A research on the historical background of Qom city based on archaeological studies and historical evidence

During the Islamic period, Qom has been known as the second religious center in Iran due to the shrine of Masoumeh (AS). The influence of the religious factor in introducing this city is so that a group of historians believe that before the emergence of Islam, there was no urban base in this region. Despite the scattered research that has been done about the antiquity of Qom, there are many ambiguities about the exact time of the creation of this city and its builders. Therefore, in the present research which is based on the purpose of basic research type and based on the nature and method of historical research type, most of the written sources spoken about the historical background of Qom were carefully studied. In addition, for scientific and more accurate interpretation of the mentioned sources reports and in accordance with them, the results obtained from the archaeological research conducted in the ancient sites of Qom were evaluated. According to the results, Qom plain, which  had been considered by various human societies since the sixth millennium BC,due to its special geographical location, had a relatively prestigious urban base in the late Sassanid period. The Sassanid city of Qom in the year 23 A.H was conquered by the Muslims, however, the first group of Arabs who belonged to the Ash'ari clan settled in this place in the late first century A.H and as a result of their efforts during a century to develop different areas of the region, Qom was recognized as an independent Kūreh in 189 AH.
