At the end of the 16th century, under the guidance of Johann Marbach, Alsace adopted the orthodox Lutheran ideas contained in the Formula of Concord of 1577. Even within the cathedral chapter of the Strasbourg diocese, Lutheran capitular canons formed the majority (Strasbourg Chapter Strife, 1583–1604). In 1592 this majority elected John George of Brandenburg as the first Lutheran prince-bishop of Strasbourg.
