Peace of Acilisene

From Wikipedia, the free encyclopedia
The division of Armenia after the Peace of Acilisene.

The Peace of Acilisene was a treaty between the Eastern Roman Empire under Theodosius I and the Sasanian Empire under Shapur III, which was resolved in 384 and again in 387.[1]


The treaty, resolved in 384 and later in 387, divided Kingdom of Armenia between the Eastern Roman Empire and the Sasanian Empire.[2] The Sassanids received the larger share called Persarmenia, while the Romans retained Sophene and a smaller portion of Armenia (called Lesser Armenia).[1][2][3] This also created a new boundary line between the two empires, running from Erzurum to Mush.[2]

Through this treaty, the Eastern Roman Empire admitted the loss of the Kingdom of Iberia to the Sasanians.[1] During this period, Sassanian influence grew once again in eastern Georgia, and Zoroastrianism spread as far as Tbilisi, [2] becoming "something like a second established religion of Iberia" until around mid-fifth century.[4]
