Saracen Raid on St. Gall

Timeline

1. 900–926Fraxinetum · ProvenceSince the late 9th century, Muslim forces had occupied the mountain fortress of Fraxinetum in Provence, controlling Alpine pass trade routes and launching periodic raids against Burgundy, Switzerland, and northern Italy, becoming a threat to the security of Western Europe's interior.
2. c. 926Monastery of St. Gall · Canton of St. GallenSaracen forces crossed the Alpine passes into northeastern Switzerland, burning and plundering the towns, villages, and farms around the monastery of St. Gall. The monastery itself did not fall entirely due to its strong defenses, but its estates and library suffered severe losses.
3. 926–972Alpine passes · SwitzerlandThe raid prompted Burgundian King Rudolf II and others to strengthen pass fortresses and patrols, and the German Ottonian dynasty also took note of the Saracen threat in southern France. Around 972, a coalition force finally destroyed the Fraxinetum stronghold, ending this era of raiding.
