With the entrance of the Arab Moslems into Iran and the first-degree Sasani wealthies extinction, the peasants as local governors and village rulers (kadag-xwadāy) undertake Iran’s public leadership. And because they did not have any hope for Sasani’s old system to come back, they decided to establish a relationship with Islamic forces. Also Arab Moslems, who at first had required the peasants to help them supervise country, made peace with the local ruler clique and established them in charge of the work they were doing in the Sasanid period. In this process, the peasants in the west and the east part of the Sasanid territory were different in terms of acceptance or non-acceptance of Islam and Arabic language. That was influenced by the time of conquests and geographical distance from the capital of Islamic caliphate. Entrance of Arab and Turks in the first and third century was the most significant element of the peasants’ decline in Iran. The approach of this stady and its methods in gathering data are historical.
