シメオン1世
Peter I was the son of Simeon I of Bulgaria by his second marriage to the sister of George Sursuvul. Peter had been born early in the 10th century, but it appears that his maternal uncle was very influential at the beginning of his reign. In 913 Peter may have visited the imperial palace at Constantinople together with his older brother Michael. For unspecified reasons, Simeon had forced Michael to become a monk and had named Peter as his successor.
