Historians mark the Battle of Rocroi in 1643 as a decisive turning point. The French victory, with 4,000 casualties compared to the Spanish losses of 7,000 dead and wounded, plus 8,000 captured, marked the first defeat of the Spanish Tercios in nearly a century. Supported by the French, revolts by the Catalonians, Neapolitans, and Portuguese further weakened Spanish control. This battle is often considered the end of Spanish dominance in Europe. Notably it was also the beginning of French hegemony in the region.
