Byzantine Empire John I Tzimisces

ΙΩΑΝΝΗΣ Α ΤΣΙΜΙΣΚΗΣ - John I Tzimisces​

One of the most dynamic Byzantine rulers, John Tzimisces came from a military family and was made commander of the Eastern armies by the Emperor Nicephorus II. Capable and ambitious, he became the lover of the emperor's wife, Theophano, and together they plotted the murder of Nicephorus in AD 969. Once Nicephorus was out of the way, John had Theophano banished, married the daughter of Constantine VII, and ascended the throne as senior emperor and protector of the young Basil II and Constantine VIII. Despite its tawdry start, his rule was brilliantly successful on all fronts. Personally leading the now formidable Byzantine army, he dealt heavy defeats to the Russians, Bulgarians and Arabs. By AD 975 he was in striking distance of Jerusalem and even Baghdad, and the Empire was stronger than it had been since the days of Justinian. His impressive reign was cut short by his death at age 51 in AD 976, either due to typhoid or poisoning.
