Alexander II, Emperor of Russia, was born 29th April, 1818, and succeeded his father Nicholas in 1855, before the end of the Crimean war. After peace was concluded, the new emperor set about effecting reforms in the empire, the greatest of all being the emancipation of the serfs in 1861, a measure which gave freedom, on certain conditions, to 50,000,000 of human beings who were previously in a state little removed from that of slavery. Under him, too, representative assemblies in the provinces were introduced, and he also did much to improve education, and to reorganize the judicial system. During his reign the Russian dominions in Central Asia were extended, a piece of territory south of the Caucasus, formerly belonging to Turkey, was acquired, and a part of Bessarabia restored to Russia. The latter additions resulted from the Russo-Turkish war of 1877-8. He was killed by an explosive missile flung at him by a Nihilist in a street in St. Petersburg (now Petrograd), 13th March, 1881. He was succeeded by his son, Alexander III. His only daughter was married to the Duke of Edinburgh.

Alexander III, Emperor of Russia, son of Alexander II, born in 1845, became heir to the throne on the death of his eldest brother, Nicholas (1865). In 1863 he married Princess Dagmar of Denmark; he succeeded to the throne in 1881, on the assassination of his father, being crowned in Moscow in 1883. He gave up the reforms begun by his father, and ruled in the old autocratic fashion, restricting the liberties of Finland and the Baltic Provinces, and encouraging persecution of the Jews. He spent much time in the closely-guarded castle of Gatchina, to be safe from Nihilistic attempts, several of which he narrowly escaped. He endeavoured to put down corruption and underhand dealing among the bureaucracy, and in his own habits gave an example of simplicity and economy. While showing himself suspicious of Germany and Austria-Hungary, he entered on friendly relations with France. He began to suffer from disease of the kidneys in 1893, and died at Livadia on 1st Nov., 1894. He was succeeded by his eldest son, Nicholas II.

Alexander I, King of Serbia, born in 1876. He was the son of King Milan, and on the abdication of his father in 1889 was proclaimed king under a regency. He married Madame Draga Mashin, a widow, who was much older than himself. Both were assassinated on 11th June, 1903.

Alexander, Boyd, British explorer and naturalist, born in 1873. He led many expeditions for research and exploration to the Cape Verde Islands, the Zambesi River, and various parts of the world. He also discovered many new birds when he ascended the Mount St. Isabel. In 1908 he received the gold medal of the Royal Geographical Society. He was murdered by natives in May, 1910, while exploring the French Congo. He wrote From the Niger to the Nile (1907), &c. Boyd Alexander's Last Journey was published in 1912.

Alexander Nevskoi, a Russian hero and saint, son of the Grand-Duke Jaroslav, born in 1219, died in 1263. He fought valiantly against assaults of the Mongols, the Danes, Swedes, and Knights of the Teutonic Order. He gained the name of Nevskoi in 1240, for a splendid victory, on the Neva, over the Swedes. The gratitude of his countrymen commemorated the hero in popular songs, and raised him to the dignity of a saint. Peter the Great built a splendid monastery at St. Petersburg (Petrograd) in his honour, and in memory of him established the Order of Alexander Nevskoi.

Alexander Seve′rus, a Roman emperor, born in 208, died A.D. 235. He was raised to the imperial dignity in A.D. 222 by the prætorian guards, after they had put his cousin the Emperor Heliogabalus to death. He governed ably both in peace and war; and also occupied himself in poetry, philosophy, and literature. He was very tolerant in religious matters, and although not professing Christianity intended to erect a temple to Christ, but was prevented by the pagan priests from carrying out this plan. In 232 he defeated the Persians under Artaxerxes, who wished to drive the Romans from Asia. When on an expedition into Gaul, to repress an incursion of the Germans, he was murdered with his mother in an insurrection of his troops, headed by the brutal Maximin, who succeeded him as emperor.

Alexanders (Smyrnium Olusātrum), an umbelliferous biennial plant, a native of the Mediterranean region, but found in Great Britain and Ireland. It was formerly cultivated for its leaf-stalks, which, having a pleasant aromatic flavour, were blanched and used instead of celery—a vegetable that has taken its place.

Alexandra, the queen mother, widow of Edward VII, daughter of Christian IX, King of Denmark, was born at Copenhagen on 1st Dec., 1844, and was married on 10th March, 1863, being Princess of Wales up to the death of Queen Victoria and the accession of King Edward in Jan., 1901. She was highly popular from the first in the country of her husband, as she constantly showed an interest in all

benevolent causes. She has been the mother of six children, one of whom died in infancy, while the eldest, Edward, Duke of Clarence and Avondale, died in 1892 at the age of twenty-eight. Cf. S. A. Tooley, Queen Alexandra.
