As a year, 590 CE saw several notable developments in late antiquity. In the Sasanian Empire, Hormizd IV died and his son Khosrow II ascended to the throne, beginning a new phase in Persian–Byzantine relations. In the Western Church, Pope Pelagius II died and Gregory I, later known as Gregory the Great, was elected pope in 590, initiating a papacy that would exert considerable influence on the church’s governance, liturgy, and diplomacy in the ensuing centuries.

The events of 590 helped shape the political and religious landscape of the medieval Mediterranean region. The transition in the Sasanian dynasty contributed to ongoing military and diplomatic pressures between Persia and the Byzantine Empire, while Gregory I’s leadership contributed to the strengthening of papal authority and the Christian church in a period of fragmented imperial power.

In summary, 590 is a composite, square-free number with specific mathematical properties, and its associated year is notable for leadership changes in both the Sasanian Empire and the Roman Church, influencing regional dynamics for years to come.
