(a) The European political doctrine of the “Balance of Power,” which was the outgrowth of the Napoleonic wars, and received its first stamp of approval at the Congress of Vienna in 1815, which settled the important boundaries of the map of Europe for more than half a century afterward. Subsequently, the “great powers” of Europe assumed the point of view that any acquisition of power, territory or population by any one of them entitled all the others to compensation; so that the relative strength and importance might not be disturbed. This rule has been applied to every important war since Napoleon’s time, and any threatened disturbance of this “balance” has always had in it the germ of a general conflict. Hence arose the historic “alliances,” known as the Triple Alliance, on the one hand, and the Triple Entente, comprising France, Russia and Great Britain, on the other.

(b) Militarism, so-called, with its attendant jealousies and obstacles to social and economic reforms, and which might be said to be the direct fruits of the “balance of power” doctrine, as is also the doctrine of the “guaranteed neutrality” of certain small countries of Europe, which astute European diplomacy created for the purpose of “buffer” states.

Military Leaders: (1) Kitchener, French, Haig, Joffre, Grand Duke Nicholas, Kouropatkin, Brusiloff, Admirals Fisher and Jellicoe; (2) Emperor William, Hindenburg, Mackensen, Kluck, Falkenhayn, Archduke Frederick, Hoetzendorf, Crown Prince Frederick William, Admiral Tirpitz, Crown Prince Rupprecht, Enver Pasha.

Chief Theaters of Action: (1) Belgium; (2) Northern France; (3) Poland; (4) Dardanelles; (5) Servia and Balkans; (6) Roumania; (7) Austro-Italian Front; (8) Lithuania; (9) North Sea and Inlets; (10) Mediterranean; (11) German Colonial Possessions throughout the world.

Results: Except for the loss of Germany’s Colonial Possessions, the results of the war to date (1917) largely preponderate in favor of the Teutonic Allies—the land campaigns being almost overwhelmingly in their favor. (See further Great Battles of the World.)
