Gonzalo Fernandez de Cordoba vs Ivan III the Great

Cordoba's Spanish army defeated the French at Cerignola, Italy. Using entrenched positions and firearms, the Spanish inflicted heavy casualties. This was the first major battle won primarily by arquebus fire.

Cordoba launched a surprise night attack across the Garigliano River, routing the French army. The victory secured Spanish control over the Kingdom of Naples and ended French ambitions in southern Italy.

Cordoba organized Spanish infantry into tercios, combining pikemen and arquebusiers in a flexible formation. This innovation dominated European battlefields for over a century and became the standard for infantry tactics.

Ferdinand II of Aragon appointed Cordoba as Viceroy of Naples, the highest office in the newly conquered kingdom. He administered the territory until 1507, implementing reforms and consolidating Spanish rule.

Ivan III married Sophia (Zoe) Palaiologina, niece of the last Byzantine emperor. This marriage allowed Ivan to claim succession to the Byzantine Empire, adopt the double-headed eagle as a symbol, and promote Moscow as the Third Rome.

Ivan III conquered the Novgorod Republic after a series of campaigns. He abolished the veche (assembly) and removed the veche bell, incorporating Novgorod's vast territories into the Grand Principality of Moscow.

Ivan III faced the Mongol army of Khan Akhmat across the Ugra River. After weeks of stalemate, the Mongols withdrew without battle. This event ended 240 years of Mongol suzerainty over Russia.

Ivan III promulgated a new legal code, the Sudebnik, which standardized laws across the Russian lands. It restricted peasant mobility by limiting the time for transfer between landowners, a step toward serfdom.

Ivan III launched a war against Lithuania, capturing the cities of Bryansk, Dorogobuzh, and Putivl. The war ended with the Truce of 1503, which ceded significant territories to Moscow.
