the capital of Servia. It is situated on the Danube, midway between Vienna and the Black Sea . It occupies a position strongly fortified by nature. The citadel is built on a lofty promontory and is a sort of Gibraltar, commanding the pass through which travel up or down the river must go. For that reason it is the key to the upper Danube. Originally garrisoned by a Roman legion, it has been fortified, stormed, surrendered, and ceded a score of times. Greeks, Turks, Austrians, and Hungarians have fought desperately for its possession. One of the most memorable sieges was conducted by Prince Eugene in 1717, when he took the citadel after he had defeated an army of 200,000 Turks "under the walls of high Belgrade." Since 1878 it has been the capital of an independent state. Its position has made it the center of communication between the Upper Danube and the Black Sea region. Lines of steamers ply in both directions. The main railway of the Danube Valley passes through Belgrade on the way to Constantinople. The population in 1902 was reported at 69,097. The city has a large wholesale and shipping business. The exports are chiefly grain, fruits, especially fresh plums, marmalade, meats, and live stock. Street railways, telephones, electric lights, waterworks, new public buildings, and fine shops give the city quite a modern appearance. See Servia 2026 Editor's Note: Belgrade is now the capital of Serbia — "Servia" has vanished from the map — and it remained the fought-over prize this entry describes: occupied in both world wars, capital of Yugoslavia, and bombed by NATO in 1999 during the Kosovo conflict. It is reckoned one of the most besieged cities in history. (Ed: BR 2026-06-07)
Collier's New Encyclopedia (1921)
a city and capital of Serbia, on the right bank of the Danube in the angle formed by the junction of the Save with that river, consists of the citadel or upper town, on a rock 100 feet high; and the lower town, which partly surrounds it. Of late years buildings of the European type have multiplied, and the older ones suffered to fall into decay. The chief are the royal and episcopal palaces, the government buildings, the cathedral, barracks, bazars, National theater, and various educational institutions. Pop. about 91,000. It manufac tures carpets, silk stuffs, hardware, cutlery, and saddlery; and carries on an active trade. Being the key of Hungary, it was long an object of fierce contention between the Austrians and the Turks, remaining, however, for the most part, in the hands of the Turks until its evacuation by them in 1867. As a result of the treaty of Berlin (July, 1878) it became the capital of Serbia. In the World War (1914-1918) Belgrade suffered heavily from bombardments by the Austrians in 1914-1915-1916. The Austrians captured it twice and were driven out by Serbian troops, but with the help of Germans and Bulgars held it from the third year of the war to the close. See SERBIA; WORLD WAR.
