Step-by-step explanation:
Thomas Jefferson was an accomplished man with diverse interests and talents spanning politics, architecture, agriculture, and philosophy. He was a critical figure in American history, known as the author of the Declaration of Independence and for his contributions as the third President of the United States, during which he oversaw the Louisiana Purchase and launched the Lewis and Clark Expedition. Jefferson was a Virginia planter and held positions including delegate to the House of Burgesses, U.S. Minister to France, the first Secretary of State under George Washington, and Vice-President under John Adams. His values emphasized limited government, individual liberty, agrarianism, and states' rights, which reflected in policies during his presidency.
As a planter, Jefferson's agrarian values were evident, believing that the success and security of the United States was best supported through a strong agricultural base and widespread land ownership, which he associated with good citizenship. His vision for America was an 'empire of liberty,' rooted in rural, land-owning white men or yeoman republican farmers, whom he saw as the backbone of the republic. Jefferson's ideas on the relationship between government and its citizens, focusing on minimal federal interference, laid the groundwork for the founding principles of states' rights and continued to influence American politics well beyond his lifetime.
