Berengar the Wise

Berengar, called the Wise (Catalan: Berenguer el Savi, Latin: Berengarius Sapiens), was the count (or duke) of Toulouse (814–835) and duke (or margrave) of Septimania (832–835). He held the County of Barcelona concomitantly with Septimania.

Berengar was a member of the family of the Unrochids. He was the son of Unruoch II of Friuli and Ingeltrude and brother of Eberhard. His nephew was the Holy Roman Emperor Berengar.

In 814, Louis the Pious installed Berengar as Count of Toulouse in succession to Raymond Raphinel who had been appointed by Charlemagne. He was also a councillor of Pepin I of Aquitaine in 816. In 819, he and Guerin, Count of Auvergne, fought against the usurping Duke of Gascony, Lupo III Centule. Berengar appears as a missus dominicus of Louis in May 825 and then in 827 in the six counties of Rheims, Soissons, Senlis, Beauvais, Laon, and Catolonis and the four bishoprics of Amiens, Cambrai, Saint-Pol-sur-Ternoise, and Noviomacensem.
