Italy

In 860, according to an account by the Norman monk Dudo of Saint-Quentin, a Viking fleet, probably under Björn Ironside and Hastein, landed at the Ligurian port of Luni and sacked the city. The Vikings then moved another 60 miles down the Tuscan coast to the mouth of the Arno, sacking Pisa and then, following the river upstream, also the hill-town of Fiesole above Florence, among other victories around the Mediterranean (including in Sicily and Nekor (Morocco), North Africa).

Many Anglo-Danish and Varangian mercenaries fought in Southern Italy, including Harald Hardrada and William de Hauteville who conquered parts of Sicily between 1038 and 1040, and Edgar the Ætheling who fought in the Norman conquest of southern Italy. Runestones were raised in Sweden in memory of warriors who died in Langbarðaland (Land of the Lombards), the Old Norse name for southern Italy.

Several Anglo-Danish and Norwegian nobles participated in the Norman conquest of southern Italy, like Edgar the Ætheling, who left England in 1086, and Jarl Erling Skakke, who won his nickname ("Skakke", meaning bent head) after a battle against Arabs in Sicily. On the other hand, many Anglo-Danish rebels fleeing William the Conqueror, joined the Byzantines in their struggle against the Robert Guiscard, duke of Apulia, in Southern Italy.
