We have had two wars with Britian, the American Revolution and the War of 1812. The American Revolution had many causes including taxes without corresponding representation in the British Parliament. Also resentment of the Quartering of British soldiers in colonist homes, the Boston Massacre, and the British punishment of Boston for the Boston Tea party. The War of 1812 was fought because the British were kidnapping American sailors off of American ships, and the British provoking Indians to attack Americans.
