3rd century AD

The 3rd century AD (200-299 AD) was a period of significant change for the Roman Empire, marked by political instability, frequent leadership changes, and external threats. Throughout this time, the Empire faced economic difficulties, internal civil wars, and invasions by barbarian groups. Despite these challenges, it also saw developments in art, military restructuring, and the early spread of Christianity. This century is often considered a time of crisis that eventually led to major reforms and the transition from the classical Roman Empire to the later stages of Late Antiquity.
