Archbishop Methodius died on April 6, 885. Led by Bishop Wiching of Nitra, Methodius's opponents took advantage of his death and persuaded Pope Stephen V (r. 885–891) to restrict the use of Old Church Slavonic in the liturgy in the bull "Quia te zelo". Bishop Wiching even convinced Svatopluk to expel all Methodius's disciples from Moravia in 886, thus marring the promising literary and cultural boom of Central European Slavs - the Slovaks took nearly a thousand years to develop a new literary language of their own.
