Passing on to larger figures, that is to say to the total area of all the possessions of the nations involved, it will be seen that the preponderance on the part of the Allies is even greater. Thus the German Empire, inclusive of colonial possessions in Africa, in Asia, and in the Pacific, contained 1,236,600 square miles. The Austro-Hungarian Empire, as previously stated, was 261,239 square miles, there being no oversea colonies. This makes a total of 1,497,839 square miles as the total territory of the Central Powers.
Balanced against this come the enormous figures of the three great allied empires. The area of the British Empire was approximately 13,158,712 square miles, the Republic of France and her colonies 4,983,086 square miles, and the Russian Empire 8,394,018 square miles. The three empires combined thus made a total of 26,535,816 square miles, or but very little less than one-half of the total land area of the earth. These figures are compiled from the latest sources before the opening of the war, but it is to be remembered that some of the figures are approximate. For example the French possessions in Africa, of enormous extent, have not been surveyed, and there are vast stretches of Arctic Siberia and Arctic Canada which are but half explored. The small territories of Belgium and Serbia may be added to the total of the three great allied empires, and thus practically one-half of the earth on this globe was opposed to the million and a half square miles of the Central Powers.
Owing to Bulgaria's position in the Balkan Peninsula, and also owing to aggrievement following the results of former Balkan wars, Bulgaria joined the Central Powers later in the war. Turkey, also, fearing the loss of Constantinople to the Russians as a result of the coalition of the Allies, threw her forces on the side of Germany. The area of Bulgaria was only 43,000 square miles, but the Ottoman or Turkish Empire was territorially very large, containing 1,420,448 square miles, or almost as much as Germany, Austria, and Bulgaria combined. In round numbers, and for easy remembrance, it may be said that the territory of the Central Powers engaged in the war was about three million square miles.
