Who was the ruler of America during the declaration of independence?

During the Declaration of Independence in 1776, America was not ruled by a single leader but was under British colonial rule, with King George III as the monarch of Great Britain. The Declaration, adopted on July 4, 1776, was a statement of the American colonies' intention to break free from British authority and establish their own sovereignty. The Continental Congress, representing the colonies, played a crucial role in drafting and adopting the document.
