Norman Invasions of Greece: What Happened

Between 1081 and 1185, the Normans of southern Italy launched several invasions of Byzantine Greece. The Normans, descendants of Vikings who had settled in northern France, had conquered southern Italy and Sicily, taking the last Byzantine territories there. In 1081, the Norman leader Robert Guiscard and his son Bohemond crossed the Adriatic and besieged Dyrrachium, modern Durrës in Albania. The new Byzantine emperor Alexios I Komnenos was defeated there but fought on, with the help of the Venetian fleet, which he rewarded with valuable trading privileges. The Normans pushed into Epirus and Thessaly, but Robert's death in 1085 ended the campaign. In 1147, the Norman king Roger II of Sicily raided Greece, sacking Corinth and Thebes and carrying off skilled silk workers to Sicily. In 1185, a Norman army captured and brutally sacked Thessaloniki before being defeated. These invasions drained Byzantine resources, and the privileges granted to Venice to gain its help gradually gave Italian merchants a powerful grip on the Byzantine economy.
