In 1810 Clay was elected to the U.S. House of Representatives and served (1811–14) as speaker. As spokesman of Western expansionist interests and leader of the "war hawks," Clay stirred up enthusiasm for war with Great Britain and helped bring on the War of 1812. He resigned (1814) from Congress to aid in the peace negotiations leading to the Treaty of Ghent.
He again served (1815–21) in the House, again was speaker (1815–20), and began to formulate his "American system," a national program that ultimately included federal aid for internal improvements and tariff protection of American industries. In 1821, Clay, to pacify sectional interests, pushed the Missouri Compromise through the House. In the House for the last time (1823–25), he once more became (1823) speaker, and he did much to augment the powers of that office. In this session he secured the western extension of the National Road and, against much opposition, eloquently carried through the Tariff of 1824.
