The Development of Hamadan Transportation Lines in the Middle Ages and its Position in the Development of Residential Centers

Dargazin was one of the politically and culturally significant regions of Iran in the past, and its historical monuments and mounds shows the importance of this area. Why was Dargazin important in the post-Islamic era and what was the role of the routes in the formation of settlements and the cultural development of this region? To answer these questions, the present article looks for the historical background of the routes, and its role in the expansion of the settlements, and the cultural growth of Dargazin in the post-Islamic era. The geographic location of Dargazin (being on the side of the main roads), having fertile and flat lands, and being at the skirts of the Kharaqan mountains (which is a geopolitical advantage), developed this area, as a transit point for commercial caravans and the residence of several groups of people. At the present time, Dargazin locates on the side of the roads to Zanjan, Markazi, and Qazvin provinces, and in the past, the two main branches of the Silk Road surrounded it from east and west. The study shows that most of the habitats of this area have been located along these routes.
