The 1864 “VIlayet Law” (Turkish: Teskil-i Vilayet Nizamnamesi, translated to “Statute for Formation of Province”) was introduced during the Tanzimat era of the Ottoman Empire administration. This era of administration was marked by reform movements, with provincial movements led largely by Midhat Pasa, a key player in the Vilayet Law itself. The Vilayet Law reorganized the provinces within the empire, replacing the eyalet system.
