| The Central Powers, also known as the Central Empires, were one of the two main coalitions that fought in World War I (1914–1918). It consisted of Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria; this was also known as the Quadruple Alliance.
The Central Powers' origin was the alliance of Germany and Austria-Hungary in 1879. Despite having nominally joined the Triple Alliance before, Italy did not take part in World War I on the side of the Central Powers. The Ottoman Empire and Bulgaria did not join until after World War I had begun. The Central Powers faced, and were defeated by, the Allied Powers, which themselves had formed around the Triple Entente. |
