AP Syllabus focus: ‘Political and religious disputes led to rivalries and conflict between states, shaping how empires gained and defended influence.’
Rivalries in the early modern era (c. 1450–1750) were rarely accidental: states competed over borders, resources, and prestige, while religious divisions sharpened identities and justified sustained warfare.
Core causes of rivalries and interstate conflict
Political and strategic competition
States pursued security and imperial influence in a world of shifting frontiers and competing claims.
Territorial disputes: contested borderlands, buffer zones, and strategic cities created recurring wars as states tried to push defensible frontiers outward.
Dynastic politics: succession crises and marriage alliances could trigger conflicts over “legitimate” rule and inheritance claims.
Geopolitical containment: states fought to prevent a rival from becoming a regional hegemon, producing long-term, cyclical competition rather than one decisive war.
Economic pressures and contested resources
Economic interests often underlay political goals, especially where land routes, ports, and productive regions mattered for state revenue.
