Gonzalo Fernández de Córdoba

Gonzalo Fernández de Córdoba (1 September 1453 – 2 December 1515) was a Spanish general and statesman. He led military campaigns during the Conquest of Granada and the Italian Wars, after which he served as Viceroy of Naples. For his extensive political and military success, he was made Duke of Santángelo (1497), Terranova (1502), Andría, Montalto and Sessa (1507), and earned the nickname El Gran Capitán ("The Great Captain").

Held as one of the greatest generals in history, he became the first European to decisively employ firearms on the battlefield, and among the first to reorganize infantry with pikes and firearms. His extensive combined arms doctrine, which led to the formation of the tercios after his death, were instrumental in making the Spanish army the dominant land force in Europe for over a century and a half. He has been credited with marking the transition between medieval and modern warfare, leaving a lasting influence in military thinking up to the 20th century.
