And with the development of economy, the people in the colonies wanted more power to determine their business. But the policy of the British Government was to bring the development under their control and collect more taxes from the colonies.In order to finance a large army stationed in America, the British Government collected more money from the colonies and requited回报the colonies to provide the troops with fuel, light, bedding and other things.The East India Company, a vital source of British wealth, was in financial straits. To help the company turn the corner, the British Government granted it the monopoly垄断over all the tea exported to the colonies without paying duty .Thus the company could easily undersell the independent tea merchants and the smugglers in the colonies, who organized strong opposition to this unequal treatment.Boston Tea PartyOn the might of December 16, 1773, a band of men, disguised as Indians and led by Samuel Adams, boarded three British ships lying at anchor in Boston and dumped their tea cargo, which was from China, into the sea. 342 chest of tea valued at about ﹩75,000 were thus destroyed.

It had been proposed in 1764, and the Americans had been given the year to suggest alternative methods of raising the money needed to administer and defend the colonies. Instead, this year was used to organise opposition to the act.The developmentIn the face of such a grave situation, colonial delegates代表from 12 colonies (Georgia didn’t send its delegates) met in Philadelphia on September 5, 1774,to consult upon the present unhappy state of the colonies. This meeting has been known as the First Continental Congress, which encouraged Americans to refuse to buy British goods. Colonial militia units were organized.The spark火花came in the Boston area on April 19, 1775. When American revolutionaries were removing munitions 军需品from the arsenals兵工厂in the small towns of Lexington and Concord, about 50 kilo meters from Boston. Some British troops, after a night of marching, reached the village of Lexington, they met about 50 minutemen民兵. There was a dense fog and shots soon broke out from both sides.

Before long, the American troops defeated the British at Saratoga in Northern New York. This was a great turning point of the war, leading directly to an alliance between the U.S and the France.In 1781, Washington, with the help of the French army, penned the British troops at York town. On Virginia coast and, on October 19, the same year, the British general Cornwallis surrendered.In September 1783, the Treaty of Paris was signed. The peace treaty British recognized the independence, freedom, and sovereignty of the 13 states. The large expansion of land to the west of the colonies, with the Mississippi as the western limit, was also given to the 13 states.The American War of Independence was of great historical importance and influence.
