Cyril and Methodius both entered the monastery and after the call of Radislav, the prince of Morva, they began to convert in Morva. From the Greek alphabet Cyril created suitable for Slavic language so called Cyrillic letters. This became a base for Slavic language liturgical texts editions. They spread the Gospel in Pannonia, went to Zala castle and Nitra. They met the prince Arpad who asked them to pray for him and his people.
Because of the liturgy in Slavic language they got in conflict with Bavarian clergy (who used Latin), thatís why they were called to Rome and Cyril died there on February 14th, 869 .His tomb is in St. Kelemen basilica in Rome.
In 1980 John Paul II announced him together with Methodius as co-patrons of Europe.
