Conrad III of Dhaun

[1] In August 1421, Conrad, together with Archbishop Dietrich II of Cologne and Elector Palatine Louis III, joined the Second anti-Hussite Crusade.

In 1429, Conrad travelled to Bratislava, where he participated in his capacity as Archchancellor in the negotiations between Emperor Sigismund and the Hussite leaders.

The archbishops of Mainz had been struggling with the Landgraviate of Hesse over territorial dominance in the area for two centuries.

In 1427, Conrad once again declared war on Hesse, about a sum of money due from the mortgage on the County of Waldeck, and also to support his close friend co-adjutor Herman II of Buchenau in a conflict with Prince-abbot John I of Fulda monastery.

An army of 600 cavalry and additional infantry led by Count Gottfried of Leiningen (a younger relative of the cathedral dean of the same name), attacked northern Hesse from Fritzlar, an exclave of Mainz, and devastated the area around Gudensberg, Felsberg and Melsungen.

His grave monument was probably sculpted by Madern Gerthener, whom Conrad knew from his period as pastor as St. Bartholomew.

Gerthener had also sculpted the grave monument of Conrad predecessor, John II of Nassau.
