Who was the third President of the United States?

Thomas Jefferson served as the third President of the United States from 1801 to 1809. His presidency is significant not only for the policies he implemented but also for how he shaped the evolving role of the presidency itself. Jefferson was the principal author of the Declaration of Independence and played a crucial role in promoting the idea of a democratic government based on the will of the people. During his time in office, he oversaw the Louisiana Purchase in 1803, which doubled the size of the United States and greatly expanded its territorial integrity. Jefferson’s commitment to individual rights and limited federal government principles laid foundational ideals that continue to influence American democracy today.
