The Constitutional Union Party was a political party in the United States formed in 1860. It aimed to preserve the Union and avoid the growing tensions between the North and South over issues like slavery. The party attracted moderate politicians who sought a middle ground and emphasized adherence to the U.S. Constitution. In the 1860 presidential election, the Constitutional Union Party nominated John Bell as its candidate. Although the party did not win the election, it played a significant role in highlighting the divisions within the country during a critical period leading up to the American Civil War.
