OAH Lectures by Aaron Sheehan-Dean

Most histories of the American Civil War describe it as a domestic event. Instead, this lecture situates the conflict in the context of the other civil and national wars that happened at nearly the same time. By comparing and contrasting the American experience with the Indian Rebellion of 1857, the Polish Insurrection of 1863, and the Taiping Rebellion, we see the Civil War in a new light. Rather than being a unique or exceptional American event, we can see what Confederates shared with other rebels around the globe. This new framing also helps us see the commonalities between the US and the British, Russian, and Chinese empires, all large and ambitious states willing to use violence to maintain their authority.

At least three-quarters of a million lives were lost during the American Civil War. Given its seemingly indiscriminate mass destruction, this conflict is often thought of as the first “total war.” In fact, this notoriously bloody war could have been much worse. Military forces on both sides sought to contain casualties inflicted on soldiers and civilians. In Congress, in church pews, and in letters home, Americans debated the conditions under which lethal violence was legitimate, and their arguments differentiated carefully among victims—women and men, black and white, enslaved and free. Sometimes, these well-meaning restraints led to more carnage by implicitly justifying the killing of people who were not protected by the laws of war. As the Civil War raged on, the Union’s confrontations with guerillas and the Confederacy’s confrontations with black soldiers forced a new reckoning with traditional categories of lawful combatants and raised legal disputes that still hang over military operations around the world today.
