Simeon was Boris-Michael’s son and was educated in Constantinople. He took power in Bulgaria after his brother Vladimir’s rule. Seals bearing Christ and letters exchanged with Byzantine churchmen show how he asserted authority; they are not neutral portraits of his personality. Ruled Bulgaria from 893 to 927. Under him Preslav was a royal and literary centre. His army won at Achelous in 917. “Golden Age” is a later assessment of literary development, rather than his own label.
