British general Burgoyne's surrender at Saratoga in the American Revolution
Defending the Colonies against attack by the French and others had cost the British a great deal of money. As a result, the British had very high taxes in their country. They thus decided to shift some of their financial burden to the colonists. The Stamp Act of 1765, which taxed all legal documents, newspapers and other documents, was met with a great uproar in the Colonies. In 1766, this tax was repealed, but it was just the beginning of the problems between the colonists and the British. The Boston Tea Party in 1773 was an act of revolt against the British and their tax on tea in the Colonies.
Tensions such as these eventually led to the writing of the Declaration of Independence in 1776. A year earlier, the War of Independence, also known as the American Revolution, began. When the British finally surrendered on October 19, 1781, Americans were officially independent of Britain and set about establishing their own government.
