Gebhard Truchsess von Waldburg, Archbishop of Cologne (died 1601)

Gebhard Truchsess von Waldburg was the archbishop-elector of Cologne from 1577 to 1588. After pursuing an ecclesiastical career, he won a close election in the cathedral chapter of Cologne over Ernst of Bavaria. After his election, he fell in love with and later married Agnes von Mansfeld-Eisleben, a Protestant canoness at the Abbey of Gerresheim. His conversion to Calvinism and announcement of religious parity in the electorate triggered the Cologne War.
