The Central Powers (German: Mittelmächte; Hungarian: Központi hatalmak; Turkish: İttifak Devletleri or Bağlaşma Devletleri; Bulgarian: Централни сили Tsentralni sili), consisting of Germany, Austria-Hungary, the Ottoman Empire and Bulgaria – hence also known as the Quadruple Alliance (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, after which it was dissolved. 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.
