Justin II, born in the year five hundred twenty, ascended to the throne as the Eastern Roman emperor in five hundred sixty-five, ruling until five hundred seventy-eight. He was the nephew of the illustrious Justinian I and married to Sophia, who was the niece of Justinian's wife, Theodora.
Upon inheriting a vast but overstretched empire, Justin II faced the daunting challenge of governing with significantly diminished resources compared to his predecessor. His reign was marked by a decisive shift in foreign policy; he terminated the payment of tributes and adopted a confrontational approach towards neighboring states.
This hardline stance led to the resurgence of hostilities with the Sassanid Empire in five hundred seventy-two and the commencement of the Byzantine-Lombard wars in five hundred sixty-eight. These conflicts would ultimately result in the loss of substantial Roman territories in Italy by the year seven hundred fifty.
Despite his ambitions, Justin II's military campaigns against the Persians were largely unsuccessful. As his reign progressed, he struggled with severe mental illness, which further complicated his ability to govern effectively.
