Due to being largely limited to their possessions in the German kingdom, the two titles were combined during the incumbency of "Deutschmeister" Walter von Cronberg, who was also appointed "Hochmeister" by Emperor Charles V in 1527. The administrative seat was moved to Mergentheim Castle in Franconia. The "Hoch- und Deutschmeister" were ranked as ecclesiastical Princes of the Holy Roman Empire until 1806; when Mergentheim fell to the newly established Kingdom of Württemberg, their residence was relocated to the "Deutschordenshaus" in Vienna. The dual-title lasted until in 1923 the last secular Grand Master Archduke Eugen of Austria resigned from office.
