The most northerly province in Austria, two-thirds the size of Scotland; is encircled by mountains, and drained by the upper Elbe and its tributaries. The Erzgebirge separate it from Saxony; the Riesengebirge, from Prussia; the Bohmerwald, from Bavaria; and the Moravian Mountains, from Moravia. The mineral wealth is varied and great, including coal, the most useful metals, silver, sulphur, and porcelain clay. The climate is mild in the valleys, the soil fertile; flax and hops the chief products; forests are extensive. Dyeing, calico-printing, linen and woollen manufactures, are the chief industries. The glassware is widely celebrated; there are iron-works and sugar-refineries. The transit trade is very valuable. The people are mostly Czechs, of the Slavonic race, Roman Catholics in religion; there is a large and influential German minority of about two millions, with whom the Czechs, who are twice as numerous, do not amalgamate; the former being riled at the official use of the Czech language, and the latter agitating for the elevation of the province to the same status as that of Hungary. Education is better than elsewhere in Austria; there is a university at Prague, the capital. In the 16th century the crown was united with the Austrian, but in 1608 religious questions led to the election of the Protestant Frederick V. This was followed by the Thirty Years' War, the extermination of the Protestants, and the restoration of the Austrian House.
