George Washington was a key factor in the success of the American Revolution due to his leadership. He was a wealthy farmer who had many slaves working for him in Virginia.
Washington served in the British army in the war against the French. After 1765, he opposed British policies on taxing the Americans and he attended the First Continental Congress in 1774. In 1775, the Second Continental Congress which met in Philadelphia made Washington the commander-in-chief of the American army.
In 1775, the British tried to end the siege in Boston at the Battle of Bunker Hill, but they failed. When Washington arrived in Boston after the battle, he brought order and discipline to the American Army. They began to bombard the city with cannons. In 1776, Washington had won his first battle.
At first, Americans just wanted the British to stop taxing them but most Americans like Washington wanted independence. Therefore, Thomas Jefferson wrote the Declaration of Independence and was passed by Congress on the 4th of July 1776. Washington was involved in many more battles which he suffered defeats in 1776 at Long Island.
On Christmas Day 1776, Washington and his troops crossed the Delaware River and attacked British troops in Trenton, New Jersey. This caught British off guard and was a victory for Washington.
Later on, Washington had captured the American capital of Philadelphia and spent the winter in Valley Forge. They had also won an important battle in Saratoga. Washington and other members of Congress urged the King of France to attack British colonies which would mean British troops were also fighting the French. Many men died at Valley Forge due to disease, frostbite and shortage of food. Soldiers from Europe helped train American troops such as Baron Friedrich von Steuben.
The Battle of Yorktown was when the British sent troops to the south led by General Cornwallis and they captured the city of Charlestown in 1780 and captured 5,000 American soldiers.
A further few battles, Cornwallis was trapped by Washington at Yorktown, Cornwallis surrendered in 1781, the war was over and won.
After the Treaty of Paris was passed and America was now independent and passed its US Constitution. Washington became the first president in 1789 and served two terms and later retired to his farm and died in 1799.
