Explanation and comparison of the security position of castles in the development of the Zandiyeh period (with emphasis on Kermanshah Castle)

During the Zand period (1751-1794), the spread of firearms, especially cannons, did not have much impact on the conquest of strong fortresses. Given the lack of comprehensive research on fortresses during the Zandiyeh period, the research findings indicate that urban and rural fortresses were the most important sites for the accumulation of resources and political power, attracting pretenders to the throne. Kermanshah Fortress was considered the most valuable fortress in the country due to its rich military stores, which led to the longest period of siege and field battles.
