Rainald was the elder son of Frederick I, count of Astenois, and Gertrude, daughter of Rainald II, count of Toul. He and his brother Peter of Dampierre took part in the crusade in the army of their kinsman Godfrey of Bouillon, duke of Upper Lotharingia. Rainald was a prominent man of the second rank in the crusade, and commanded a division of the united crusader army at the Great Battle of Antioch (28 June 1098). He returned home after the crusade, and died sometime before 1124.
