Ibrahim Bey (1735 – 1816/1817) was a Mamluk chieftain and regent of Egypt.
While the Georgian historian Alexander Mikaberidze claims that Ibrahim Bey was born as Abram Sinjikashvili (აბრამ სინჯიკაშვილი) into the family of a Christian priest in Martqopi in the southeastern Georgian province of Kakheti; some 19th-century and early 20th-century sources identified him as Circassian. As a child, he was captured by Ottoman slave raiders and sold out in Egypt where he was converted to Islam and trained as a Mamluk. Through loyal service to the Circassian Muhammad Bey Abu al-Dhahab, the Mamluk ruler of Egypt, he rose in rank and attained to the dignity of bey.
With time he emerged as one of the most influential Mamluk commanders, sharing a de facto control of Egypt with his fellow Murad Bey. The two men became a duumvirate, Murad Bey managing military matters while Ibrahim Bey managed civil administration. They survived through the persistent Ottoman attempts at overthrowing the Mamluk regime and civil strifes. They served as kaymakams (acting governors) in Egypt on occasion, although they effectively held de facto power for decades, even over the appointed Ottoman governor of Egypt. From 1771 to 1773, Ibrahim Bey served as the amir al-hajj (commander of the hajj caravan) of Egypt.
In 1786, the Ottoman sultan Abdülhamid I sent Kapudan Pasha (grand admiral of the Ottoman Navy) and Cezayirli Gazi Hasan Pasha to drive out Ibrahim and Murad Bey. Hasan Pasha was fervent and thorough in his efforts and succeeded in the short term, reestablishing direct Ottoman Empire control over Egypt.Ismail Bey was appointed as new Mamluk leader and Shaykh al-Balad (civil governor and de facto ruler). However, in 1792, only six years after their expulsion by Hasan Pasha, the duumvirate returned to Cairo from hiding in southern Egypt and took back de facto control.
