Siegfried II of Westerburg

In March 1287, he led the opposition the taxation of the clergy proposed by the cardinal legate Giovanni Boccamazza at the Synod of Würzburg.

In July 1287, he freed the city of Cologne, after receiving a loyalty oath from its citizens, from paying duties to finance his war expenses in the Limburg succession conflict.

Siegfried lost the battle, which also involved citizens from Cologne led by Gerhard Overstolzen and from Berg under the leadership of Walter Dodds.

He had to pay reparations of 12,000 marks (about three tons of silver) to the Count of Berg, cede areas (among others, Lünen with all episcopal rights, Westhofen, Brackel, Werl, Menden, Isenberg, and Raffenberg) and the (sub-) Vogtship over the Diocese of Essen to Eberhard II, Count of the Mark (who thereby benefited most from the victory at Worringen), pledge the town of Deutz and some castles, and tear down other castles like Worringen, Zons, and Volmarstein.

It specified that the distinguished citizens (oppidani maiores) should choose twelve suitable men, the best the city had to offer, whose decisions would be binding for the whole citizenry.

In the upcoming election of the King of Germany in 1292, Siegfried favored Count Adolf of Nassau, his brother-in-law, to enable the Archbishop to recover from his vast concessions.
