Methodius now continued the work among the Slavs alone; not at first in Great Moravia, but in Pannonia (in the Balaton Principality), owing to the political circumstances of the former country, where Rastislav had been taken captive by his nephew Svatopluk in 870, then delivered over to Carloman of Bavaria, and condemned in a diet held at Regensburg at the end of 870. A the same time, the East Frankish rulers and their bishops decided to remove Methodius. The archiepiscopal claims of Methodius were considered such an injury to the rights of Salzburg that he was captured and forced to answer to East Frankish bishops: Adalwin of Salzburg, Ermanrich of Passau, and Anno of Freising. After a heated discussion, they declared the deposition of the intruder, and ordered him to be sent to Germany, where he was kept prisoner in a monastery for two and a half years.
