Rudolf III of Montfort

Rudolf III of Montfort (born 1260–1275, died March 1334) was a Swabian count's son who became bishop of Chur and Konstanz. A canon and later provost at Chur, he was elected its bishop in 1322, but Pope John XXII made him bishop of Konstanz, while he administered Chur until 1325.

He backed the Habsburgs but sided with the pope against Emperor Louis IV, whose regalia he accepted in 1332. The pope excommunicated him in 1333, and he died at Arbon in 1334, buried in unconsecrated ground.
