In U.S. politics, the Great Triumvirate refers to a triumvirate of three statesmen who dominated American politics for much of the first half of the 19th century, namely Henry Clay of Kentucky, Daniel Webster of Massachusetts and John C. Calhoun of South Carolina. These men's interactions in large part tell the story of politics under the Second Party System. All three were extremely active in politics, served at various times as Secretary of State and served together in both the House of Representatives and the Senate. Clay, the oldest, emerged on the national political scene first, serving as counsel for Aaron Burr in his treason trial and serving two short stints in the Senate before being elected Speaker of the House of Representatives for the Twelfth Congress. Calhoun was a freshman member of this Congress and his friendship and ideological closeness with Clay helped propel him to prominence as a leader of the war hawk faction agitating for a war which would eventually be declared as the War of 1812. Webster was elected in 1813 to Congress and immediately became a leading anti-war and anti-administration Federalist. Webster wrangled with the nationalists Clay and Calhoun on post-war issues such as the chartering of the Second Bank of the United States and the Tariff of 1816. After the Fourteenth Congress, Calhoun became Secretary of War and Webster declined reelection to focus on his law practice in Boston, a practice which took him before the Supreme Court in landmark cases like Dartmouth College v. Woodward, Gibbons v. Ogden and McCullouch v. Maryland in which he represented the Bank of the United States. The three were reunited in the Senate in 1832, with Calhoun's resignation from the vice presidency and election to the Senate in the midst of the Nullification Crisis. The three would remain in the Senate until their deaths, with exceptions for Webster and Calhoun's tenures as Secretary of State and Clay's presidential campaigns in 1844 and 1848. The time these three men spent in the Senate represents a time of rising political pressure in the United States, especially on the matter of slavery. With each one representing the three major sections of the United States at that time and their respective mindsets, the Great Triumvirate was responsible for symbolizing the opposing viewpoints of the American people and giving them a voice in the government. The debates leading to the Compromise of 1850 were the last great hurrah for the triad as they saw at the same time the emergence of a new generation of political leaders like Jefferson Davis, William H. Seward and Stephen A. Douglas. Calhoun was so ill at the time of the Senate debate on the Compromise that he was unable to deliver his fiery speech opposing it, instead having it read for him by James Mason while he sat in the chamber. Calhoun would die just two weeks later on March 31, 1850. Within three years, Clay and Webster would die as well, passing the torch to the next generation of political leadership.
