Starting with the movement of Austria against Servia, after the assassination of the Archduke Ferdinand, there lined up as a consequence of the alliances formed between the powers, the countries referred to in preceding chapters. The triple alliance was originally an agreement between Germany, Austria-Hungary and Italy, to strengthen their positions, and the Triple Entente consisted of agreements between France, England and Russia.
INVASION OF BELGIUM.
Briefly, the invasion of Belgium by Germany, and her ambitions in the southeast, where Russia had what amounted to protectorate relations, drew first France, England and Russia into the strife, and step by step there became involved nation after nation. The steps, marked by the declarations of war, were as follows: On July 28, 1914, Austria declared war on Servia, and on August 1 Germany made the declaration against Russia. Next Germany turned upon France, on the third day of August, and also on Belgium, whereupon, on the following day, Great Britain declared war on Germany; a day later Austria-Hungary issued the mandate against Russia, and two days later, or on August 8, Montenegro declared war on Austria. Austria accepted the challenge, and then Servia took up the cudgel against Germany. France made formal declaration of war on Austria-Hungary and by the end of August Montenegro had declared against Germany; Great Britain on Austria; Japan on Germany; Austria on Japan; Austria on Belgium. Later, or early in November, Russia declared herself against Turkey, as did France and Great Britain.
For six months the battle raged and the rest of the world regarded the result with grave concern until in May of 1915 Italy, having renounced her alliance with Germany and Austria, declared war first on Austria, then on Turkey. In the fall of 1915 Servia took up arms against Bulgaria, as did Great Britain, France, Italy and Russia. Then Germany declared against Portugal, whose government replied in kind; Austria followed Germany in the alignment and finally, in August, 1916, there were exchanges of sharp "courtesies"—the complete severance of all diplomatic relations and open warfare—between Roumania and Austria-Hungary; then between Bulgaria and Roumania, with the consequent alignment of the Central Powers. Italy had also made her declaration against Germany specific. So for nine months the war waged with terrible bitterness until on April 6, the United States, by the proclamation of President Wilson, was finally at war with Germany.
IN THE NATURE OF MERE FORMALITIES.
These steps were, in many instances, in the nature of formalities, for the relationships of some of the countries involved placed them in the position of practically being at war before formal announcement was made. The position then, was that Germany, Austria-Hungary and Turkey were supported by Bulgaria, who was anxious to get redress for having been cheated out of what she regarded as her rightful possessions in the settlement of the Balkan war question. Those aligned on the other side were England, France, Russia, Montenegro, Italy, Belgium (which had been making defensive warfare in keeping with her desire to be true to her neutral pledges); Servia, Roumania, Japan, Portugal, the United States, the little principality of Monaco, which is best known as the seat of Monte Carlo, the great gambling center of Europe, and San Marino, a similar "patch" on the map of Europe. Brazil, Guatemala, and the little Republic of Cuba also aligned themselves against Germany in support of the Allies, though there was no actual engagement of their forces. Thus there could be counted as at war against the Central Powers in June, 1917, sixteen countries.
Most interesting of all the countries involved were those belonging to the Balkan group and centering in southeastern Europe. The Balkan nations, Bulgaria, Servia, Montenegro, with Greece, paved the way for their entrance into the conflict when they formed an alliance, in 1912, for common protection, particularly for the enforcement of one of the provisions of the Berlin Treaty, guaranteeing local government to the Bulgar and Serbian colonies in Macedonia. Montenegro began war on Turkey in October, and Bulgaria, Servia and Greece joined and drove the Turks out of many of their strongholds.
