The document summarizes five main causes of the American Revolution: 1) The Proclamation of 1763 restricted colonial settlement beyond the Appalachian Mountains, frustrating settlers. 2) The Boston Tea Party was an act of rebellion where colonists dumped British tea into the harbor. 3) The Stamp Act of 1764 directly taxed the colonies for the first time without representation. 4) The Boston Massacre killed and injured colonists when British soldiers fired into a crowd. 5) The French and Indian War led to increased British control and taxation in America, fueling tensions.
