How a series of medieval battles permanently shifted the balance of European military power
The Burgundian Wars between 1474 and 1477 saw the collapse of a rising superpower. When the Duke of Burgundy, Charles the Bold, faced the Old Swiss Confederacy, he encountered a new infantry tactic that rendered his traditional cavalry obsolete, forever changing the way wars were fought across the continent.
For roughly a century, the Valois dukes of Burgundy had consolidated a powerful state between France and the Holy Roman Empire. By controlling wealthy regions like Flanders and Brabant, they built an economic powerhouse capable of funding aggressive expansion. However, Charles the Bold’s ambition to unite his northern and southern territories brought him into direct conflict with the Swiss Confederacy, which was seeking independence from Habsburg influence.
The conflict escalated after Duke Sigismund of Habsburg pawned his Alsatian lands to Charles, leading to a series of diplomatic failures and border skirmishes. The Swiss, supported by an anti-Burgundian coalition that eventually included King Louis XI of France, utilized a formation known as the Gewalthaufen. This infantry tactic, which employed long spears to neutralize mounted cavalry, proved devastatingly effective. Charles suffered three major battlefield defeats, culminating in his death at the Battle of Nancy in 1477.
The aftermath of the war reshaped the map of Western Europe. With the Valois line extinguished, the Duchy of Burgundy collapsed, its lands divided between the French crown and the House of Habsburg through the marriage of Mary of Burgundy to Maximilian I. Beyond the territorial shifts, the war cemented the reputation of Swiss soldiers, launching an era where Swiss mercenaries became the most sought-after infantry in Europe. The conflict also forced internal adjustments within the Swiss Confederacy, eventually leading to the Stanser Verkommnis of 1481 to resolve disputes over war spoils.
Contemporary observers summarized Charles’s catastrophic decline by noting that he surrendered his wealth at Grandson, his martial reputation at Morat, and ultimately his life at Nancy. The war remains a pivotal moment in military history, marking the transition from cavalry-dominated warfare to the supremacy of disciplined infantry formations that would define the following centuries.
