Austria, Empire of

(Ger. Oesterreich , “eastern kingdom”). One of the most extensive and most populous of European kingdoms, comprising the southeast part of Central Europe and more than half the territory of the Danube. It is composed of a union of different states, some of them at one time forming independent kingdoms, inhabited by races of people differing from each other in descent, language, customs, laws, and religion, held together as one empire by being united under one sovereign and one central government. This territory, which was comprised in Noricum and part of Pannonia, was annexed to the Roman empire in 33, was overrun by Huns, Avars, etc., in the 5th and 6th centuries, and taken from them by Charlemagne, who united it to Germany as the “eastern kingdom,” 791-96. In 1156 the country was made a hereditary duchy by the emperor Frederick I., and in 1453 was raised to an archduchy. Rodolph, count of Hapsburg, elected emperor of Germany in 1273, acquired Austria in 1278, and from 1493 to 1804 his descendants were emperors of Germany. On August 11, 1804, Francis II. became hereditary emperor of Austria. Vienna, the capital, was entered by a French army November 14, 1805, and evacuated January 12, 1806, Austria losing Venice and the Tyrol by the treaty of Presburg. Francis renounced the title of emperor of Germany August 6, 1806. Vienna was again taken by the French May 13, 1809, but was restored at the peace, October 14 following. In 1848 Lombardy revolted, and Milan and other disaffected towns formed an alliance with Charles Albert, king of Sardinia, who then invaded the Austrian territory at the head of a large army, victory seeming for a time to favor the Italians. In the following year, however, both the insurgents and their Sard in i an ally were repeatedly defeated by the Austrian forces under Marshal Radetzky, and Lombardy was again brought under the Austrian sway, but was ceded to Sardinia in 1859. Pru ia and Italy declared war against Austria in 1866; but, through the intervention of Napoleon, peace was concluded the same year, Austria losing Venice and the Quadrilateral.
