by Britain and France during the Napoleonic Wars, President Jefferson arranged passage of the Embargo Act of 1807. In support of Jefferson's policy, which limited trade with foreign powers, Clay introduced a resolution to require legislators to wear homespun suits rather than those made of imported British broadcloth. The vast majority of members of the state house voted for the measure, but Humphrey Marshall, an "aristocratic lawyer who possessed a sarcastic tongue," voted against it. In early 1809, Clay challenged Marshall to a duel, which took place on January 19. While many contemporary duels were called off or fought without the intention of killing one another, both Clay and Marshall fought the duel with the intent of killing their opponent. They each had three turns to shoot; both were hit by bullets, but both survived. Clay quickly recovered from his injury and received only a minor censure from the Kentucky legislature. In 1810, U.S. Senator Buckner Thruston resigned to accept appointment to a position as a federal judge, and Clay was selected by the legislature to fill Thruston's seat. Clay quickly emerged as a fierce critic of British attacks on American shipping, becoming part of an informal group of "war hawks" who favored expansionist policies. He also advocated the annexation of West Florida, which was controlled by Spain. On the insistence of the Kentucky legislature, Clay helped prevent the re-charter of the First Bank of the United States, arguing that it interfered with state banks and infringed on states' rights. After serving in the Senate for one year, Clay decided that he disliked the rules of the Senate and instead sought election to the United States House of Representatives. He won election unopposed in late 1810. Speaker of the House Election and leadership The 1810–11 elections produced many young, anti-British members of Congress who, like Clay, supported going to war with Great Britain. Buoyed by the support of fellow war hawks, Clay was elected Speaker of the House for the 12th Congress. At 34, he was the youngest person to become speaker, a distinction he held until the election of 30-year-old Robert M. T. Hunter in 1839. He was also the first of only two new members elected speaker to date, the other being William Pennington in 1860. Between 1810 and 1824, Clay was elected to seven terms in the House. His tenure was interrupted from 1814 to 1815 when
