The grand vizier of the Ottoman Empire ( or Sadr-ı Azam (Sadrazam); Ottoman Turkish: or ) was the de facto prime minister of the sultan, with the absolute power of attorney and, in principle, removable only by the sultan himself in the classical period, before the Tanzimat reforms, or until the 1908 Revolution. He held the imperial seal and could summon all other viziers to attend to affairs of the state in the Imperial Council; the viziers in conference were called "kubbe viziers" in reference to their meeting place, the Kubbealtı ('under-the-dome') in Topkapı Palace. His offices were located at the Sublime Porte.

History

During the emerging phases of the Ottoman state, "vizier" was the only title used. The first of these Ottoman viziers who was titled "grand vizier" was Çandarlı Kara Halil Hayreddin Pasha (also known as Çandarlı Halil Pasha the Elder). The purpose in instituting the title "grand vizier" was to differentiate the holder of the sultan's seal from other viziers. The initially more regularly used title of vezir-i âzam was slowly replaced by sadrazam, both meaning grand vizier in practice. Throughout Ottoman history, the grand viziers have also been called sadr-ı âlî ('high vizier'), vekil-i mutlak ('absolute attorney'), sâhib-i devlet ('holder of the state'), serdar-ı ekrem ('gracious general'), serdar-ı azam ('grand general'), and zât-ı âsafî ('vizieral person') and başnazır, literally "prime minister" in Ottoman Turkish. The Office of the Grand Vizier was called the sadaret.

In the late periods of the Ottoman Empire, especially during and after the 19th century, the grand vizier began to hold a position almost identical to that of a prime minister in other European states. Reforms seen during and after the Tanzimat (1838), the First Constitutional Era (1876–1878), and the Second Constitutional Era (1908–1920) further brought the office of the grand vizier in line with the European standard, making the incumbent the head of a Cabinet of other ministers. During the two constitutional eras, the grand vizier also served as the speaker of the Senate, the upper house of the bicameral Ottoman Parliament. With the establishment of the Republic of Turkey in 1923, the Prime Minister of Turkey took on the roles of the former office.

Grand viziers were often replaced or resigned in rapid succession, frequently leading to political instability. In the final 10 years of the Empire alone, the office of the grand vizier changed hands 13 times between 12 men; some, such as Ahmed Izzet Pasha and Salih Hulusi Pasha, held office for less than a month.

Office of the Grand Vizierate The Office of the Grand Vizierate was known as the Sadaret-i Uzma, or alternatively the Baş Vekâlet (The Prime Ministry), or Bâb-ı Âli (Literally the Sublime Porte, all the departments under the Vezierate). In 1839, this office included only included the Âmedi-i Divan-ı Hümayun (Office of the Imperial Council).

List of grand viziers Chief viziers (1320–1439) In the early Ottoman beylik, the vizier acted as the sultan’s chief deputy for administration and military affairs. The position began with Alaeddin Pasha (c. 1320–1331) and was later dominated by the Çandarlı family, who helped build the empire’s administrative foundations. +VizierTerm of officeSultan Portrait Name Took office Left office Time in officeKemaleddinoğlu Alaeddin Pasha1320133111 yearsOsman IOrhanMahmudoğlu Nizamüddin Ahmed Pasha1331134817 yearsMehmet Hacı Pasha134813491 yearSinanüddin Fakih Yusuf Pasha13491364 †15 yearsMurad IÇandarlızade Halil Hayreddin Pasha13641387 †Çandarlızade Ali Pasha13871406 †19 yearsBayezid ISüleyman ÇelebiImamzade Halil Pasha140614137 yearsMehmed IBayezid Pasha14131421 †8 yearsMurad IIÇandarlızade Ibrahim Pasha the Elder14211429 †8 years Mehmed Nizamüddin Pasha1429143910 years

Grand Viziers (1439–1839) The position of grand vizier was established with Murad II's appointment of Çandarlızade Halil Pasha the Younger to such a position. In the 19th century, Mahmud II would abolish the title of Grand Vizier, and appointed Mehmed Emin Rauf Pasha as Başvekil, or Prime Minister. Upon Sultan Abdülmecid I's ascention to the throne, the Grand Vizierate was restored. +Grand VizierTerm of officeSultanPortraitNameTook officeLeft officeTime in officeÇandarlızade Halil Pasha the

Hamidian viziers (1878–1908) Abdul Hamid II suspended the constitution and parliament in the aftermath of the 1877–1878 Russo Turkish war, and ruled the Ottoman Empire for the next three decades in a personal dictatorship. Opposition politicians dubbed this era of Ottoman history as the era of İstibdat (despotism). Abdul Hamid revived the use of the title Başnazır, or Prime Minister, though he eventually settled on his government chiefs being called Sadr-ı Azam, or Grand Vizier.
