The Congress of Ems was a meeting set up by German and Austrian Catholic archbishops, and held in August 1786 in Bad Ems, near Koblenz. Its object was to protest against papal interference in the exercise of episcopal powers, and to fix the future relations between the participating bishops and the Pope. Representatives of the German Archbishops Friedrich Karl von Erthal of Mainz, Maximilian Franz of Cologne, Clemens Wenceslaus of Trier, and Hieronymus von Colloredo of Salzburg all took part.
