Cathedral chapter
Upon his departure from the office of Prince-elector and archbishop of Cologne, Gebhard Truchsess von Waldburg was elected to fill the position; Gebhard's conversion to Protestantism in 1582, his marriage to Agnes of Mansfeld-Eisleben in 1583, and his refusal to give up the Electorate triggered a schism in the Cathedral chapter of Cologne. After the election of a competing archbishop, Ernst of Bavaria, supporters of the two men pursued a war, called the Cologne War. Salentin participated in this conflict on the side of the Catholic faction of the Cathedral Chapter, and was instrumental in the destruction of Neuss in 1586, in which over 3000 people of the city were killed, and the city itself destroyed.
