The black hand gang
Serbian nationalism increased tensions within Europe before World War I. Serbia wanted to create a pan-Slavic state in the Balkans which included Bosnia-Herzegovina, held by Austria-Hungary. Serbia was allied with Russia and Austria was allied with Germany. Russia allied with France. A war between Serbia and Austria threatened to involve the whole of Europe.
The assasination of Archduke Franz Ferdinand, heir to the throne of Austria-Hungary. He was killed by Gavrillo Princip, a slavic nationalist in Sarahevo, Bosnia in 1914. Austria-Hungary used this as an excuse to invade Bosnia.
Austria joined the Crimean war because it feared it's 43% Slavic population (by ethinicity, culture or language) would rebel as they had in the revolutions of 1848 when Russia, "mother of the Slavs," invaded the Balkans.
It started from nationalism with Seriba. They wanted to gain the Balkan peninsula because of the population of Slavic people. Russia supported the Serbian nationalism, because Russia itself was a Slavic nation. Austra-hungary disliked this idea, worrying that a Slavic state would stir rebellion among their Slavic population. Austria-Hungary annexed the Balkans. This angered Serbia. The final straw was the assassination of Franz Ferdinand. He was heir to the Austro-hungarian throne. He and his wife, Sophia, visited the capital of Bosnia. As they rode through the streets, they were shot at close range by a member of the Black Hand, a secret society committed to ridding Bosnia of Austrian rule. Austria-Hungary issued a letter to Serbia stating that they were to respect the Great powers decision regarding the Balkans. The letter also aimed demands at preventing publication of propaganda that would advocate violence, removing people behind the propaganda in the Serbian Military, arresting people on Serbian soil who were involved with the assassination plot, and preventing secret shipments of arms and explosives from Serbia to Austria-Hungary. Serbia agreed to some demands, but offered to have several others settled by and international conference. Austria rejected Serbia's offer and declared war. Russia, an ally of Serbia, mobilized troops toward the Austrian Border.
