Basil II Porphyrogenitus, nicknamed the Bulgar Slayer, was the senior Byzantine emperor from 976 to 1025. He and his brother Constantine VIII were crowned before their father Romanos II died in 963, but they were too young to rule. The throne thus went to two generals, Nikephoros Phokas and John Tzimiskes before Basil became senior emperor, though his influential great-uncle Basil Lekapenos remained as the de facto ruler until 985. His reign of 49 years and 11 months was the longest of any Roman emperor.

Constantine VIII
(Greek: Κωνσταντῖνος, Kōnstantinos; 960 – 11/12 November 1028) was de jure Byzantine emperor from 962 until his death. He was the younger son of Emperor Romanos II and Empress Theophano. He was nominal co-emperor since 962, successively with his father; stepfather, Nikephoros II Phokas; uncle, John I Tzimiskes; and brother, Basil II. Basil's death in 1025 left Constantine as the sole emperor. He occupied the throne for 66 years in total, making him de jure the longest-reigning amongst all Roman emperors since Augustus.
