Bernard I, Count of Comminges

Bernard I (d. between 1145 and 1154) was the first great count of Comminges, succeeding his father Roger III before 1105. He joined the Aragonese Reconquista, fighting at the capture of Tudela in 1114 and at the taking of Zaragoza in 1118.

Around 1120 he married Dias de Samatan, heiress of Muret and Samatan, drawing Comminges into the orbit of Toulouse. He later contested the Val d'Aran with Aragon.

In 1134 Bernard met Alfonso VII of Castile at Zaragoza, probably seeking support, and in 1143 sought an agreement with the Count of Barcelona, apparently securing the valley by 1144.
