Abstract
By the end of the 19th century, Europe divided into two alliances, because the probability of a war had increased. On one hand, the Triple Entente was settled in 1907 and constituted of Great-Britain, France and Russia. On the other hand, the Triple Alliance was implemented in 1891, composed of Germany, Italy and the Empire of Austria-Hungary. Some confrontations between these two rival entities occurred. Thus, Europe totally bipolarized before the Great War, which allowed the governments of these countries to prepare their population for the conflict.
