This undermined the system of alliances bismarck had established to prevent war on two fronts. In 1907, the Anglo-Russian Entente was agreed in an attempt to resolve a series of long-standing disputes over Persia, Afghanistan and Tibet and to end its rivalry in Central Asia, called The Great Game.  and helped allay British fears about the Baghdad Railway, which would help German expansion in the Middle East. Until the early 1900s, Britain was more concerned with Russia and France than with Germany. Relations between Britain and Germany have been very good. However, this began to change. When Emperor Wilhelm II took control of Germany, he strove to make Germany a great power. He felt that Russia revolved around Germany to the east and France to the west. As a result, it has strengthened its armed forces. The France and Russia feared Germany and did the same. During the 1900s, all the great powers of Europe began to build their armies and fleets.
Britain`s policy was to maintain a balance of power in Europe. Germany`s growing strength and apparent quest for “world power” status convinced Britain to ally itself with its traditional rivals: France in 1904 and Russia in 1907. This united Britain, France and Russia in the “Triple Entente” and fueled German fears of “encirclement.” German nationalists saw Britain as an obstacle to their global ambitions, and German generals increasingly feared Russia`s growing military threat. In 1882, Germany, Austria-Hungary and Italy formed the triple alliance. The three countries agreed to support each other if attacked by France or Russia. The France felt threatened by this alliance. Britain was also concerned about the growth of the German navy, and in 1904 both countries signed the Entente Cordiale. The aim of the alliance was to promote cooperation against the perceived threat posed by Germany. Europe was an armed camp in 1914; its politics are dominated by two rival alliances.
The creation of a united Germany in 1871 had disrupted the old “balance of power” in Europe. The Triple Entente is the alliance formed in 1907 between the United Kingdom of Great Britain and Ireland, the Third French Republic and the Russian Empire after the signing of the Anglo-Russian Entente. The United Kingdom already had the Entente Cordiale with the France since 1904, while the France had formed the Franco-Russian alliance in 1894. Founded in 1882, the Triple Alliance posed a disturbing threat, so the three nations united in a pact to protect them from encroachment or attack. The Entente was in itself a defensive alliance.  Fear and mistrust drove the three nations to seek a viable partnership, while the German navy and army continued to grow in size and power.  With the outbreak of World War I, the world would finally see both alliances strike. The doctrine of the balance of power was behind the alliance that was supposed to keep the peace. However, this did not sufficiently take into account the Triple Alliance`s ambitions for an empire inside and outside Europe.
Russia had already been a member of the League of three Emperors, which was allied with Austria-Hungary and Germany in 1873. The alliance was part of German Chancellor Otto von Bismarck`s plan to diplomatically isolate the France; he feared that the revanchist aspirations of the France would lead him to try to recover his losses of 1871 from the German-French War.  The alliance also served to oppose socialist movements such as the First International, which conservative leaders found troubling.  However, the League had great difficulties with the growing tensions between Russia and Austria-Hungary, especially over the Balkans, where the rise of nationalism and the continued decline of the Ottoman Empire left many former Ottoman provinces fighting for independence.  In order to counter Russian and French interests in Europe, the double alliance between Germany and Austria-Hungary was concluded in October 1879 and with Italy in May 1882. The situation in the Balkans, especially after the Serbo-Bulgarian War of 1885 and the Treaty of Berlin of 1878, which made Russia feel deceived about its gains in the Russo-Turkish War of 1877/8, prevented the renewal of the league in 1887. To prevent Russia from allying itself with the France, Bismarck signed the secret reinsurance treaty with Russia in 1887. This treaty guaranteed that both sides would remain neutral in the event of the outbreak of war.
The growing rapprochement between Russia and France and the exclusion of Bismarck from Russia from the German financial market in 1887 prevented a renewal of the treaty in 1890 and ended the alliance between Germany and Russia.  After Bismarck`s forced resignation in 1890, the young Kaiser Wilhelm embarked on his imperialist path of world politics in order to increase the empire`s influence and control over the world.   Russia had already been a member of the League of three Emperors, which was allied with Austria-Hungary and Germany in 1873. The alliance was part of Chancellor Otto von Bismarck`s plan to diplomatically isolate the France. Britain and France, both facing German imperialism, signed an agreement between them in 1904 called the Entente Cordiale. Soon after, in 1907, Russia joined the Anglo-Russian Entente to allay British fears of German expansion into the Middle East. The Triple Entente (Russian: Тройственная Антанта, Romanized: Troystvennaya Antanta, from French entente [ɑ̃tɑ̃t] means “friendship, understanding, agreement”) describes the informal understanding between the Russian Empire, the French Third Republic and Great Britain. .
