Cyril and Methodius from Bular Site
In 886, invited by Prince Boris-Michael, the disciples of the Slav apostles Cyril and Methodius, who had been sent away from Greater Moravia by that time, arrived in Bulgaria. They were received with great honours by the Bulgarian governor of Belgrade (Serbia's capital today) as soon as they had reached the border. With the approval of Boris I, two spiritual centres of tremendous significance for Slavic culture were formed in the capital city of Pliska, as well as in the other central town - Ohrid, in Macedonia. Only in Ohrid, in the course of 7 years as many as 3500 students were educated.
