According to a 13th-century source, the "History of the Bishops of Passau and the Dukes of Bavaria", Bishop Reginhar of Passau (r. 818–838) baptized "all of the Moravians" in 831. There is no other information on the circumstances of this mass conversion. Vlasto writes that Mojmír had by that time been converted to Christianity; according to Petr Sommer and other historians, he was also baptized on this occasion. All the same, the "Life of Methodius" narrates that Christian missionaries had by the 860s arrived in Moravia "from among the Italians, Greeks and Germans" who taught them "in various ways". The "Life of Constantine" adds that missionaries from East Francia did not forbid "the offering of sacrifices according to the ancient customs", which shows that pagan rites were continued for decades even after 831.
