Antonio de Leyva, Duke of Terranova

Antonio de Leyva, Duke of Terranova, Prince of Ascoli, Count of Monza (1480–1536) was a Spanish general during the Italian Wars.

After the death of Fernando d'Ávalos, Marquis of Pescara, he held further commands in Italy during the War of the League of Cognac and finally died shortly after attempting an invasion of Provence.

Belonging to a family from Navarre, Antonio de Leyva made his military debut in the Alpujarras (1502) during the struggle against the revolting Mudéjares from Granada and later served in Italy under the Gran Capitán (1503–1504).

Later on, under the Marquis of Pescara, he fought near Milan and in the unlucky campaign of Provence in 1524, in which they succeeded in looting the countryside but were forced to withdraw without having managed to conquer Marseille.

Antonio de Leyva died of gout during the campaign of Provence in 1536 but was buried in Milan in the now-destroyed church of San Dionigi.
