The Consequences of the Mongol Invasion and Ilkhanate Rule on the Scientific Tradition in Iran

The Mogul invasion and their rule over Iran has always been mentioned  as the cause of the decline of knowledge in this land. The present study seeks to find the impact of the Mongol invasion and the rule of Ilkhans on the scientific tradition in Iran, using the descriptive-analytical approach, and also to answer the questions such  as what have changed in the scientific tradition in compare with  the past ages and what have been the consequences of those changes? The result of this study shows that with the rule of the Ilkhans, the scientific tradition in Iran has been influenced by several factors, such as the religious tolerance of the Ilkhanates and the rationalist's domination, on scientific and educational institutions. Therefore, along with religious studies, the intellectual sciences also were the focus of attention of the scholars of this period. And so, it was one of the flourishing periods of Iranian history in terms of building scientific and educational centers and reviving scientific activities, especially in the field of intellectual sciences.
