Sultan of Turkey; crushed a rebellion on his accession by putting his brother to death, on whose behalf the janissaries had risen, as they afterwards did to their annihilation at his hands by wholesale massacre; by the victory of Navarino in 1827 he lost his hold of Greece, which declared its independence, and was near losing his suzerainty in Egypt when he died; his reign was an eventful one (1785-1839).
