Abraham Lincoln: The Crucible of Congress Abraham Lincoln served a single two-year term in the United States House of Representatives as a Congressman from Illinois, yet the experience was momentous. In Congress, he quickly achieved national prominence as an opponent of the extension of slavery and as a leader of the Whig party. The time he spent on Capitol Hill helped clarify his thinking on important issues of the day and prepared him for the Presidency. This in-depth look at Lincoln as Congressman was written by a former Congressman from Lincoln's district. Features many photos and illustrations. Hardcover; 270 pages.
