Northern Democrats were a faction within the Democratic Party in the United States during the mid-19th century that opposed the secession of Southern states and advocated for a negotiated peace with the Confederacy. Their beliefs centered around maintaining the Union while also addressing issues such as slavery and civil liberties, often putting them at odds with more radical factions. This group played a crucial role in the political landscape leading up to and during the Civil War, especially during the Election of 1860.
