Jacopo Caldora, also known as Giacomo Caldora, was an Italian nobleman, military leader, and captain of fortune who lived from 1369 to 1439. His legacy is closely tied to the history of Vasto, where he became lord in 1422.

The son of Giovanni Antonio Caldora, Jacopo displayed exceptional military talent from a young age, quickly rising through the ranks of the Neapolitan army. He gained the trust of prominent figures of the time, including Queen Joanna II of Anjou, who appointed him Grand Constable of the Kingdom and granted him the title of Duke of Bari.

In 1424, during the War of L’Aquila, Jacopo Caldora achieved a decisive victory over the renowned leader Braccio da Montone at the Battle of Sant’Angelo. This triumph marked a turning point in the struggle for control of the Kingdom of Naples and cemented Caldora’s reputation as one of the most skilled commanders of his era.

In 1422, Jacopo Caldora acquired the title of Lord of Vasto, the ancestral home of his family, and chose to make the city his winter residence.

During his rule, Vasto flourished, experiencing significant prosperity and development. He oversaw the construction of new fortifications, including the Caldoresco Castle, which remains a symbol of the city today. Additionally, he initiated the building of a grand palace that would later be inherited by the d’Avalos family and named Palazzo d’Avalos in their honor.

Jacopo Caldora died in 1439 during the siege of Colle Sannita, leaving his children a vast domain that included Vasto and numerous other cities. His legacy as a brilliant military strategist and wise ruler has earned him a place among the most influential figures of the 15th century.
