The most important, although the second smallest, of the five great land divisions of the globe; is, from a geographical point of view, a peninsula of Asia; the Caspian Sea, Ural River and mountains, form its Asiatic boundary, while on the other three sides it is washed by the Mediterranean on the S., Atlantic on the W., and Arctic Ocean on the N.; its coast-line is so highly developed that to every 190 sq. m. of surface there is 1 m. of coast; this advantage, combined with the varied adaptability of its land, rivers, and inland seas, and its central position, has made it the centre of civilisation and the theatre of the main events of the world's history. Its greatest length is 3370 m. from Cape St. Vincent to the Urals, and its greatest breadth 2400 m. from Cape Matapan to Nordkyn, while its area is about 3,800,000 sq. m.; it is singularly free from wild animals, has a fruitful soil richly cultivated, and possesses in supreme abundance the more useful metals. Its peoples belong to the two great ethnological divisions, the Caucasian and Mongolian groups; to the former belong the Germanic, Romanic, Slavonic, and Celtic races, and to the latter the Finns, Magyars, and Turks. Christianity is professed throughout, except amongst the Jews, of whom there are about six millions, and in Turkey, where Mohammedanism claims about seven millions; of Catholics there are about 155 millions, of Protestants 85, and of the Greek Church 80. Amongst the 18 countries the form of government most prevailing is the hereditary monarchy, resting more and more on a wide representation of the people.
