Pope Innocent X
The Wars of Castro ended (while Taddeo Barberini held both titles) and members of the Barberini family (including Taddeo) fled into exile after the newly elected Pope Innocent X launched an investigation into members of the Barberini family. Later the Barberini reconciled with the papacy when Pope Innocent X elevated Taddeo's son, Carlo Barberini to the cardinalate and his brother Maffeo Barberini married a niece of the Pope and reclaimed the title, Prince of Palestrina.
