Bosnian Crisis in the context of "Bosnia Vilayet"

The League of the Balkans was a quadruple alliance formed by a series of bilateral treaties concluded in 1912 between the Eastern Orthodox kingdoms of Greece, Bulgaria, Serbia and Montenegro, and directed against the Ottoman Empire, which still controlled much of Southeastern Europe.

The Balkans had been in a state of turmoil since the early 1900s, with years of guerrilla warfare in Macedonia followed by the Young Turk Revolution, the protracted Bosnian Crisis, and several Albanian Uprisings. The outbreak of the Italo-Turkish War in 1911 had further weakened the Ottomans and emboldened the Balkan states. Under Russian influence, Serbia and Bulgaria settled their differences and signed an alliance, which was originally directed against Austria-Hungary, on 13 March 1912, but by adding a secret chapter to it essentially redirected the alliance against the Ottoman Empire. Serbia then signed a mutual alliance with Montenegro, and Bulgaria did the same with Greece.

The assassination of Archduke Franz Ferdinand was one of the key events that led to World War I. Archduke Franz Ferdinand of Austria, heir presumptive to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, were assassinated on 28 June 1914 by Bosnian Serb student Gavrilo Princip. They were shot at close range while being driven through Sarajevo, the provincial capital of Bosnia and Herzegovina, formally annexed by Austria-Hungary in 1908.

Princip was part of a group of six Bosnian assassins together with Muhamed Mehmedbašić, Vaso Čubrilović, Nedeljko Čabrinović, Cvjetko Popović and Trifko Grabež coordinated by Danilo Ilić; all but one were Bosnian Serbs and members of a student revolutionary group that later became known as Young Bosnia. The political objective of the assassination was to free Bosnia and Herzegovina of Austro-Hungarian rule and establish a common South Slav ("Yugoslav") state. The assassination precipitated the July Crisis, which led to Austria-Hungary declaring war on Serbia and the start of World War I.

The 1900s (pronounced "nineteen-hundreds") was the decade that began on January 1, 1900, and ended on December 31, 1909. The Edwardian era (1901–1910) covers a similar span of time. The term "nineteen-hundreds" is sometimes also used to mean the entire century from January 1, 1900, to December 31, 1999 (the years beginning with "19").

The Scramble for Africa continued, with the Orange Free State, South African Republic, Ashanti Empire, Aro Confederacy, Sokoto Caliphate and Kano Emirate being conquered by the British Empire, alongside the French Empire conquering Borno, the German Empire conquering the Adamawa Emirate, and the Portuguese Empire conquering the Ovambo. Atrocities in the Congo Free State were committed by private companies and the Force Publique, with a resultant population decline of 1 to 15 million. From 1904 to 1908, German colonial forces in South West Africa led a campaign of ethnic extermination and collective punishment, killing 24,000 to 100,000 Hereros and 10,000 Nama. The First Moroccan and Bosnian crises led to worsened tensions in Europe that would ultimately lead to World War I in the next decade. Cuba, Bulgaria, and Norway became independent.
