laws/taxes for them without having a representative their to express the views/concerns of the colonists.
3) Conflict over tea- The Tea Act, which gave the British East India Company a monopoly in the colonies, upset the colonists because it limited where they could buy their tea. This resulted in the Boston Tea Party, in which colonists destroyed British tea by dumping it into the Boston Harbor.
4) Conflict over military- Thanks to the Intolerable Acts, the colonists were now forced to house British soldiers at any given time. The colonists felt that this was a huge infringement on their personal freedom and rights.
