Through the history، transmission and propagation of human groups have happened according to political-military aims and activities, nowadays called Diaspora. In Sasanian era many individuals and groups of people were transmitted or exiled. These compulsory immigrants were the victims of Sasanian pragmatist policies. But what paved the way for this crisis, were the progressive contests and the tendencies to show the power on both Sasanian and Byzantine empires in the region. Sasanians continued Diasporas and exile policy inside and outside their territory. They proceeded to do so through political pressures and violent repression. By continuing this procedure، Sassanins aimed to weaken the military forces of the nations and deprive the rivals of being supported ethically or use the abilities and skills of deportees in reconstructive and economic affairs, which was entirely proceeded intentional and wisely. Other dimension of this phenomenon was the increase of Christian activities and the spread of Christianity in Sasanian territory which was followed by dissatisfaction of Zoroastrian priests. For this reason, this survey aims to investigate this social crisis and the role of Sasanian kings in resumption of this policy and its results and consequences.
