why did great britain france and russia formed the triple entente in 1907
Triple Entente Historians continue to debate the importance of the alliance system as one of the causes of World War I. At the start of World War I in 1914, all three Triple Entente members entered it as Allies against the Central Powers: Germany and Austria-Hungary.[1]
Central Powers The Central Powers (German: Mittelmächte; Hungarian: Központi hatalmak; Turkish: İttifak Devletleri / Bağlaşma Devletleri; Bulgarian: Централни сили, translit. Tsentralni sili), consisting of Germany, Austria-Hungary, the Ottoman Empire and Bulgaria – hence also known as the Quadruple Alliance[1] (German: Vierbund) – was one of the two main factions during World War I (1914–18). It faced and was defeated by the Allied Powers that had formed around the Triple Entente. The Powers' origin was the alliance of Germany and Austria-Hungary in 1879. The Ottoman Empire and Bulgaria did not join until after World War I had begun, although the Ottoman Empire retained close relations with both Germany and Austria-Hungary since the beginning of the 20th century.
