Abstract
One of the most important changes in the structure and function of the state in the modern era can be seen in its role and position in the field of social policy, to the extent that it is currently the central issue of the state.Social policy is a planned and deliberate intervention that the state does through the redistribution of resources to achieve important social goals, and by this means, it tries to improve the environment by properly implementing this policy provide political and social stability and prevent the emergence of political and social crises. The purpose of this article is to investigate and analyze the function of social policy in the governments of the Islamic Republic of Iran. Therefore, the question of the article is, what was the functional status of social policy in the governments of the Islamic Republic of Iran, and what strategies need to be adopted in this area? The hypothesis of the article is that the social policy in the governments of the Islamic Republic was disorganized and inefficient, which factors such as: the rentier nature of the state, the domination of the political over the social, the idealism of the policy system, etc, have played an effective role in creating this situation. In general, the failure of this policy in establishing social justice in the country has had a negative impact on the confidence of a significant part of the Iranian people towards the political system and caused the emergence of political and social crises in this period. However, with all this, the Islamic Republic system can improve the efficiency of social policy and strengthen people's trust in the state by removing and correcting these factors and adopting rational and efficient strategies. It should be noted that, in terms of methodology, this article is qualitative and analytical and applied-developmental.

Introduction
One of the most important changes in the structure and functioning of the state in the modern era can be seen in its role and position in the field of social policy formulation, to the extent that today it is considered a central issue of the state. Social policy is a planned and deliberate intervention that the state carries out through the redistribution of resources to achieve important social goals, and by this means it tries to provide the grounds for political and social stability and prevent political and social crises by implementing this policy in a desirable manner. The important point from the perspective of this article is that during the Islamic Republic of Iran, and despite the revolutionaries' emphasis on formulating a comprehensive social policy and eliminating injustice and social inequalities, as well as some measures taken by the governments of the Islamic Republic, we witness the inefficiency of social policy formulation and the lack of serious attention to this area. The main point here is that this situation has negatively affected the trust of a significant part of the Iranian people in the political system and the national society, and as a result, it has caused protests and political and social crises in Iran in the last two to three decades. In the opinion of this article, the continued inefficiency of social policy and the lack of solutions to correct it can lead to more serious socio-political challenges. Accordingly, in today's Iran, the desirable and correct implementation of social policy is one of the necessities facing the Islamic Republic system in order to strengthen the relationship between the people and the state and prevent the emergence of political and social crises in the country.

Materials & Methods
This article is methodologically qualitative, analytical, and applied-developmental, and by utilizing library resources and the theory of historical institutionalism, it examines the function of social policy in the governments of the Islamic Republic of Iran. The reason for choosing this theoretical approach is that it provides a more comprehensive perspective on the structural characteristics of social policy and government policy in this process, and by utilizing institutions, it studies and examines the sequences of social, political and economic behavior and their changes over time.

Discussion & Result
The development and expansion of modern social policy in Iran dates back to the Pahlavi era, but the existence of a hierarchical government structure, the government monopoly on economic resources, etc. during this period did not allow for the desired implementation of social policy. In general, although during the Islamic Revolution and in criticism of the Pahlavi regime's performance in the social sphere, the establishment of social justice was emphasized by the revolutionaries and society, in the first decade of the establishment of the Islamic Republic system, due to the heavy political atmosphere and the chaos of the country's conditions, no modern social policy was accepted and therefore, social problems were added. With the emergence of the construction and reform governments and their emphasis on the market economy instead of the cooperative economy, public expectations for meeting the need for social justice increased, but the severe spread of inflation and financial pressures on the middle and lower classes doubled the need for social justice, so that the principled government based its main goals and slogans on these needs, but it was not successful in meeting them. In the moderate government, many areas of social policy were included in the main tasks of government agencies, but nevertheless, social policy was and is still one of the unresolved issues of Iranian society. Therefore, it is clear that such ineffective social policy could not help strengthen the relationship between the state and the people and, as a result, caused protests and political and social crises in the period under study. In general, the roots of the ineffectiveness of social policy during the Islamic Republic of Iran can be found in the following factors: the rentier nature of the state; the domination of the political over the social; the idealism of the policy system; the lack of consensus among political elites; the irresponsibility of the state and policymakers; problems in the area of ​​policy implementation; the lack of attention to the issue of citizenship; the gap between the area of ​​social policy and the theoretical area; and the lack of attention to global developments (the globalization process). However, with all this, it is possible to adopt strategies that will make social policy more efficient and as a result, strengthen the relationship between the state and the people in Iran, and prevent political and social crises. These strategies include: reducing the stste reliance on rentier revenues; avoiding politicization in the decision-making process; basing the policy system on facts; creating consensus among political elites; holding the state and policymakers accountable; resolving problems in the area of ​​policy implementation; paying attention to citizenship rights; creating a strategic headquarters to logically confront challenges; creating a link between the social policy and theoretical spheres; and adopting a logical approach to global developments (the globalization process).

Conclusion
During the Islamic Republic, despite the revolutionaries’ emphasis on formulating a comprehensive social policy and eliminating social injustice and inequalities, we witness the ineffectiveness of social policy and the governments’ lack of serious attention to this area of ​​policy. In general, although some measures were taken in the area of ​​social policy in the governments of the Islamic Republic, they were insufficient and did not bear significant fruit, so that we are still faced with the issue of social injustice in Iran, and this issue, in general, had a negative impact on the trust and attitude of a significant part of the Iranian people towards the political system and caused political and social crises in this period. From the perspective of this article, factors such as the rentier nature of the state, the domination of the political over the social, the idealism of the policy system, etc., have played an effective role in the ineffectiveness of social policy in the period under discussion. However, despite all this, the article believes that the Islamic Republic system can by eliminating and correcting the above factors and adopting appropriate and logical strategies, make social policy more efficient and strengthen people's trust in the state.
