In 1834, Lincoln was elected to the state legislature, in which he served four successive terms (until 1841) and achieved prominence as a Whig. In 1836 he obtained his license as an attorney, and the next year he moved to Springfield, where he became a law partner of John T. Stuart. Lincoln's practice steadily increased. That first partnership was succeeded by others, with Stephen T. Logan and then with William H. Herndon, who was later to be Lincoln's biographer. Lincoln displayed great ability in law, a ready grasp of argument, and sincerity, color, and lucidity of speech.
In 1842 he married Mary Todd (see Lincoln, Mary Todd) after a troubled courtship. He continued his interest in politics and entered on the national scene by serving one term in Congress (1847–49). He remained obscure, however, and his attacks as a Whig on the motives behind the Mexican War (though he voted for war supplies) seemed unpatriotic to his constituents, so he lost popularity at home. Lincoln worked hard for the election of the Whig candidate, Zachary Taylor, in 1848, but when he was not rewarded with the office he desired—Commissioner of the General Land Office—he decided to retire from politics and return to the practice of law.
