Pie chart showing military deaths of the 'Central Powers'.
The 'Central Powers' were the states of
Germany,
Austria-Hungary, the
Ottoman Empire, and
Bulgaria, which fought against the
Allies during
World War I. They are called this because they all were located between the
Russian Empire in the east and
France and the
United Kingdom in the west.
Germany and Austria-Hungary became allies on
7 October 1879, being joined subsequently (
20 May 1882) (see
Triple Alliance) by
Italy, which intended to limit the alliance to defensive purposes. At the beginning of the war, the German and Austro-Hungarian request of Italian intervention was rejected by the Italian Government based on the fact that Austria had declared war on
Serbia, so it was not a defensive war. Italy entered World War I on
May 23,
1915, on the Allies' side.
Following the outbreak of
European war in August
1914, the Ottoman Empire intervened at the end of October against Russia, provoking declarations of war by the
Triple Entente powers--Russia, France and the United Kingdom.
Bulgaria, still resentful after its
defeat in July
1913 at the hands of Serbia,
Greece,
Romania and the Ottoman Empire, was the last nation to enter the war against the Entente, invading Serbia in conjunction with German and
Austro-Hungarian forces in October 1915.
Other movements supported the efforts of the Central Powers for their own reasons, such as the Irish Nationalists who launched the
Easter Rising in
Dublin in April
1916; they referred to their "gallant allies in Europe". In
1917-
18 the
Finns under
C.G.E. Mannerheim and the
Ukrainian and
Lithuanian nationalists had a common cause against Russia. The Ottoman Empire also had its own ally in
Azerbaijan. The two nations fought alongside each other under the
Army of Islam in the
Battle of Baku.
Bulgaria signed an armistice with the Allies on
29 September,
1918, following a successful Allied advance in
Macedonia. The Ottoman Empire followed suit on
30 October,
1918 in the face of British and
Arab gains in
Palestine and
Syria.
Austria and
Hungary concluded ceasefires separately during the first week of November following the disintegration of the
Habsburg Empire, and Germany signed the armistice ending the war on the morning of
11 November,
1918 after a succession of advances by Canadian,
Belgian, British, French and
US forces in north-eastern France and Belgium.
