Lecture
The Great Horse Flu: A Forgotten Contagion and the Face of Reconstruction America
Imagine a world without cars, trucks, trains, or tractors—a world in which nearly everything depended on horses, donkeys, and mules. Then, in the fall of 1872, those animals began falling mysteriously ill.
Over the next fifteen months, a remarkably contagious strain of influenza sickened as many as 90% of the equines across Canada, the United States, and parts of Cuba, Mexico, and Central America. The consequences were staggering.
Drawing on his 2026 book, The Great Horse Flu of 1872, Thomas Andrews will take us back to a moment when an animal epidemic brought transportation and commerce to a standstill, disrupted daily life, intensified social conflict, and even threatened the fragile progress of Reconstruction after the Civil War.
Andrews will explore the outbreak’s devastating effects and reveal how the Great Horse Flu paralyzed the American economy, intensified social conflict, and undermined the viability of Radical Reconstruction. This fascinating and largely forgotten episode offers a striking reminder of just how profoundly an epidemic can reshape a society – and how dependent nineteenth-century America was on the animals that powered it.
