Deaths of Justin II and Tiberius II Constantine

Justin II served as the Byzantine Emperor from 565 until his death. His reign was marked by military conflicts and internal strife, particularly due to his deteriorating mental health, which began to manifest in fits of insanity. This condition significantly impacted his ability to govern effectively, leading to a reliance on his general, Narses, and other advisors to manage state affairs. The instability during Justin's reign contributed to challenges in maintaining the empire's borders and managing its finances. Following his death, the transition of power to Tiberius II Constantine was crucial for the continuity of the Byzantine Empire. Tiberius II, who had been appointed as co-emperor, took over the leadership amid ongoing military pressures and economic difficulties. His reign focused on stabilizing the empire and addressing the issues left unresolved by Justin II.
