The correct chronological order is: 3. French and Indian War -> Passage of Stamp Act -> Battle of Saratoga -> Inauguration of George Washington.
The French and Indian war created a demand on the part of the British to raise taxes upon the colonists to pay off war debts. That led to the Stamp Act, which (along with other taxes) angered colonists to the point of revolution. A significant battle in the Revolution was the Battle of Saratoga. Following this battle and the end of the war, the United States were independent and George Washington was inaugurated as president.
