Without doubt among the most famous members of the clan. As mentioned earlier Robert acted in various roles during his illustrious adventurer career in Italy. He began as a leader of the highway men gang, but became rather soon a mercenary who was hired by different feuding lords of the Southern Italy. In 1059 Robert won a realm of his own then pope Nicholas II declared him a duke of Apulia and Calabria.
Btw. his nickname means “crafty” or “resourceful” and Anna Komnena called him a “sly fox”.
