The Battle of Seminara was a significant military encounter between a French army, led by Louis d'Armagnac, and a significantly larger coalition force of Neapolitan and Spanish troops. The conflict took place in June 1495, during the Italian Wars, which were characterized by a complex interplay of territorial claims and the involvement of multiple European powers vying for control in Italy. The French, although numerically inferior, employed effective strategies, including the use of artillery and cavalry to flank the enemy, which led to a resounding victory against their foes. This battle was a precarious fight for dominance and further exemplified the shifting military tactics of the period, particularly against a backdrop of evolving warfare strategies in Renaissance Italy.

In the aftermath of the battle, Gonzalo de Córdoba, a prominent Spanish military leader, analyzed the outcomes and tactics employed by both sides. Recognizing the need for improved organization and maneuverability in his own ranks, he conceptualized the Tercios. This formation emphasized a combination of infantry, cavalry, and artillery, allowing for enhanced coordination on the battlefield. The Tercios would become instrumental in Spanish military strategy for centuries, confirming the effectiveness of integrated and disciplined troops, setting a new standard for armies across Europe. The Battle of Seminara, therefore, did not only signify a tactical defeat for the Spanish and Neapolitans but also served as a catalyst for profound changes in military organization and training.
