The statement is historically sound. By 1500, Western Europe had rebounded from the Black Death (1347–1351, 30–50% mortality) and entered a long economic upswing that foreshadowed early modernity.
Pre-plague (1300): ~75–80M. Post-plague nadir (1400): ~50–55M. 1500: ~65–70M — nearing pre-crisis levels. Drivers: reduced plague recurrence (quarantine, immunity), agricultural gains (three-field → convertible husbandry, new crops), peasant bargaining power (labor scarcity → higher wages, commutation of labor services to rent), urban recovery.
Feudalism → early capitalism. Merchant class ascendant. State centralization (France, England, Spain). Renaissance humanism reshaping knowledge. The Great Divergence roots lie here.
1500 wasn't a peak—it was a launchpad.
