Thomas Jefferson is widely recognized for his crucial role in writing the Declaration of Independence. Drafted in 1776, the document articulated the American colonies' intent to separate from British rule and outlined the philosophy of individual rights and self-governance. Jefferson's eloquent prose and Enlightenment ideas emphasized liberty, equality, and the pursuit of happiness, which have since become foundational principles of American democracy. His efforts in drafting the Declaration not only defined the values of the new nation but also inspired democratic movements worldwide. Jefferson later became the third President of the United States and is remembered as one of the Founding Fathers.
