Abbas Pasha, viceroy of Egypt, grandson of Mehemet Ali, and nephew of Ibrahim Pasha, born in 1813, died July 12, 1854. He took an active part in the Syrian wars of his grandfather, but without distinguishing himself. After the brief reign of Ibrahim Pasha, Mehemet Ali's eldest son, Abbas ascended the viceregal throne, as hereditary successor, in 1848. He undid in many respects the work of Mehemet Ali, dismissed his European officials, and manifested an arbitrary, capricious, and cruel disposition. He succeeded, however, in disarming his adversaries at Constantinople, who endeavored to cripple him and reduce Egypt to a more inferior condition. In the Crimean war he aided the sultan. His death was sudden, and probably violent.
