Explanation of Shiraz demography in the Mongol period (623 AH-736 AH)

One of the most important consequences of the invasion and conquest of Iran by the Mongols in the 7th century of Hijri (13 AD) was the drastic population fluctuations in different states. In the meantime, Shiraz, as the capital of Pars state under the command of Atabakan Fars, despite the lack of political unity and internal division, was able to escape the Mongol invasion and its consequences. This article aimed to investigate the population structure and the factors affecting the growth and decline of the Shiraz population in a descriptive and analytical method based on library and field studies of cemeteries. The findings of this study show that until the time of Atabak Abu Bakr, Shiraz witnessed an increase in population due to the influx of immigrants from big cities affected by Mongol attacks and internal security. But wars and insecurity that occurred after Atabak Abu Bakr, the attacks of Nekodrian (677 and 680 AH), famine (680 AH), and infectious diseases (698 AH), etc. reduced the population of Shiraz and the population began to decline. However, it was crowded and prosperous during the time of Abu Ishaq Inju (752-725) and Ibn Battuta Shiraz.
