How did the war between austria-Hungary and Serbia become a world war?

Answer 1

The Russian decision to meddle in the dispute between Austria-Hungary and Serbia. Russia had no alliance, nor any treaty with Serbia that required Russia to take Serbia's part in the quarrel, particularly since the Serbian intelligence service had, in fact, sponsored the Black Hand, the terrorist group of Serbian nationalists who murdered the heir to the throne of Austria-Hungary, along with his wife. But despite the fact that the murderous Serbs were in the wrong, Russia thought of herself as the "mother of the Slavs", and therefore the Czar felt he had to take Serbia's part. This turned out to be a horrible decision for Russia, leading to the deaths of millions of Russian soldiers, followed by revolutions which ended the Romanov dynasty in Russia after several centuries, the murder of the Czar, his wife, and all their children, and seventy years of bleak, repressive communist rule for the rest of the Russians.

Germany and Austria-Hungary were allies, natural ones, with German speaking populations, as well as being neighbors. But Austria-Hunagry would have needed no German help with Serbia, as Austria-Hungary outnumbered Serbia fifty to one. The Russian decision to intervene made it a different matter entirely. Russia and France were allies, an alliance sought by France after France picked a fight with Germany when Germany was a new, just united nation, started a war, and lost in most humiliating fashion this Franco-Prussian War of 1870. Once Russia and France announced their alliance, Germany had to plan for a two front war, in the east and the west, with France in the west and Russia in the east. War with either France or Russia would mean war with both for Germany. The plan for this contingency, labored over by a generation of German staff officers, was to beat France quickly, just like they did in 1870, before Russia could get its massive army mobilized and into the field. To beat France quickly Germany would go around the French forts along the Franco-German border, and invade France by going through Belgium, and that would bring Britain into the war, with all her peoples of the British Empire.

Had Russia minded her own business in the summer of 1914, none of this would have happened, and Austria-Hungary would have administered a richly deserved drubbing to Serbia which would hardly be remembered today.
