What did George Washington do to make the world a better place?

The major accomplishments of George Washington were the preservation of the Continental Army during the Revolution, the defeat of General Cornwallis at Yorktown, and the creation of the first government of the United States of America. Together, his first two accomplishments allowed the United States to secure its independence from Great Britain while the third ensured that the United States had a stable political, economic, and diplomatic foundation that prevented it from collapsing during its early years.
