Gary Gallagher: American Civil War, Slavery, Lincoln, Grant & Lee

Gallagher separates the cause of the Civil War from a simple story of an abolitionist North confronting a slaveholding South. The decisive political dispute in the 1840s and 1850s concerned whether slavery could expand into federal territories. Immediate abolitionists were a small minority among white Americans, even in the North. Republican opposition to expansion therefore did not amount to a national promise of immediate abolition. Yet slaveholders could see territorial restriction as a path toward permanent political minority and eventual threats to slavery where it already existed.

Lincoln’s election became threatening in that longer perspective. Gallagher connects Republican territorial policy with Lincoln’s and Seward’s earlier statements that a country divided between slavery and freedom could not endure indefinitely. Seven slaveholding states responded by seceding. He also stresses that opposition to slavery and opposition to racial prejudice were different positions: white Northerners could reject expansion because they wanted territories reserved for white economic opportunity while remaining deeply prejudiced against Black people.

The institution’s reach exceeded the minority of Southern households that owned enslaved people. Gallagher identifies labor control, racial social control, fear of emancipation, and everyday reciprocal arrangements between wealthier slaveholders and small farmers as connections sustaining white support. He rejects the claim that slavery was already dying economically. Its continued expansion into other forms of work makes the idea of painless, imminent disappearance an unsupported account within his interpretation.

The economic stakes were enormous in Gallagher’s account: the 1860 census valued enslaved property at roughly three billion dollars, above the combined value he gives for industry and railroads. Lex asks why abolition elsewhere did not require comparable mass death. Gallagher cautions that Britain emancipated people overseas, whereas American slaveholders feared the consequences of formerly enslaved people living among them. This comparison explains part of the resistance; it does not turn the war’s original purpose into abolition.

The federal war aim began as suppressing rebellion. By 1862, striking slavery became a means of undermining the labor system that allowed the Confederacy to mobilize an exceptionally high share of white military-age men. Lincoln grounded the Emancipation Proclamation in wartime authority, both because presidential authority was limited and because he needed Democratic support for the war. Its territorial exemptions followed that legal argument: military advance would give practical effect to emancipation in the areas it covered.

Gallagher distinguishes slavery as the cause of war from Union as the motivation of most white federal volunteers. To those men, the republic offered a political voice and the possibility of economic advancement, even though its franchise excluded many people by modern standards. He also resists a purely North-versus-South map: four slaveholding states remained in the United States. Calling the opponents two republics describes their institutions and rival claims to revolutionary inheritance; it does not imply approval of the Confederacy.
