"Bremen's" remaining suffragan sees at that time were only existing by name, since insurgent Wends had destroyed the so-called Wendish dioceses of Oldenburg-Lübeck, Ratzeburg and Schwerin and they were only to be reestablished later. At the stripping of the Duchy of Saxony (7th century - 1180) in 1180 all of these suffragan bishops achieved for parts of their diocesan territories the status of imperially immediate prince-bishoprics. The Bishopric of Livonia (first at Uexküll then Riga) was a suffragan of Bremen in the years 1186–1255.
