List of Major American Wars
The British Navigation acts, the closing of western lands, the restricting of the colonial currency, the Quartering Act, the Stamp Act, and The Townshend Acts enacted by the British Parliament contributed to the revolution of colonists. In 1773, the British Parliament permitted the East India Company to sell tea in the colonies at very low prices, which resulted in the Boston tea party. The response of the British Parliament was the Intolerable Acts and the Quebec Act in 1774. In September of the same year, the First Continental Congress was held in Philadelphia. The Revolutionary War began in 1775. The second Continental Congress was held in May, 1775 in Philadelphia. In 1776, the United States declared independence. British and American troops fought near Boston, New York, Trenton, and other places. In 1783, by the Treaty of Paris, the independence of the 13th colonies was recognized by Great Britain, and the war ended.
