The importance of Nitra for the Slavs began to grow in the 8th century and thereafter it evolved to administrative centre of the wider region. Nitra became the center of the Principality of Nitra. Three of the eleven extant copies of the Conversio Bagoariorum et Carantanorum contains a reference to a church consecrated for Pribina in his domain called Nitrava. The problem of Pribina's church and the dating of this event was addressed by numerous scholars, most of them have no doubt about reliability of information and associates this event with Nitra. In 833, Pribina was ousted by the Moravian prince Mojmír I and both regions were united into the early medieval empire of Great Moravia.
