Abdo′men, in man, the belly, or lower cavity of the trunk, separated from the upper cavity or thorax by the diaphragm or midriff, and bounded below by the bones of the pelvis. It contains the viscera belonging to the digestive and urinary systems.

The name is given to the corresponding portion of the body in other animals. In insects it comprises the whole body behind the thorax, usually consisting of a series of rings. See Alimentary Canal.

Ab′dul-Az′iz, Sultan of Turkey, was born in Feb., 1830, and succeeded his brother Abdul-Mejid, in June, 1861. He concluded treaties of commerce with France and England, both of which countries he visited in 1867. Deposed in May, 1876, he committed suicide, or more probably was assassinated, in June of the same year. He was succeeded by his son Murad V. See next article.

Ab′dul-Ham′id, Sultan of Turkey, younger son of Abdul-Mejid, born 22nd Sept., 1842, succeeded his brother Murad V, who was deposed on proof of his insanity in 1876. At that time Turkey, which was at war with Serbia, was compelled to agree to an armistice at the demand of Russia. The persecution and oppression of the Christian population of Bulgaria had roused remonstrances from other European countries, and a congress met at Constantinople to consider a constitution which the Porte had proclaimed. The conference was a failure, and in April, 1877, war was declared by Russia. During the sanguinary struggle which ensued the Turks fought with great bravery, but they had ultimately to sue for peace. A treaty was signed at San Stefano in Feb., 1878, but its provisions were modified by a congress of the Great Powers which met at Berlin. The island of Cyprus was ceded to Britain. Serbia, Rumania, and Montenegro were freed from Turkish suzerainty altogether; Bulgaria was left in nominal dependence; whilst Bosnia and Herzegovina were placed under Austrian administration. In 1881 Thessaly was transferred to Greece; in 1885 E. Roumelia became united to Bulgaria. Ever since the treaty of Berlin, Abdul Hamid saw in Germany the future friend of Turkey. He therefore entrusted Germans with the reorganization of his army and finances. Subsequently there were massacres of Christians, a war with Greece (1897), and troubles in Crete and Macedonia. In April, 1909, the Sultan was deposed, and his brother, Rashid Effendi, proclaimed sultan as Mohammed V. Abdul Hamid died in captivity 10th Feb., 1918.

Abd-ul-Lat′if, an Arab writer and physician, was born at Bagdad in 1161 and died there in 1231. He was patronized by the celebrated Saladin, and published an excellent description of Egypt, which is still extant. It was translated into English by White, Oxford, 1800.

Ab′dul-Mej′id Khan, Sultan of Turkey, born in 1823, succeeded his father, Mahmud II,

1st July, 1839. At the time of his accession Mehemet, Pasha of Egypt, had risen a second time against the Turkish yoke; his son Ibrahim had inflicted a severe defeat on the Turks at Nizib (24th June, 1839), and was advancing on Constantinople. But the intervention of the leading European Powers checked the designs of Mehemet Ali, and saved the Turkish empire. Abdul-Mejid was desirous of carrying out reforms, but most of them were not enforced, or caused bloody insurrections where attempts were made to carry them out. Owing to disputes between the Latin and Greek Churches regarding the rights of precedence and possession of the 'holy places' in Palestine, and to demands made by the Tsar virtually implying the right of protectorate over the Christian subjects of the Sultan, war broke out between Turkey and Russia in 1853. In the following year the Porte effected an alliance with France and England (hence the Crimean War), and later on with Sardinia. (See Crimean War.) Abdul-Mejid died 25th June, 1861, and was succeeded by his brother, Abdul-Aziz.

Abeceda′rian, a term formed from the first four letters of the alphabet, and applied to the followers of Storch, a German Anabaptist (1522), because they rejected all worldly knowledge, even the learning of the alphabet.
