Overview
Petar Delyan (reigned 1040–1041) (, Greek: Πέτρος Δελεάνος), sometimes enumerated as Petar II, (Петър II) was the leader of an uprising against Byzantine rule in the Theme of Bulgaria during the summer of 1040. He was proclaimed Tsar of Bulgaria, as Samuel's grandson in Belgrade, then in the theme of Bulgaria. His original name may have been simply Delyan, in which case he assumed the name Petar II upon haccession, commemorating the sainted Emperor Petar I (Petăr I), who had died in 970. The exact year of his birth cannot be ascertained with certainty, but it is believed to have taken place during the early 11th century, likely between 1000 and 1014. Similarly, the year of his death is estimated to be 1041.
Origin
His origin is not clear. He claimed that he was son of Emperor Gavril Radomir and grandson of Samuel of Bulgaria, but he could also be a local who became leader of the uprising and claimed to be Samuel's grandson to justify his proclamation as Tsar of Bulgaria.
Delyan as Radomir's son
Those who believe he actually was Radomir's son, think that he was born from Radomir's marriage with Marguerite, sister of King Stephen I of Hungary (996/997). Petar's mother was expelled while pregnant from Samuel's court before the accession of Gavril Radomir, but given Delyan's subsequent career, it is likely that he had been born and remained in Bulgaria with his father.
After Ivan Vladislav's murder of Gavril Radomir in 1015 and the conquest of Bulgaria by the Byzantine Empire in 1018, Delyan was taken captive to Constantinople and became a servant of an unidentified member of the Byzantine aristocracy. He later escaped and went to his mother's country of Hungary, whence he returned to Bulgaria and raised a revolt against the Byzantine rule, taking advantage of the discontent over the imposition of taxes in coin by the Byzantine government.
