Drogo Hauteville Count of Apulia
Drogo of Hauteville, called Dreux or Drogon de Hauteville in French and Drogone d'Altavilla in Italian, succeeded his brother, William Iron Arm, with whom he arrived in southern Italy c.1035, as the leader of the Normans of Apulia. He received Venosa in the partition of Melfi.
In 1047, Emperor Henry III confirmed him in his position and gave him the titular Dux et magister Italiae comesque Normannorum totius Apuliae et Calabriae, translating Duke and Master of Italy and Count of the Normans of all Apulia and Calabria, the first legitimate comital title for a Hauteville. During his reign, his half-brother Robert Guiscard arrived in the Mezzogiorno (c.1047). He could not control his barons and stem the tide of brigandage and feudal warfare paralysing the Mezzogiorno. In 1051, Pope Leo IX received his promise to stop the Normans pillaging, but he was assassinated later that year (probably by a Byzantine conspiracy) and was succeeded by his younger brother Humphrey after a brief interregnum.
He was married to Gaitelgrima, a daughter of Prince Guaimar III of Salerno, who later married Humphrey.
