Krakra was a "man remarkable in military affairs" and a high-ranking bolyarin, possibly governor of the Sredets comitatus, under the Tsars Samuil, Gavril Radomir and Ivan Vladislav.
In 1016, another campaign by Basil II was stopped by Krakra at Pernik after an unsuccessful 88-day Byzantine siege.
Following the death of Ivan Vladislav at Dyrrhachium in early 1018, Basil II entered the Bulgarian territory in March 1018 without meeting any resistance.
At Adrianople, Krakra and 35 other bolyari's envoys met with him and after negotiating generous concessions from Basil II, including creating Theme Bulgaria and a separate Bulgarian archbishop chose to join the Eastern Roman Empire.
[1] Basil II met with Krakra personally in Serres and awarded him the title of patrikios.
