The Partition of Armenia and the Survival of the Church
Armenia's political circumstances deteriorated during the later fourth century.
The kingdom remained vulnerable to pressure from Rome and the Sasanian Empire.
In 387, Armenia was divided between Roman and Sasanian spheres of control.
This division weakened the political unity of the Armenian kingdom.
The western and eastern territories followed different administrative and political trajectories.
The End of Arsacid Rule in Eastern Armenia
In 428, the Sasanian authorities ended the Armenian Arsacid monarchy in the eastern portion of Armenia.
This was a major turning point.
The disappearance of the royal dynasty removed a central institution that had previously supported Armenian political identity.
However, the Armenian Church continued to function.
Its bishops, monasteries, educational institutions, and religious traditions provided continuity during a period of political transformation.
The Church as an Institution of Continuity
The Church did not become a complete replacement for Armenian government.
Noble families, regional authorities, and imperial administrations continued to exercise power.
Nevertheless, ecclesiastical institutions helped preserve religious practices, historical memory, education, and written culture.
The development of the Armenian alphabet in the early fifth century further strengthened this role.
