From 1845 to 1865 the Gulf of Mexico was at the center of American expansion and southern imperialism. A Continuous State of War: Empire Building and Race Making in the Civil War–Era Gulf South (University of Georgia Press, 2024) by Dr. Maria Angela Diaz tells the story of several communities, such as Galveston, New Orleans, and Pensacola, as well as countries such as Mexico and Cuba, to uncover the way that wars within the upper rim of the Gulf of Mexico facilitated American and southern attempts to conquer Latin American nations. In the push for westward expansion that preceded the Civil War, white southerners along with other Americans engaged in violent conquest in Latin America and the American West. Through the wars that are chronicled here, white southern concepts of race became more rigidly fixed.

Dr. Maria Angela Diaz covers several conflicts leading up to the Civil War with Mexicans, Cubans, and Native Americans. She places the Civil War within this framework and follows the trajectory of relations with Latin America through the end of the Civil War and ex-Confederates’ attempts to emigrate abroad. Gulf Coast communities facilitated both the physical efforts to seize territory and the construction of the highly racialized imperialist ideas that reimagined Latin America as a region that could secure the South’s future. Yet the pursuit of that territory created a fluctuating and uncertain situation that shaped the choices of the diverse peoples who lived along the upper rim of the Gulf of Mexico in ways they did not expect.

This interview was conducted by Dr. Miranda Melcher whose new book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.
