Explanation:

Paneslavism (from the Greek pān-, everything, and Slavic) was a political and cultural movement, born of a nationalist ideology, emerged in the 19th century with the aim of promoting cultural, religious and political union, as well as mutual cooperation, among all the Slavic countries of Europe.

Paneslavism was an ideology quite influenced by the romanticism and nationalism that prevailed in Europe in the mid-nineteenth century, and began to manifest itself as a political alternative in the Paneslavian Congress of Prague in 1848, the first time that political leaders of Slavic countries formulated the bases of this movement in the sense of an effective opposition against the imperialism of Austria.

Gradually, the Austro-Hungarian Empire fought Paneslavism within its domains, considering it a threat against its strategic and political interests. The Russian Empire showed some interest in promoting Paneslavism but the Austrian government permanently accused Russia of using this doctrine only as a pretext for its own expansionism, to the detriment of Austria, reaching this tension its highest point during the Russian-Turkish war of 1877 and then in the Bosnian Crisis of 1908.

Austria-Hungary precipitated the "Bosnian crisis" with the official annexation of the province of Bosnia and Herzegovina, a former Ottoman territory occupied since 1878 by Austria. This enraged the Kingdom of Serbia and its protector, the Russian Empire, which followed a policy based on Paneslavism and shared the Orthodox religion with its Slavic allies. The maneuvers of Russian diplomacy in the peace accords caused the region to destabilize, which added to the fracture that already existed in the Balkans, made the region known as the "powder keg of Europe."

Finally, The Sarajevo attack took place. It refers to the murder, on June 28, 1914, of the crown heir of the Austrian-Hungarian Empire, Archduke Francis Ferdinand of Austria, and his wife, Duchess Sofia Chotek, in Sarajevo, capital of the imperial province of Bosnia and Herzegovina. The attack was perpetrated by Gavrilo Princip, a member of the Young Bosnia group, a nationalist paneslavic movement whose objective was the emancipation of Bosnia from Austria-Hungary, which was supported by intelligence and military circles from the Kingdom of Serbia. It was the beginning of the WWI.
