Central Powers 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. 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.
Axis powers The Axis powers (German: "Achsenmächte" , Japanese: 枢軸国 "Sūjikukoku", Italian: "Potenze dell'Asse" ), also known as the Axis and the Rome–Berlin–Tokyo Axis, were the nations that fought in World War II against the Allied forces. The Axis powers agreed on their opposition to the Allies, but did not completely coordinate their activity.
