The Impact of Nayebian Revolt on the Educational Process in Kashan

The Courier Office was one of the important offices in the administrative organization of Muslim governments in the Persian Middle Ages. Among other things, it functioned as a center for obtaining and supplying information related to the national security. This office found an eminent status in its governmental relations in a way that it was regarded as "the eye and the ear of government" throughout the State territory since its activities had been expanded to cover various spheres. The management of extended governmental territories made it necessary to obtain information on different incidents occurring in provinces and passing it on to the central government, to monitor the performance of officials in their governmental positions, to provide post services, and to embark on espionage activities. The above-mentioned activities were some of the duties of the Courier Office during the Middle Age of Iranian history. The present study tries to expound on the concept of Courier and its derivatives in a historical-analytical manner, focusing on security-related functions of the Courier Office in the central governments of Iran. Findings of the present study show that the extended activities of the Courier Office were highly important in a way that the continuation, or else the extinction of governments were directly dependent on the proper functioning of this institution.
