Overview
Conrad of Wittelsbach (c. 1120/1125 – 25 October 1200) was the Archbishop of Mainz (as Conrad I) and Archchancellor of Germany from 20 June 1161 to 1165 and again from 1183 to his death. He was also a cardinal of the Roman Catholic Church.
The son of Otto IV, Count of Wittelsbach, and brother of Otto I of Bavaria, he studied in Salzburg and Paris. At the Council of Lodi in 1161, Frederick Barbarossa appointed him archbishop of Mainz to end a schism between Rudolf of Zähringen and Christian von Buch in that see. At that same council, Barbarossa appointed Victor IV antipope in opposition to Pope Alexander III. After Victor's death in 1164, Rainald of Dassel, the archbishop of Cologne, chose as antipope Paschal III at Lucca. Conrad refused to support the new antipope and consequently fell out with Barbarossa. He fled to France and then Rome in 1165 and his see was bestowed on Christian von Buch, though Alexander III still recognised him as legal archbishop. On 18 December, the pope made him cardinal priest of San Marcello al Corso and then cardinal bishop of Sabina. The pope later created him bishop of Sora in Campania. Conrad fled before Christian took Rome with an imperial army.
By the Treaty of Venice of 1177, the pope was constrained to recognise Christian as the legitimate archbishop of Mainz, but Conrad was compensated with the archdiocese of Salzburg (as Conrad III). Conrad never, however, ceased to regard himself as anything but the rightful archbishop of Mainz. When Christian died in 1183, Conrad could again assume his archiepiscopal responsibilities in that city, which, in 1160, had been deprived by the emperor of its charter for the murder of the archbishop Arnold of Selenhofen. The fortifications had then been levelled, but Conrad rebuilt them and renovated Mainz Cathedral. The Diet of Pentecost 1184 on the Maarau, called the "largest feast of the Middle Ages", also fell under his aegis.
In April or May 1187, at the Diet of Gelnhausen, Conrad convinced his fellow bishops to support the emperor's cause against Rome. In March 1188, a Court of Christ was held in Mainz at which the Third Crusade was announced. Conrad led an army on Crusade in 1197, the same year the Emperor Henry VI died. He left his lands on 17 April 1197.
