Thomas Jefferson was president for eight years, he was republican. he was part of the John Marshall court decision-Marbury vs. Madison of 1803, the Louisiana purchase of 1803, and the embargo act of 1807.
In November 1800, President John Adams, a Federalist, lost his bid for reelection to Thomas Jefferson, a Republican. The Federalists also lost control of Congress in the election. For the few months before the new President and Congress took office, however, Adams and his Federalist Party still had control. During these months, Adams persuaded Congress to pass a new law, the Judiciary Act of 1801. This act gave Adams the power to appoint several new federal judges. The Federalists hoped to fill the nation's courts with people who would be opposed to the policies of the incoming Republican administration. Adams was generally successful in this effort, appointing some 39 new judges. Adams's Secretary of State was to deliver the commissions, or official documents authorizing the appointments. The Secretary of State, though, failed to deliver the commissions to three new justices of the peace before Adams's term of office ended. One of the commissions was to go to William Marbury. When Thomas Jefferson became President in March 1801, he learned of Adams's attempt to pack the court with Federalist judges. He also discovered the failure to deliver the remaining commissions. To prevent these Federalists from becoming justices of the peace, Jefferson instructed his Secretary of State, James Madison, to refuse the appointments. Marbury went to the Supreme Court in an attempt to gain his post. He wanted the Court to issue an order forcing Madison to give Marbury his commission. The Judiciary Act of 1789 had given the Supreme Court the power to issue such an order.
The Louisiana Purchase of 1803 was a land deal between the United States and France, in which the U.S. acquired approximately 827,000 square miles of land west of the Mississippi River for $15 million.Nov 4, 2010
