The American Colonists wanted to be free of British Rule, because they believed that the British had no right to raise taxes on them and impose unneeded protection (which means more taxes). They didn't like it when there were more British soldiers, and that they had to quarter them (Quartering Act), and that they were getting taxed on everything (stamp act, tea act, etc). The Americans demanded change, or else they would split, but the British didn't listen. This resulted in riots, and when a group of british soldiers shot into a crowd of protesting colonists, it was the last straw, and the spark of the Revolutionary war
hope this helps
