Background: The existence of moral challenges resulting from political, social and economic crises is an inevitable issue of any society and government. Challenges are not urgent, they gradually turn into crises, and can ultimately pose a serious threat to the sovereignty. The Qajar government was in such a situation, especially after the Constitutional Revolution. Political crises and its intertwining with social crises caused moral challenges in this period, which had a great impact on the downfall of the Qajars. In fact, the main issue of this article is to find a suitable answer to the question: "What role and place did the post-constitutional political crises play in overthrowing the Qajar dynasty?" And what moral challenges did these crises create in this period? And how did these challenges manifest themselves?
Conclusion: The results of the study indicate that the concentration of moral challenges, political crises and the emergence of other social crises arising from these crises in Iran, the Constitutional Revolution and the inability of the government to compete with powerful social organizations to provide strategies. More efficient survival for social change led to the tendency of social forces to concentrate power and provided the conditions for the fall of the Qajar dynasty and the creation of a powerful and maximum government to resolve crises.
