magister. The office of archchancellor of the Imperial Kingdom of Italy was at this period regarded as an appanage of the Archbishopric of Cologne, and this was probably the reason why Anno had a considerable share in settling a papal dispute brewing since 1061: relying on an assessment by his nephew Bishop Burchard of Halberstadt, he declared Alexander II to be the rightful pope at a synod held at Mantua in May 1064, and took other steps to secure his recognition against Empress Agnes' candidate Antipope Honorius II. Returning to Germany, however, he found the chief power in the hands of Archbishop Adalbert of Bremen, and as he was disliked by the young emperor, Anno gradually lost ground at the imperial court though he regained some of his former influence when Adalbert fell from power in 1066. In the same year he was able to secure the succession of his nephew, Conrad of Pfullingen, as Archbishop of Trier. By 1072 he had become imperial administrator and thus the second most powerful man, acting as an arbitrator in the rising Saxon Rebellion. In the course of the twelfth and thirteenth centuries the City of Cologne attained great prosperity. Local crafts flourished; the spinners, weavers, and dyers, the woollen-drapers, goldsmiths, sword-cutlers, and armour-makers of Cologne were especially celebrated. No city north of the Alps was so rich in great churches, sanctuaries, relics, and religious communities. It was known as the "German Rome,". With the growth of the municipal prosperity, the pride of the citizens and their desire for independence also increased, and caused them to feel more dissatisfied with the sovereignty of the archbishop. This resulted in bitter feuds between the bishops and the city, which lasted for two centuries with varying fortunes. The first uprising occurred under Anno II, at Easter of the year 1074. The citizens rose against the archbishop, but were defeated within three days, and severely punished. It was reported he had allied himself with William the Conqueror, King of England, against the emperor. Having cleared himself of this charge, Anno took no further part in public business and died in Siegburg Abbey on 4 December 1075, where he was buried. Veneration He was canonised in 1183 by Pope Lucius III. He was a founder or co-founder of monasteries (Michaelsberg, Grafschaft, St. Maria ad Gradus, St. George, Saalfeld and Affligem) and a builder of churches, advocated clerical celibacy
