when did the ottoman empire lose control of palestine
History of Palestine In October 1831, Muhammad Ali of Egypt dispatched his modernized army commanded by his son Ibrahim Pasha in a campaign to annex Ottoman Syria, including Palestine. Ibrahim Pasha's forces had previously defeated the Ottomans and gained control of Sudan and the western Arabian Peninsula. Their entry into Palestine was not resisted by the local inhabitants,[260] nor by the rural sheikhs of the central highlands.[261] However, Abdullah Pasha resisted the conquest from Acre, which was besieged and ultimately surrendered in May 1832.[262]
Caliphate The caliphate was claimed by the sultans of the Ottoman Empire beginning with Murad I (reigned 1362 to 1389),[47] while recognising no authority on the part of the Abbasid caliphs of the Mamluk-ruled Cairo. Hence the seat of the caliphate moved to the Ottoman capital of Edirne. In 1453, after Mehmed the Conqueror's conquest of Constantinople, the seat of the Ottomans moved to Constantinople, present-day Istanbul. In 1517, the Ottoman sultan Selim I defeated and annexed the Mamluk Sultanate of Cairo into his empire.[13][12] Through conquering and unifying Muslim lands, Selim I became the defender of the Holy Cities of Mecca and Medina, which further strengthened the Ottoman claim to the caliphate in the Muslim world. Ottomans gradually came to be viewed as the de facto leaders and representatives of the Islamic world. However, the earlier Ottoman caliphs did not officially bear the title of caliph in their documents of state, inscriptions, or coinage.[12] It was only in the late eighteenth century that the claim to the caliphate was discovered by the sultans to have a practical use, since it allowed them to counter Russian claims to protect Ottoman Christians with their own claim to protect Muslims under Russian rule.[48][49]
