Of all of the political figures with whom Abraham Lincoln interacted, few are as inextricably tied to his memory as Stephen Douglas. Born in Vermont, he moved to Illinois in 1833 to establish a legal practice. He was elected to the Illinois House of Representatives as a Democrat in 1836, where he first met Abraham Lincoln. Six years later, he was elected to the United States House of Representatives.

A close ally of presidents James K. Polk and Millard Fillmore, Douglas established himself early on as a reliable pro-slavery voice in Congress. He supported the annexation of Texas as well as the Mexican-American War and was one of four northern Democrats to vote against the Wilmot Proposal, which would have banned slavery in any territories ceded by Mexico at the war's end. He was elected to the United States Senate in 1847.

After winning the 1858 Republican nomination for the Senate from Illinois, Abraham Lincoln delivered his famous "House Divided" speech and prepared for a hard-fought campaign against Douglas, who continued to oppose any meddling whatsoever with the institution of slavery. Lincoln and his campaign team began following Douglas across the state, delivering campaign speeches immediately after him, until he finally agreed to a series of debates with Lincoln, which are now remembered as the Lincoln-Douglas Debates. Despite voter turnout exceeding that of the 1856 presidential election, Lincoln was defeated, and Douglas retained his seat. Two years later, they would face off again, this time for the presidency. Lincoln ultimately won, with Douglas carrying only Missouri, and every state won by John C. Breckinridge ultimately seceding from the Union only a few months later.

Despite his defeat, Douglas actively campaigned against secession, joining several committees that sought to prevent a break-up of the Union. During Lincoln's inaugural address on 4 March 1861, Douglas stood behind his former opponent with Lincoln's hat in hand, saying at the time that "If I can't be the President, at the least I can hold his hat." Two months later, Douglas contracted typhoid fever and ultimately died of it on 3 June, coincidentally the same day that the Battle of Philippi took place. Secretary of War Simon Cameron issued a circular to Union troops mourning his death, describing Douglas as "a great statesman...a man who nobly discarded party for his country."
