Fürstentum Tarent
Meanwhile, Charles's son Ladislaus returned to reconquer Naples. Despite his many years of service to Louis's family, Raimondo knew he was allied with the losing side, and switched allegiances once more on the promise that he would be given the Principality of Taranto, which happened in April 1399. However, by 1405, Ladislaus came into conflict with Pope Innocent VII, whom he had previously supported on the condition that the pope not challenge his claim to the throne. 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.
