Bishop Anno II came from a noble family from the Swabian Alps. Kaiser Heinrich III, whom he served as court curate, named him Archbishop of Cologne in 1056. After the Emperor's death he abducted Heinrich's son along with the imperial insignia in 1062 in order to escape from the influence of the boy's mother Agnes. ("The Coup of Kaiserswerth") In 1072 he became imperial administrator and thus the second most powerful man. Under Anno many Cologne churches were renovated and expanded. He was also known as a passionate collector of relics for his diocese. He built the Church of St. Maria ad gradus and the Siegburg Abbey. In terms of city politics, his tenure was marked by disagreements with the citizens. When he requisitioned the ship of a Cologne merchant for one of his guests, there was a rebellion and he had to flee the city. Upon returning he had the houses of his chief opponents plundered because they refused to ask his pardon. Soon after his death he was venerated as a saint, especially in his foundations. He is the patron of gout sufferers.
