In 1754, the United States was not yet an independent country, as it would be more than 20 years before the Declaration of Independence. America's future first President, George Washington, was only 21 at the time.
In the French and Indian War, the British Army, along with American militia volunteers, fought against the French Army and their Native American allies for control of North America.
So at that time, the colonies still were loyal to, and fought for, King George III of England as part of the British Empire. While there were colonial legislatures and King-appointed governors of each of the thirteen colonies, there was no US President until after the Revolutionary War.
