Thomas Jefferson

Thomas Jefferson (April 13, 1743 – July 4, 1826) was an American statesman, planter, diplomat, lawyer, architect, philosopher, and Founding Father who served as the third president of the United States from 1801 to 1809. He was the primary author of the Declaration of Independence. Following the American Revolutionary War and before becoming president in 1801, Jefferson was the nation's first U.S. secretary of state under George Washington and then the nation's second vice president under John Adams. Jefferson was a leading proponent of democracy, republicanism, and natural rights, and he produced formative documents and decisions at the state, national, and international levels.

Jefferson was born into the Colony of Virginia's planter class, dependent on slave labor. During the American Revolution, Jefferson represented Virginia at the Second Continental Congress. He served as the second governor of revolutionary Virginia from 1779 to 1781. In 1785, Congress appointed Jefferson U.S. minister to France, where he served from 1785 to 1789. President Washington then appointed Jefferson the nation's first secretary of state, where he served from 1790 to 1793. During this time, in the early 1790s, Jefferson and political ally James Madison organized the Democratic-Republican Party to oppose the Federalist Party during the formation of the nation's First Party System. Jefferson and Federalist John Adams became both personal friends and political rivals. In the 1796 U.S. presidential election between the two, Jefferson came in second, which made him Adams' vice president under the electoral laws of the time. Four years later, in the 1800 presidential election, Jefferson again challenged Adams and won the presidency. In 1804, Jefferson was reelected overwhelmingly to a second term.

As president, Jefferson assertively defended the nation's shipping and trade interests against Barbary pirates and aggressive British trade policies, promoted a western expansionist policy with the Louisiana Purchase, which doubled the nation's geographic size, and was able to reduce military forces and expenditures following successful negotiations with France. In his second presidential term, Jefferson was beset by difficulties at home, including the trial of his former vice president Aaron Burr. In 1807, Jefferson implemented the Embargo Act to defend the nation's industries from British threats to U.S. shipping, limiting foreign trade and stimulating the birth of the American manufacturing industry.

Jefferson is ranked by both scholars and in public opinion among the upper tier of American presidents. Presidential scholars and historians praise Jefferson's public achievements, including his advocacy of religious freedom and tolerance, his peaceful acquisition of the Louisiana Territory from France, and his leadership in supporting the Lewis and Clark Expedition. They acknowledge the fact of his lifelong ownership of large numbers of slaves and give differing interpretations of his views on and relationship with slavery.
