What are the reasons of the decline of Persia?

The decline of Persia, particularly during the Qajar and Pahlavi periods, can be attributed to several key factors. Internal strife, including political corruption and social unrest, weakened central authority and led to fragmentation. Additionally, foreign invasions and influence, particularly from Russia and Britain, undermined Persia's sovereignty and economic stability. Lastly, the rise of nationalism and modern political movements further challenged traditional power structures, contributing to the empire's decline.
