Question: Who was the last leader of the the country that was established after the year-long siege in 831? Passage:At the time of his accession, Theophilos was obliged to wage wars against the Arabs on two fronts. Sicily was once again invaded by the Arabs, who took Palermo after a year-long siege in 831, established the Emirate of Sicily, and gradually continued to expand across the island. The defence after the invasion of Anatolia by the Abbasid Caliph Al-Ma'mun in 830 was led by the Emperor himself, but the Byzantines were defeated and lost several fortresses. In 831 Theophilos retaliated by leading a large army into Cilicia and capturing Tarsus. The Emperor returned to Constantinople in triumph, but in the autumn he was defeated in Cappadocia. Another defeat in the same province in 833 forced Theophilos to sue for peace (Theophilos offered 100,000 gold dinars and the return of 7,000 prisoners), which he obtained the next year, after the death of Al-Ma'mun.

Question: How many years were there between the death of Charlemagne and the first award of the Charlemagne Prize? Passage:The Charlemagne Prize (; full name originally Internationaler Karlspreis der Stadt Aachen, International Charlemagne Prize of the City of Aachen, since 1988 Internationaler Karlspreis zu Aachen, International Charlemagne Prize of Aachen) is a prize awarded for work done in the service of European unification. It has been awarded annually since 1950 by the German city of Aachen. It commemorates Charlemagne, ruler of the Frankish Empire and founder of what became the Holy Roman Empire, who resided and is buried in Aachen. Traditionally the award is given to the recipient on Ascension Day in a ceremony in the town hall of Aachen. In April 2008, the organisers of the Charlemagne Prize and the European Parliament jointly created a new European Charlemagne Youth Prize, which recognises contributions by young people towards the process of European integration. Patrons of the foundation are King Philippe of Belgium, King Felipe VI of Spain, and Henri, the Grand Duke of Luxembourg.

Nutt, facing his old team, came out victorious, 23–21. The Rebels followed that with a 17–7 home win against Auburn. On November 15, Ole Miss beat ULM, 59–0, to push their record to 6–4 and become bowl eligible for the first time since 2003. Ole Miss next beat No. 8 LSU, 31–13, in Baton Rouge, snapping a six-game losing streak to the Tigers, earning the Rebels an Associated Press ranking of No. 25, the first time in four years Ole Miss had been ranked, and putting them in position for a possible bid to the Cotton Bowl Classic in Dallas, Texas. The Rebels went on to beat SEC West and in-state rival Mississippi State, 45–0, in the Egg Bowl to finish the regular season at 8–4. The win over the Bulldogs moved the Rebels up to No. 22 in the AP Poll and landed the team their first ranking of the year in the Coaches' Poll, coming in at No. 25. Ole Miss defeated the No. 7 Texas Tech Red Raiders, 47–34, in the Cotton Bowl Classic.
