Latin America’s historical narrative is intricately woven with the complex interrelationship between armed forces and politics. From the authoritative reign of 19th-century figures like Juan Manuel de Rosas to the military’s political prominence in the 20th century, the region’s trajectory has been profoundly shaped by this alliance. The shift towards democracy during the 1980s curtailed direct military influence, although discussions on their role endure. Present-day challenges, exemplified by the rise of organized crime, have propelled armed forces into new roles. Peru and Mexico serve as pertinent examples, where armed actors with economic and military clout challenge state authority. Governments are now recalibrating the role of armed forces to strike a harmonious balance between security imperatives and democratic governance. This article delves into these nuances, spotlighting Peru and Mexico as illustrative case studies within this intricate framework.
