ديوان (Council) refers to a governing body or assembly that provides advice and support to a leader or ruler. It often consists of a group of advisors or officials who help in decision-making processes, particularly in matters of governance, law, and administration. The term is commonly used in various cultures, especially in the context of Islamic governance. In historical contexts, the ديوان played a crucial role in the administration of empires, such as the Ottoman Empire and Persian Empire. These councils were responsible for managing state affairs, including finance, military, and public welfare, ensuring that the ruler's policies were effectively implemented.
