The "Declaration of Independence" was primarily authored by Thomas Jefferson. This pivotal document was adopted on July 4, 1776, and outlined the American colonies' reasons for seeking independence from British rule. Jefferson drew upon Enlightenment ideas about individual rights and government by consent to craft the declaration. The text eloquently states the philosophical foundations of the United States, emphasizing liberty and the pursuit of happiness. Jefferson's words have had a lasting impact on American identity and democratic ideals worldwide. Other members of the Continental Congress, including John Adams and Benjamin Franklin, contributed to the editing process, but Jefferson is most recognized for his role as the principal writer.
