The title Mullah (Arabic: ملا) used by the family was used to show respect to educated Muslim leaders of the clergy.[1][2] The rulers of Muslim India used the institution of the Qadi (Arabic: قاضي), who was given the responsibility for total administrative, judicial and fiscal control over a territory or a town. He would maintain all the civil records as well.
He would also retain a small army or force to ensure that his rulings are enforced. In most cases, the kazi (qadi) would pass on the title and position to his son, descendant or a very close relative. Over the centuries, this profession became a title within the families, and the power remained within one family in a region. Throughout South Asia, various such families are found who descended through their ancestors and retained the lands and position. Each family is known by the town or city that their ancestors controlled.[3]
