King George III was the British monarch at the time of the Revolutionary War. Interestingly, rather than seeing him as their ultimate enemy, many delegates to the First Continental Congress hoped that George III would be their defender, even reaching out to him in what is now known as the Olive Branch Petition. King George’s refusal to help the colonists was ultimately the final straw, prompting Thomas Jefferson to formalize America’s break from its mother country via the Declaration of Independence.
