The Concilium Germanicum was the first major Church synod to be held in the eastern parts of the Frankish kingdoms. It was called by Carloman on 21 April 742/743 at an unknown location, and presided over by Boniface, who was solidified in his position as leader of the Austrasian church. German historian Gunther Wolf judges that the Concilium was the high point in Boniface's long career.[1]
