When the rule of law erodes, power shifts into darker hands. Shadows of Sovereignty examines the rise of cartel states-territories where criminal organizations evolve into governing forces, challenging the very idea of nationhood. Through the study of Mexico and beyond, it traces how violence, corruption, and survival converge to form alternate systems of order. Rooted in history and political reality, the book explores the blurred lines between government and crime, revealing a world where control is negotiated, not declared.
