This era was characterized by political chaos, military defeats, economic decline, and social unrest, which collectively threatened the very existence of the empire. As a result of these challenges, the empire experienced numerous changes in leadership and a fragmentation of its territories, ultimately leading to significant reforms under the Tetrarchy.
