Example Input: Question: How long had Prüm Abbey existed when Eygilo left to become the abbot of Flavigny? Passage:The fame of Flavigny was due partly to the relics which it preserved, and partly to the piety of its monks. The monastery was at the height of its reputation in the eighth century, in the time of the Abbot Manasses, who was appointed by Pippin the Short. In 760/62, Manasses attended the council of Attigny. Pippin's successor, Charlemagne, authorized Manasses to found the Carolingian style monastery of Corbigny. The same Manasses transferred from Volvic to Flavigny the relics of Saint Praejectus. Abbot Apollinaris, appointed by Charlemagne in 802, was also abbot of Saint-Bénigne de Dijon and Môutier-Saint-Jean. Charlemagne's son, Louis the Pious, used Abbot Adrevaldus as an envoy to Septimania in 834 and 838, according to the Historia Hludowici imperatoris. However, these dates do not correspond to those given in the abbey's only list, which says that Adrevaldus became abbot in 839 and ruled for three years. Eygilo, the founder of Prüm Abbey, left his own establishment to become abbot of Flavigny in 860. He set up monks at Corbigny, but later left Flavigny when he was appointed Archbishop of Sens. His successor, Geylo, resigned to become abbot of Tournus and was later appointed bishop of Langres.

Passage:This is a list of campaigns personally led by Mehmed II or Sultan Mehmed the Conqueror (30 March 1432 – 3 May 1481) (Ottoman Turkish: محمد ثانى, Meḥmed-i s̠ānī; Turkish: II. Mehmet; also known as el-Fātiḥ, الفاتح, "the Conqueror" in Ottoman Turkish; in modern Turkish, Fatih Sultan Mehmet; also called Mahomet II in early modern Europe) was Sultan of the Ottoman Empire twice, first for a short time from 1444 to September 1446, and later from February 1451 to 1481. At the age of 21, he conquered Constantinople and brought an end to the Byzantine Empire, transforming the Ottoman state into an empire. Mehmed continued his conquests in Asia, with the Anatolian reunification, and in Europe, as far as Bosnia and Croatia. Mehmed II is regarded as a national hero in Turkey, and Istanbul's Fatih Sultan Mehmet Bridge is named after him.
