The Ministry of Justice (Ottoman Turkish: عدليه نظارتی; Turkish: Adliyye Nezâreti) was the justice ministry of the Ottoman Empire, based in Constantinople (now Istanbul). It also served as the Ministry of Religions.
It was established in 1879 as part of a reorganisation of the empire's legal system. Non-Muslim ecclesiastical authorities relied on the ministry. The ministry took control of the commercial courts and commercial appeal courts from the Ministry of Commerce.
Beginning in the latter half of the 19th century, the Nizamiye Courts (also written Nizami) were a secular court system introduced within the Ottoman Empire during the Tanzimat era. This court system was administered under the Ottoman Ministry of Justice. Although secular, the Mecelle (the Ottoman version of codified Sharia) was eventually applied to the courts. This court system drew much influence from French models at the time. These courts enabled the further growth of legal pluralism within Ottoman jurisprudence.
