Occo of Schleswig

Occo of Schleswig (also Aage, Aagge, Ogge) was the bishop of the Diocese of Schleswig between 1141 and 1145 and again from 1161 to 1167.

The chapter of Schleswig Cathedral elected Occo bishop in 1138, after Bishop Rike had been elected the new bishop of Roskilde. However, Eric III Lamb imposed his chaplain Hermann, who was born in the Holy Roman Empire. So Esbern's relatives protected him and killed Nicolaus. Fearing the royal revenge Esbern fled to Saxony, where he died in 1161.

King Valdemar I the Great then reappointed Occo as bishop. This made Eskil inflicting the ban on Occo, but due to internal quarrels in the church the bishop of Schleswig managed to stay in office until his death. Starting in 1161 Occo built a new Gottorp Castle, replacing the destroyed one, however, on another site.
