Stephen A. Douglas, American lawyer and politician, 7th Secretary of State of Illinois (born 1813)

Stephen Arnold Douglas was an American politician and lawyer from Illinois. A Democrat, he served in the United States Senate for fourteen years and defeated Abraham Lincoln to win reelection in 1858, a campaign known for the pivotal Lincoln–Douglas debates. He was the representative of the Northern Democrats in the 1860 United States presidential election; with the Democrats split between northern and southern factions in the leadup to the American Civil War, he was defeated by Lincoln, the Republican nominee. During his senate career, Douglas was one of the brokers of the Compromise of 1850, which sought to avert a sectional crisis over the issue of slavery. To deal with the volatile issue of whether to extend slavery into US territories, Douglas became the foremost advocate of popular sovereignty, which held that the voters of each territory should be allowed to decide. At just 5 feet 4 inches (1.63 m) tall, Douglas was nicknamed the "Little Giant" because he was short in physical stature but a forceful and dominant figure in politics.
