Edict of Gülhane

The Gülhane Hatt-ı Şerif ("Supreme Edict of the Rosehouse"; French: Hatti-Chérif de Gulhané) or Tanzimât Fermânı ("Imperial Edict of Reorganization") was a proclamation by Ottoman Sultan Abdülmecid I in 1839 that launched the Tanzimât period of reforms and reorganization in the Ottoman Empire. The 125th anniversary of the edict was depicted on a former Turkish postcard stamp.

The proclamation was issued at the behest of reformist Grand Vizier Mustafa Reşid Pasha. It promised reforms such as the abolition of tax farming, reform of conscription, and guarantee of rights to all Ottoman citizens regardless of religion or ethnic group. The goal of the decree was to help modernize the empire militarily and socially so that it could compete with the Great Powers of Europe. It also was hoped the reforms would win over the disaffected parts of the empire, especially in the Ottoman controlled parts of Europe, which were largely Christian. At the time of the edict, millets (independent communal law-courts) had gained a large amount of religious autonomy within the empire, threatening the central government. This edict, along with the subsequent Imperial Reform Edict of 1856, was therefore an early step towards the empire's goal of Ottomanism, or a unified national and legal Ottoman identity. It was published in the Tekvim-i Vekayi in Ottoman Turkish. In addition, it was published in Greek and French, the latter in Moniteur ottoman, and François Alphonse Belin, a dragoman, created his own French version, published in the Journal Asiatique.

The Edict of Gülhane did not enact any official legal changes but merely made royal promises to the empire's subjects, and they were never fully implemented due to Christian nationalism and resentment among Muslim populations in these areas. At the end of the Crimean War, the Western powers pressured Turkey to undertake further reforms, mainly to deprive the Russians, with whom peace negotiations were then under way, of any further pretense for intervention in the internal affairs of the Ottoman Empire. The result of these pressures was the proclamation of the Hatt-ı Hümâyûn (Imperial Rescript) of 18 February 1856.
