Using a blend of global, intellectual and cultural history, this book explores the geopolitics of Juan Perón and their relationship to, and impact on, the international history of the mid-20th century. Beginning with Perón’s formative years, it analyzes the concepts that helped shape his anti-imperialist views and traces these ideas over decades from his time in the Argentine Army through his rise to power, downfall, and eventual death in 1974. Dissecting how notions of imperialism, nationalism and decolonization fueled his ideology and approach to foreign policy, Juan Perón’s Anti-Imperialist Geopolitics takes a long-term approach to understand his geopolitical evolution over time. While Peronism has continued to be an influential movement in Argentine politics and remains a lively research topic, Perón’s geopolitics have received scant attention despite their significance to his popularity and legacy. This book offers a corrective to this, situating Peronism, Argentina, and Latin America on the international stage during the 20th century. From his pioneering role in the era’s anti-imperialist solidarity movement, his expansion of the Peronist development model to a global model and his efforts to establish a post-imperial world through the Non-Aligned Movement, Juan Perón’s Anti-Imperialist Geopolitics argues that Perón merits recognition as a leading 20th-century geopolitical thinker.
