Basil II Porphyrogenitus (Greek: Βασίλειος Πορφυρογέννητος Basileios Porphyrogennetos; 958 – 15 December 1025), nicknamed the Bulgar Slayer (Greek: ὁ Βουλγαροκτόνος, ho Boulgaroktónos), was the senior Byzantine emperor from 976 to 1025
…
Basil exacted his vengeance cruelly—he was said to have captured 15,000 prisoners and fully blinded 99 of every 100 men, leaving one one-eyed man in each cohort to lead the rest back to their ruler. A possible reason for this vengeance was that, in Byzantine eyes, the Bulgarians were rebels against their authority, and blinding was the usual punishment meted out to rebels. Samuel was struck down by the sight of his blinded army and died two days later on 6 October 1014 after suffering a stroke.
In what way Bulgaria has claims to this? Greece, Russia, Turkey, Italy, Romania, Albania and Serbia have a more legit claim than Bulgaria.
