Who was the principal author of the Declaration of Independence?

The principal author of the Declaration of Independence was Thomas Jefferson. He was selected by the Continental Congress to draft the document due to his eloquent writing style and strong beliefs in individual rights and government accountability. Jefferson's drafting took place in June 1776, and the Declaration was officially adopted on July 4 of the same year.

His articulation of the colonies’ desire for independence from British rule and the philosophical underpinnings of rights, such as "life, liberty, and the pursuit of happiness," has had a lasting impact on American democracy and ideals. Jefferson's commitment to Enlightenment principles significantly shaped the content of the Declaration, which articulated the colonies' grievances against King George III and justified their break from British authority. This foundational text has influenced various democratic movements around the world, underscoring Jefferson's pivotal role in American history.
