 Jefferson’s wife Martha died on September 6, 1782. Overwhelmingly distraught, he found some consolation in an invitation to function as Minister to France—he needed to be away from Monticello—which he did from 1784 to 1789. He ended the post at the bidding of George Washington, who asked him to be his Secretary of State—a post he held till 1793. Political disagreements between Jefferson and Alexander Hamilton on political issues resulted in formation of the Republican and Federalist parties—the former, championing small, unobtrusive government and strict constructionism; the latter, larger, strong government and a less strict interpretation of the Constitution. After a brief retirement, he was elected Vice-President of the United States for one term that ended in 1801, and then President of the United States, which lasted two terms. His presidency, which began triumphantly with his conciliatory First Inaugural Address, was highlighted by the Louisiana Purchase in 1803, which doubled the size of the country; the subsequent Lewis and Clark Expedition, which ended in 1806; and the failed Embargo Act of 1807, which aimed, among other things, to punish England during its war with France, by prohibiting exchange of goods. During his tenure as president, his daughter Maria died (1804).
