In the late 18th century, the Ottoman Empire faced threats on numerous frontiers from multiple industrialised European powers. In response, the empire initiated a period of internal reform, attempting to bring itself into competition with the expanding West. The period of these reforms is known as the Tanzimat, and led to the end of the Old Regime period. Despite the Ottoman empire's precarious international position, the central state was significantly strengthened. The process of reforming and modernization in the empire began with the declaration of the Nizam-I Cedid during the reign of Sultan Selim III and was punctuated by several reform decrees, such as the Hatt-ı Şerif of Gülhane in 1839 and the Hatt-ı Hümayun in 1856. Over the course of the 19th century, the Ottoman state became increasingly powerful and rationalized, exercising a greater degree of influence over its population than in any previous era.

The Tanzimat was a period of reform in the Ottoman Empire that began with the Gülhane Hatt-ı Şerif in 1839 and ended with the First Constitutional Era in 1876. The Tanzimat era began with the purpose not of radical transformation, but of modernization, desiring to consolidate the social and political foundations of the Ottoman Empire. It was characterised by various attempts to modernise the Ottoman Empire and to secure its territorial integrity against internal nationalist movements and external aggressive powers. The reforms encouraged Ottomanism among the diverse ethnic groups of the Empire and attempted to stem the rise of nationalism in the Ottoman Empire.
