Hatti-Sherif , (Turkish, noble writing), any ordinance written by the sultan's hand, or which contains his paraf, or flourish, and the words, " Let this my order be obeyed." Sometimes it is called hatti-humayum, "august writing." A hatti-sherif is irrevocable. The most celebrated in modern times was the hatti-sherif of Gulhane, promulgated by the sultan Ab-dul-Medjid, Nov. 3,1839, guaranteeing life and property to all subjects of the empire without distinction of creeds. This ordinance was confirmed by the hatti-humayum of Feb. 18, 1850, which granted religious liberty to the non-Mohammedan population, abolished the civil and judicial authority of the Mussulman ecclesiastics, proclaimed the equality of all creeds and nationalities, abolished persecution and the punishment of religious converts, made non-Mohammedans admissible to public office and ordained their representation in the council of state, permitted foreigners to hold landed property, decreed the establishment of public schools, the codification of the laws, the reform of the monetary system and of the police, and proposed to introduce other public improvements.
