Zweder van Culemborg

Who is Zweder van Culemborg?

Zweder van Culemborg was bishop of Utrecht during the Utrecht Schism.

After the death of bishop Frederik III van Blankenheim in 1423, a succession-conflict had emerged between the two candidates for the bishopric's seat; Zweder van Culemborg and Rudolf van Diepholt. In order to end the conflict, pope Martin V nominated his own favourite, Rhabanus von Helmstatt to the bishopric in 1422. But Rhabanus declined the nomination, after which the pope appointed Zweder on 6 February 1425. Rudolf refused to accept this, and Zweder had to use violence to get his authority recognised. However, he was driven out of the city of Utrecht in 1426 by his opponents. As a result Rudolf was excommunicated by the pope, but he nonetheless managed to maintain himself, even though Zweder was initially supported by the duke of Guelders and Philip the Good, who was also count of Holland. But Rudolf was able to sign treaties with neighbouring rulers, after which pope Eugene IV, Martin V's successor, appointed Zweder to the titular bishopric of Caesarea and recognised Rudolf as bishop of Utrecht on 10 December 1432. Zweder complained about this at the Council of Basel, that ruled in his favor, but it was all for naught as Zweder died shortly after.
