After winning the Seven Years? War, the Americans believed that they had the right to settle west of the Appalachians after paying with their blood that war. Since Parliament had passed the Proclamation of 1763, the Americans were dismayed and angered by seeing this as another form of oppression and proudly defied it by crossing over. The colonists were further provoked to rebel as they fiercely resented the Privy council's usage of the royal veto on reforms they deemed desirable. Lastly, the colonies felt that they were being used by the mercantile system because they were not at liberty to buy, sell, ship, or manufacture under profitable conditions. They became restless and welcomed the opportunity to end their bond with Britain to get out of debt. No matter how hard Britain tried to limit their civil liberties, the colonists were quick to anger and rebelled with opposition.
The next factor that caused the Americans to rebel was due to Britain's foolish military measures in the colonies. One of the first mistakes occurred when the Quartering Act was passed to force certain colonies to provide food and quarters for British troops. Resentment kept burning over this act especially after New York's legislature was suspended for failure to comply. Another military measure that caused resentment was Britain's decision to bring troops to Boston to stop smuggling of tea and to restore order. In return the colonists who resented their presence fought a squad of ten redcoats who were armed, resulting in eleven citizens getting hurt. Both sides remained bitter to each other so the first local committees of correspondence in Boston spread propaganda to keep alive the opposition of Britain. In 1775 a British commander made the final mistake to seize supplies and to capture rebel leaders at nearby Lexington and Concord. "The shot heard around the world" occurred in this battle, as colonial minutemen showed no mercy, proving to England that they wouldn't take any control from them anymore.
