Stephen Arnold Douglas, an American politician, attorney, and judge, was one of the most prominent figures during the 19th century. Known for his debates with Abraham Lincoln, he was often referred to as "The Little Giant" due to his diminutive stature and fiery personality. Other synonyms for Douglas include "The Illinois Giant", "The Rail Splitter's Rival", and "The Compromise Candidate". Despite his unsuccessful bid for presidency in 1860, he remains a significant figure in American political history, remembered for his advocacy of popular sovereignty and the Union cause during the Civil War.
