Venetian fleet defeated Muslims besieging Bari. After the Aghlabids were defeated in Ifriqiya as well, Sicily fell in the 10th century to their Fatimid successors, but claimed independence after fights between Sunni and Shia Muslims under the Kalbids. Raids in Piedmont After they had conquered the Visigoth Kingdom in Spain (729–765), the Arabs and Berbers from Septimania and Narbonne carried out raids into northern Italy, and in 793 again launched an offensive into northwestern Italy (Nicaea 813, 859 and 880). In 888, Andalusian Muslims set up a new base in Fraxinet near Fréjus in French Provence, from where they started raids along the coast and in inner France. In 915, after the Battle of Garigliano, the Muslims lost their base in southern Lazio. In 926 King Hugh of Italy called the Muslims to fight against his northern Italian rivals. In 934 and 935 Genoa and La Spezia were attacked, followed by Nicaea in 942. In Piedmont the Muslims got as far as Asti and Novi, and also moved northwards along the Rhône valley and the western flank of the Alps. After defeating Burgundian troops , in 942–964 they conquered Savoy and occupied a part of Switzerland (952–960) . To fight the Arabs, Emperor Berengar I, Hugh's rival, called the Hungarians, who in their turn devastated northern Italy. As a result of the Muslim defeat at the Battle of Tourtour, Fraxinet was lost and razed by the Christians in 972. Thirty years later, in 1002, Genoa was invaded, and in 1004 Pisa. Pisa and Genoa joined forces to end Muslim rule over Corsica (Islamic 810/850-930/1020) and Sardinia. In Sardinia in 1015 the fleet of the Andalusian lord of Dénia come from Spain, settled a temporary military camp as a logistic base to control the Tyrrhenian Sea and Italian peninsula, but in 1016 the fleet was forced to leave its base due to the military intervention of maritime republics of Genoa and Pisa. Sicily under the Normans The cultural and economical bloom in Sicily that had started under the Kalbids was interrupted by internecine fights, followed by invasions by the Tunisian Zirids (1027), Pisa (1030–1035), and the Romans (1027 onwards). Eastern Sicily (Messina, Syracuse and Taormina) was captured by the Byzantines in 1038–1042. In 1059 Normans from southern Italy, led by Roger I, invaded the island. The Normans conquered Reggio in 1060 (conquered by the Romanin 1027). Messina fell to the Normans
