Continuing the policy of friendship with the Holy Roman Emperor, he accompanied the Emperor Henry V to the Diet of Worms of 1122, where the Investiture Controversy was resolved.

He had stormy relations with the episcopates of his realm: fighting with Stephen of Bar, bishop of Metz, and Adalberon, archbishop of Trier, both allies of the count of Bar, whose claim to Lorraine against Simon's father had been quashed by Henry V's father Henry IV. Though Adalberon excommunicated him, Pope Innocent II lifted it. He was a friend of Bernard of Clairvaux and he built many abbeys in his duchy, including that of Sturzelbronn in 1135. There was he interred after his original burial in Saint-Dié.
