March of Turin

The march of Turin or marca Arduinica (sometimes "march of Susa") was a political entity with existed in medieval Italy from the mid tenth century. It consisted of lands in Piedmont, stretching across the Po Valley from the Western Alps in the north, to the Ligurian Sea. It included the counties of Turin, Auriate, Albenga and, probably, Ventimiglia. The centre of the march was the city of Turin.[1]

The regnum Italicum (Kingdom of Italy) into three marches, which were named after their three ruling dynasties:[2]

Rule by the Arduinici

Arduin Glaber was invested as count of Turin in 941 by Hugh of Italy. Arduin had captured Turin and the Susa Valley from the Saracens.[3] In 964, Arduin was appointed margrave of Turin by Emperor Otto I.[4] The mark of Turin continued to be ruled by members of the Arduinici thereafter. Arduin Glaber's son Manfred I succeeded him, and his son, Ulric Manfred II, succeeded him. Ulric Manfred II had no male heir, however, so he left the march to his daughter Adelaide.[5] Although Adelaide was the de facto ruler, the margravial title could not be held by a woman. Adelaide’s husbands, then sons, and finally grandson-in-law were successively invested as margrave of Turin. These men were not members of the Arduinici dynasty.

Breakup of the march

After Adelaide’s death in 1091, the march of Turin broke up. Comital authority in the city of Turin was invested in the bishop of Turin (1092) and the city itself became a commune (1091). In 1092 Emperor Henry IV appointed his son Conrad as margrave of Turin (Conrad was Adelaide’s grandson via her daughter Bertha of Savoy).[6] Although Conrad attempted to gain control of the march, his power was never effectual and the title was largely nominal.[7] Instead, the northern part of the march of Turin was absorbed into Savoy, which was ruled by another of Adelaide’s grandsons, Humbert II (many centuries later, Turin became the capital of this dynasty). To the south, lands with had comprised the march of Turin were annexed by Adelaide's nephew, Boniface del Vasto.[8]
