American History AIR Practice Test – Free Practice Exam & Study Guide

The Declaration of Independence was primarily authored by Thomas Jefferson, who served as the main drafter of this pivotal document in American history. Jefferson was chosen for this task because of his eloquent writing style and strong beliefs in individual rights and liberty. The Declaration, adopted on July 4, 1776, articulates the colonies' reasons for breaking away from British rule, emphasizing principles such as the notion that all men are created equal and have the right to life, liberty, and the pursuit of happiness.

While other prominent figures, such as John Adams and Benjamin Franklin, played significant roles in the American Revolution and supported Jefferson during the drafting process, they were not the primary author of the document. George Washington, though a crucial leader during the conflict, was not involved in the writing of the Declaration itself. Understanding Jefferson's contributions provides insight into the philosophical foundations of the United States and the values that guided the nation's formation.
