Why was their tension in europe prior to WW1?

The German Schleiffen plan, increasing militarism or nationalism and the assassination of Archduke Franz Ferdinand are all famous flashpoints, but there are many more. This article explains some of the lesser known causes of tension in Europe before World War One. Fear of Germany's growing strength encouraged Russia and France to enter into alliance in 1893. ... The new and unlikely friendship between these three powers heightened German fears of 'encirclement' and deepened the divide among the European powers. Imperial rifts worsened these divisions and tensions. Austria-Hungary wanted to suppress Serbian nationalism and to strengthen the unity of its empire, especially in the Balkans. Germany supported Austria-Hungary in its war on Serbia. It also sought greater influence in Europe, primarily by reducing the strength of France and Russia, and more colonial possessions.
