Question: did thomas jefferson wrote the declaration of independence when he was president

Answer: No, Jefferson was the primary author of the Declaration of Independence. At age 33, he was one of the youngest delegates to the Second Continental Congress beginning in 1775 at the outbreak of the American Revolutionary War, where a formal declaration of independence from Britain was overwhelmingly favored. Jefferson chose his words for the Declaration in June 1775, shortly after the war had begun, where the idea of Independence from Britain had long since become popular among the colonies. He was inspired by the Enlightenment ideals of the sanctity of the individual, as well as by the writings of Locke and Montesquieu.
