However, after there were troubles between the Turkish grand vizier Çandarlı Halil Pasha the Younger and Sultan Mehmed II (who had him executed), there was a rise of slave administrators (devshirme).
The initially more frequently used title of vezir-ı a’zam (وزیر اعظم) was gradually replaced by another one,[citation needed] sadr-ı a’zam (صدر اعظم from Arabic صَدْر "front part, bosom, forehead, lead, forefront" and أعْظَم "superior, major, maximal, paramount, grand", informally pronounced sadrazam),[3] both meaning "grand vizier" in practice.
In the Ottoman Empire, executing a Grand Vizier of Turkish origin (in the event they were rebellious) and an enslaved foreigner would also give rise to different reactions.
He consolidated power within the position and sent the Sultan away from the city on hunting trips, thus stopping Mehmed's direct management over the state.
On his deathbed five years later, he convinced Mehmed to appoint his son (Köprülü Fazıl Ahmed Pasha) as the next Grand Vizier, thus securing his dynasty a position of supreme power in the Empire.
[8] In Ottoman legal theory, the Sultan was supposed to conduct affairs of state exclusively via the Grand Vizier, but in reality, this arrangement was often circumvented.
[9] After the Tanzimat period of the Ottoman Empire in the 19th century, the Grand Viziers came to assume a role more like that of the prime ministers of contemporary Western monarchies.
[10] Bairam Khan was the Grand Vizier of the Mughal Empire, who led the forces of Akbar to victory during the Second Battle of Panipat.
In 1718, Balaji Vishwanath, leader of the antagonistic Maratha Confederacy, secured the right to collect Chauth and Sardeshmukhi from the Subahs of the Mughal Empire by the rogue Vizier Syed Hassan Ali Khan Barha, whose grip over the Deccan had substantially weakened.
[12] Asaf Jah I, however, refused to grant Chauth to the Maratha Confederacy during its onset in 1718 and in 1721, after the nobility of the Mughal Empire had the two Sayyid Brothers assassinated.
He successfully repelled Baji Rao I during the Battle of Delhi (1737), and negotiated peace after the occupation of the Mughal Empire by the forces of Nader Shah.
After defeating Ahmad Shah Durrani, the new Mughal emperor, Ahmad Shah Bahadur, posted Safdarjung, Nawab of Oudh as Mughal Grand Vizier, Feroze Jung III as Mir Bakshi and Muin ul-Mulk (Mir Mannu), the son of late Grand Vizier Qamaruddin Khan, as the governor of Punjab.
