After Barbary explores the connection between the United States and North Africa between the Barbary Wars of the early nineteenth century and the era of European decolonization after World War II. Timothy Mason Roberts offers a new approach to the study of empires, highlighting the significance of Algeria in French-American relations from France's first occupation of the country through the first years of independence of the Republic of Algeria. As Roberts demonstrates, imperial authorities in Washington, DC, Paris, and Algiers rarely intentionally collaborated in institutional partnerships or alliances. Rather, American, French, and Algerian politicians, soldiers, writers, and revolutionaries, often acting at cross purposes and across political and cultural boundaries, sought power by imagining and constructing Algeria as a fissured, dynamic, trans imperial space. Focusing on issues of settler colonialism, irregular warfare, racialized citizenship, territorial incorporation, and pan-African identity, After Barbary shows how French Algeria helped make the American and French empires.
