Raimondo was born in
Taranto, the second son of
Nicola Orsini (1331–1399), 3rd Count of
Nola, grand Justiciar and also Grand Chancellor of the Kingdom of Naples, and his wife Giovanna of
Sabran. His paternal grandparents were Roberto Orsini di Nola (1295–1345), 2nd Count of Nola, Grand Justiciar of Naples, and the heiress Sveva Del Balzo (born in the first years of 14th century), Countess of Soleto, heiress of des Baux. Innocent excommunicated Ladislaus, but offered to pardon any of Louis II's supporters who came to his side, which Raimondo did, but he died soon afterwards on 17 January 1406, before Ladislaus had even learned of Raimondo's betrayal. Raimondo is buried at the church of Santa Caterina d'Alessandria in
Galatina, which he had commissioned, together with his son and heir
Giovanni Antonio. Despite having been one of the most important people in the history of southern Italy, there has been little scholarship done on Raimondo's life. One reason for this is that there are only six surviving documents from his years in the government of the Kingdom of Naples. This is likely due his being declared a nonperson by Ladislaus, resulting in the destruction of many sources that would give insight into his life. ==List of titles==
