Career
According to the chroniclers, George Sursuvul was a father of Simeon I"s unnamed wife, brother of Peter I"s wife Maria Sursuvul, and also Peter I"s maternal grandfather. George Sursuvul retired from the regency after concluding a peace treaty with the Byzantine emperor Romanos I Lekapenos, one of which terms was a marriage of George Sursuvul"s grandson Peter I to Byzantine Emperor"s granddaughter Maria Lakapenos (renamed Eirene). George Sursubul, heading a delegation of Simeon I"s brother-in-law Symeon, Calutarkan, courtier Sampses, and numerous nobility, met with Romanus I in 927 and concluded the peace treaty which ended the Byzantine–Bulgarian war of 913–927.
Afterwards, he presided at the marriage ceremony as a witness on the bridegroom’s side, with his counterpart on the Byzantine side being the Byzantine Prime Minister.
The timing of his retirement from the post of the Prime Minister is unknown. The historian Steven Runciman cites description of George Sursuvul as an ambassador to the Byzantine Court left by Otto I"s Frankish abassador Bishop Liudprand of Cremona, offended that Bulgarian ambassadors at Constantinople had precedence over all other ambassadors: his head was shaven, he wore a brass belt and trousers.
