The Old Turkish Aristocracy was a class of wealthy and powerful individuals who held positions of authority in the Ottoman Empire. The term 'Aghas' is used to refer to members of this class, and it is derived from the Persian word for 'MASTER'. Aghas were typically appointed by the Sultan and held a variety of roles, including military commanders, governors, and tax collectors. They were also responsible for maintaining order in their respective regions and ensuring that the Sultan's laws were followed.
