Counts of Marsi

The Conti di Marsi, the Counts of Marsi, were a lineage of Frankish origin who figured among the main feudal lords of Abruzzo, part of the Duchy of Spoleto in southern Italy, during the eleventh and twelfth centuries.

With Celano as their main seat, they ruled over a territory that stretched from Lake Fucino as far as the Peligni.

The conti maintained that they descended from Bernard, king of Italy, grandson of Charlemagne, who had been dethroned and blinded by his uncle, Louis the Pious, in 818. This Carolingian connection cannot now be proved or disproved. It is more certain that they descended from a certain Berardo who was called "Francesco" because he came from Francia, who came to Italy with Hugh of Provence, King of Italy from 924 until his death in 948. According to the Chronicle of Monte Cassino, the first known member of this family, Azzo, Berardo's uncle, was a Burgundian count. The conti do Marsi considered themselves Berardinga, "Berardings" or, by modern historians, Bosonids.

The chronicler of Monte Cassino who records this decisive event was of the house himself, Leo Marsicanus (1046, Marsica — 1115 or 1117, Ostia) (meaning "of the Marsi"), also known as Leone dei Conti di Marsi; Leo became a monk in Monte Cassino around 1061 and served as a cardinal in the early twelfth century.

As Azzo and Berardo arrived in Italy with Hugh in 926, it is likely that these Burgundian counts originated in the Kingdom of Arles, originally the southern part of the kingdom of Burgundy, where Hugh's family originated. Though the name Azzo is familiar today from the Este family, later rulers in Ferrara and Modena, the name was not unusual in northern Italy at the time.

Three sons of Berardo are recorded in the Chronicle of Monte Cassino, Rinaldo and Oderisio, both counts of Marsi in a charter of 981, and Azzo II, whose son Lupo was abbot of Montecassino. Abbot Lupo's first cousin Oderisio and his wife Gibberga were joint benefactors of Monte Cassino.

Powerful nobles like the conti di Marsi expected to place their sons in commanding positions in the church hierarchy as well. The chronicler Amatus of Montecassino names Oderisius, the oldest brother of Berard, Count of Marsia, against whom Berard rebelled, specifying that he had seven sons, two of whom were bishops, a third a monk and a cardinal at Rome. This Bernard, who died after 1070/73, "through insatiable greed and desire for wealth fell out with his brother" the chronicler reports.

Dissension among the counts of Marsi enabled the a new power to be reckoned with in the south of Italy, that of Robert Guiscard, whose base of power lay to the south, in Apulia and Calabria, to defeat the individual members of the Berardings and establish Norman power in southern Italy.
