One This Day in History: July 4, 1826
After July 4, 1776, Adams traveled to France as a diplomat, where he proved instrumental in winning French support for the Patriot cause, and Jefferson returned to Virginia, where he served as state governor during the dark days of the American Revolution. After the British defeat at the Battle of Yorktown in 1781, Adams was one of the negotiators of the Treaty of Paris that ended the war, and with Jefferson he returned to Europe to try to negotiate a U.S.-British trade treaty.
After the ratification of the U.S. Constitution, Adams was elected vice president to George Washington, and Jefferson was appointed secretary of state. During Washington's administration, Jefferson, with his democratic ideals and concept of states' rights, often came into conflict with Secretary of the Treasury Alexander Hamilton, who supported a strong federal government and conservative property rights. Adams often arbitrated between Hamilton and his old friend Jefferson, though in politics he was generally allied with Hamilton.
In 1796, Adams defeated Jefferson in the presidential election, but the latter became vice president, because at that time the office was still filled by the candidate who finished second. As president, Adams' main concern was America's deteriorating relationship with France, and war was only averted because of his considerable diplomatic talents. In 1800, Jefferson's Democratic-Republicans (the forerunner of the Democratic Party) defeated the Federalist party of Adams and Hamilton, and Adams retired to his estate in Quincy, Massachusetts.
As president, Jefferson reduced the power and expenditures of the central government but advocated the purchase of the Louisiana Territory from France, which more than doubled the size of the United States. During his second administration, Jefferson faced renewed conflict with Great Britain, but he left office before the War of 1812 began. Jefferson retired to his estate in Monticello, Virginia, but he often advised his presidential successors and helped establish the University of Virginia. Jefferson also corresponded with John Adams to discuss politics, and these famous letters are regarded as masterpieces of the American enlightenment.
