The position of Speaker started to gain its partisan role and its power in legislative development under Henry Clay (1811--1814, 1815--1820, and 1823--1825). In contrast to many of his predecessors, Clay participated in several debates, and used his influence to procure the passage of measures he supported--for instance, the declaration of the War of 1812, and various laws relating to Clay's ''American System'' economic plan. Furthermore, when no candidate received an Electoral College majority in the 1824 presidential election causing the President to be elected by the House, Speaker Clay threw his support to John Quincy Adams instead of Andrew Jackson, thereby ensuring Adams' victory. Following Clay's retirement in 1825, the power of the speakership once again began to decline, despite speakership elections becoming increasingly bitter. As the Civil War approached, several sectional factions nominated their own candidates, often making it difficult for any candidate to attain a majority. In 1855 and again in 1859, for example, the contest for Speaker lasted for two months before the House achieved a result. During this time, Speakers tended to have very short tenures. For example, from 1839 to 1863 there were eleven Speakers, only one of whom served for more than one term. To date, James K. Polk is the only Speaker of the House later elected President of the United States.
