What precedent did thomas jefferson set for the role of the president during his time in office?

Thomas Jefferson (April 13, [O.S. April 2] 1743 – July 4, 1826) was an American Founding Father who was the principal author of the Declaration of Independence and later served as the third President of the United States from 1801 to 1809. Previously, he had been elected the second Vice President of the United States, serving under John Adams from 1797 to 1801. He was a proponent of democracy, republicanism, and individual rights motivating American colonists to break from Great Britain and form a new nation; he produced formative documents and decisions at both the state and national level.

As President, Jefferson pursued the nation's shipping and trade interests against Barbary pirates and aggressive British trade policies. He also organized the Louisiana Purchase, almost doubling the country's territory. As a result of peace negotiations with France, his administration reduced military forces. He was reelected in 1804. Jefferson's second term was beset with difficulties at home, including the trial of former Vice President Aaron Burr. American foreign trade was diminished when Jefferson implemented the Embargo Act of 1807, responding to British threats to U.S. shipping. In 1803, Jefferson began a controversial process of Indian tribe removal to the newly organized Louisiana Territory, and he signed the Act Prohibiting Importation of Slaves in 1807.
