Geopolitica d'età moderna. Linee globali, territorialità politica e incertezza geografica

Geopolitics of Early Modern Age. Global Lines, Territorial Power, and Geographical Uncertainty. – This article explores the origins of geopolitics in the early modern period (16th-17th centuries), demonstrating how three key elements – the establishment of global lines, the relationship between state power and territoriality, and geographical uncertainty – shaped both the politics of the era and contemporary geopolitical thought. Through the analysis of cartographic sources (e.g., the Cantino Planisphere, 1502), treaties (Tordesillas, Cateau-Cambrésis), and theoretical works (Schmitt, Bo-tero, Machiavelli), it argues that: global lines codified the division of the world into spheres of influence, foreshadowing bipolar or multipolar logics; political territoriality emerged forcefully, crystallizing in national borders and the principle of sovereignty (Westphalia), despite simultaneous global expansion; geographical uncertainty, stemming from discrepancies between maps and reality, became a defining feature of geopolitics, with echoes in today’s crisis of international orders. The article thus reinterprets the roots of geopolitics, locating them not in the 19th century but in the crucible of early modernity, with implications for understanding contemporary power dynamics
