Input: Consider Input: Question: Who was the pope before Bruno of Toul? Passage:According to some chroniclers, Hildebrand moved to Cluny after Gregory VI's death, which occurred in 1048; his declaration to have become a monk at Cluny must not be taken literally. He then accompanied Abbot Bruno of Toul to Rome; there, Bruno was elected pope, choosing the name Leo IX, and named Hildebrand as deacon and papal administrator. Leo sent Hildebrand as his legate to Tours in France in the wake of the controversy created by Berengar of Tours. At Leo's death, the new Pope, Victor II, confirmed him as legate, while Victor's successor Stephen IX sent him and Anselm of Lucca to Germany to obtain recognition from the Empress Agnes de Poitou. Stephen died before being able to return to Rome, but Hildebrand was successful; he was then instrumental in overcoming the crisis caused by the Roman aristocracy's election of an antipope, Benedict X, who, thanks also to Agnes's support, was replaced by the Bishop of Florence, Nicholas II. With the help of 300 Norman knights sent by Richard of Aversa, Hildebrand personally led the conquest of the castle of Galeria Antica where Benedict had taken refuge. Between 1058 and 1059, he was made archdeacon of the Roman church, becoming the most important figure in the papal administration.


Output: He then accompanied Abbot Bruno of Toul to Rome; there, Bruno was elected pope, choosing the name Leo IX, and named Hildebrand as deacon and papal administrator
