Niš Eyalet (Ottoman Turkish: ایالت نیش; Eyālet-i Nīş)[2] was an administrative territorial entity of the Ottoman Empire located in the territory of present-day southern Serbia and western Bulgaria.

He was a reformer influenced by Western ideas and the eyalet became a showpiece of the reformist movement.

He tackled the problems of communications and security: he set up a system of block-houses to stop the incursion of armed bands from Serbia.

According to his laudatory son's biography of him, "he organized a gendarmerie, secured the peaceful collection of taxes, and put an end to all religious persecution."

In the next three years, he carried through a large program of school-building and other public works, as well as introducing a provincial newspaper.
