Abstract
About nine months before his passing, Imam Khomeini (pbuh) proposed Ayatollah Khamenei as the future leader of the Islamic Revolution, and subsequently, during various periods, he explained the necessary characteristics for leadership of an Islamic society. Considering that the system of religious democracy is a unique and unprecedented model of governance, and one of the reasons for this distinction is the existence of the leadership position, it is necessary to examine whether the system's performance in the selection of the leader has been in line with the indicators of religious democracy (Islamism and republicanism). Therefore, the main question of this research is: What indicators led to the selection of Ayatollah Khamenei as the leader of the Islamic Republic of Iran? Given the topic and research question, it seems that a qualitative method with an analytical-descriptive approach is an appropriate method to achieve the research results. The reason for choosing this method is that it allows for the description of events related to the selection of the leader, while examining the realization of indicators related to the processes of republicanism and elements of Islamism in the thought of religious democracy, with the processes that have taken place for the selection of the leader and the characteristics of the selected individual. The results shows that the specific indicators of religious democracy (republicanism and Islamism) based on legitimacy in Shia political thought, the system of Imamate, and popular presence and acceptance, which are reflected in the constitution, govern the process of the selection of Ayatollah Khamenei.

Introduction
After the victory of the Islamic Revolution in Iran in 1979, a unique form of government based on "religious democracy" was established, which recognized the sovereignty of Islam and the people's sovereignty over their political and social destiny. The system of religious democracy is a unique and unprecedented model of governance, and one of the reasons for this distinction is the existence of the leadership position. Therefore, it is necessary to examine whether the system's performance has been in line with the indicators of religious democracy (Islamism and republicanism) in the selection of the leader.

Materials and Methods
The research question is: What indicators led to the selection of Ayatollah Khamenei as the leader of the Islamic Republic of Iran? The hypothesis is that the indicators of religious democracy (Islamism and republicanism) based on legitimacy in Shia political thought, the system of Imamate, and popular presence and acceptance, which are reflected in the constitution, govern the processes of selecting the leader.
The research method is qualitative with an analytical-descriptive approach. The reason for choosing this method is that it allows for the description of events related to the selection of the leader, while examining the realization of indicators related to the processes of republicanism and elements of Islamism in the thought of religious democracy, with the processes that have taken place for the selection of the leader and the characteristics of the selected individual.

Discussion & Result
The selection of Ayatollah Khamenei as the leader of the Islamic Republic of Iran is a significant event in the history of the country, and it is essential to examine the indicators of religious democracy (Islamism and republicanism) that led to his selection. This section will provide a comprehensive and in-depth analysis of the topic, building upon the existing content, and will discuss the various aspects of the selection process.

Indicators of Islamism
The indicators of Islamism in the selection of Ayatollah Khamenei as the leader of the Islamic Republic of Iran are numerous. Firstly, Imam Khomeini's approval and description of Ayatollah Khamenei as a Mujtahid. Imam Khomeini's endorsement of Ayatollah Khamenei is a testament to his expertise in Islamic sharia and his ability to lead the country in accordance with Islamic principles.
Secondly, Ayatollah Khamenei's jurisprudence and expertise in Islamic sharia are also indicators of Islamism. His extensive knowledge of Islamic sharia and his ability to interpret and apply it in a way that is consistent with the principles of the Islamic Republic are essential qualities for a leader of the country.
Thirdly, Ayatollah Khamenei's courage and insight in the face of challenges are also indicators of Islamism. His ability to navigate the complex political landscape of Iran and to make difficult decisions in the face of opposition and adversity is a testament to his strength and resilience as a leader.
Finally, Ayatollah Khamenei's management and leadership abilities are also indicators of Islamism. His ability to manage the country's affairs and to lead the government in a way that is consistent with Islamic principles is essential for the success of the Islamic Republic.

Indicators of Republicanism
The indicators of republicanism in the selection of Ayatollah Khamenei as the leader of the Islamic Republic of Iran are also numerous. Firstly, the formation of the Assembly of Experts for the selection of the leader is a significant indicator of republicanism. The Assembly of Experts is a democratic institution that is responsible for selecting the leader of the country, and its formation is a testament to the democratic nature of the Islamic Republic.
Secondly, the presentation of proposals by the members of the Assembly is also an indicator of republicanism. The members of the Assembly are elected by the people, and their proposals reflect the will of the people. The presentation of proposals by the members of the Assembly is a democratic process that allows for the participation of the people in the selection of the leader.
Thirdly, the selection of the leader based on the constitution is also an indicator of republicanism. The constitution of the Islamic Republic of Iran outlines the qualifications and characteristics that a leader must possess, and the selection of Ayatollah Khamenei was based on these criteria. The selection of the leader based on the constitution is a democratic process that ensures that the leader is accountable to the people and is committed to upholding the principles of the Islamic Republic.
Finally, the widespread popular acceptance and allegiance to the leader are also indicators of republicanism. The people of Iran have consistently demonstrated their support for Ayatollah Khamenei, and his leadership has been widely accepted by the people. The widespread popular acceptance and allegiance to the leader are a testament to the democratic nature of the Islamic Republic and the legitimacy of Ayatollah Khamenei's leadership.

Conclusion
The paper concludes that the indicators of religious democracy (Islamism and republicanism) have been realized in the selection of Ayatollah Khamenei as the leader of the Islamic Republic of Iran. The selection of Ayatollah Khamenei was based on the approval and description of Imam Khomeini, his jurisprudence and expertise in Islamic law, his courage and insight in the face of challenges, and his management and leadership abilities. The formation of the Assembly of Experts, the presentation of proposals by the members, and the selection of the leader based on the constitution are also indicators of republicanism. The widespread popular acceptance and allegiance to the leader, as well as the review of the leader's qualifications and characteristics in accordance with the new constitution, are also indicators of the realization of religious democracy in the selection of the leader.
