La liturgie slavonne en Bohême avant charles IV permanence ou renouveau?

This article intends to put into question the disappearance of the Slavonic culture from the interdiction of the Slavonic liturgy which was followed by the expulsion of the monks from Sázava monastery (1096) to the reintroduction of the rite in 1347. On the request of Rastislav of Moravia (846-862), the monks Cyril and Methodius were sent by the Byzantine Emperor Michael III to Velehrad to perfect the Christianization of the country. As the king of a vast empire, Rostislav wanted to escape this German influence, which is why he turned to Byzantium. Cyril and Methodius came from Solon and had a perfect knowledge of Old Slavonic. They managed to create a new liturgy and a new clergy capable of supporting the Moravian State in its political aspirations. Banned in 885 by Pope Stephen V, the Slavonic liturgy was maintained in Bohemia while the duchy had regained its independence (early 10th century), only to be banned in 1096. Through the analysis of a set of sources, our intention is to probe the possible survival of traces of the Slavonic culture between 1096 and 1347.
