The Central Powers were originally the German Empire and the Austro-Hungarian Empire, subsequently joined by the Ottoman Empire, and Bulgaria, who were all allies in The Great War. The first two empires were located between the Russian Empire and Romania in the east, France in the west, and Serbia, Montenegro and Italy in the south.
Road to War
The German and Austro-Hungarian Empires concluded a defensive alliance treaty on October 7, 1879, being joined by Italy on May 20, 1882, forming the Triple Alliance. It was formally redrafted on December 5, 1912. Romania joined the Alliance on February 5 & 26, ratified at Bucharest on March 8, 1913.
With the murders on 28 June, 1914 of the heir to the Austro-Hungarian thrones, the Archduke Franz-Ferdinand, and his wife, in Sarajevo by Serbian terrorists, armed and expedited by agents of the Serbian Government in Belgrade the Vienna government served an ultimatum upon the Serbs, which the latter declined to fully accept, which led to the outbreak of war between those two States on July 28, 1914. On the same day Montenegro said they would "co-operate" with Serbia.
The Austro-Hungarian and German requests for Italian support were rejected by the Italian Government arguing that Austria's declaration of war on Serbia was an aggressive act and a breach of Article 7 of the Treaty which intimated they should have consulted all Alliance partners first, ignoring the obvious aggression of Serbia with its organised murders of the Austrian heir to the throne of Austria-Hungary. However, Italy had its eyes on the Trentino, and Adriatic & Aegean seas, and were seeking what they called "compensation" for supporting the Alliance. On July 31, The German Ambassador at Rome reported to Berlin that Italy's Marquis San Giuliano told him that Italy was declaring herself neutral. In the end Italy betrayed her former allies by entering The Great War on May 23, 1915, on the side of the Western Allies, Russia, and Romania (who also changed sides using similar arguments to the Italians..)
Imperial Russia, having suffered a humiliating defeat on land and sea in the 1905 Russo-Japanese War, and seeing herself as the leader of the Pan-Slav Movement., had encouraged the Serbs by giving them a 'blank cheque' of guaranteed support, began mobilising its forces from mid-July against Austria-Hungary, not making a formal announcement of it until July 31st, and also Germany. Russia had been conspiring with France since at least 1891 for a decisive war against the two central powers each with their own objectives. The Russians proceeded to move vast armies to the borders of both Germany and Austria-Hungary and the latter, which had only partially mobilised - against Serbia, was obliged to fully mobilise on July 31 to protect its eastern and northern borders.. France then mobilised against Germany on August 1st.
Germany was the last of the European powers to mobilise, on August 2.. In military terms, mobilisation is war and a declaration becomes a mere formality. Rather surprisingly, Belgium had mobilised the day before Germany!
Two huge Russian armies invaded Germany (East Prussia) on August 2nd, and Germany accordingly declared war on them and their ally, France.. (Austria-Hungary's formal declaration of war with Russia was not made until August 5th.).
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, invading Serbia in support of Austro-Hungarian forces in October 1915.
Montenegro was first out of the war, requesting an armistice on January 12, 1916 following an Austro-Hungarian joint army and naval offensive. The previous year the Serbian army had been forced into retreat and "virtually annihilated" by Austro-Hungarian forces, survivors fleeing to Corfu.
The Central Powers decisively defeated Russia, who sued for peace and signed the Treaty of Brest-Litovsk in March 1918 and left The Great War. On March 5, a defeated Romania signed a preliminary Peace Treaty also with the Central Powers, concluding with the Treaty of Bucharest on May 7th.
Bulgaria, however, was the first Central Power to agree an armistice with the Allies, on September 29, 1918, following a successful French-led Allied advance, using remnants of the Serb army, Greeks, four battalions of French Black troops from Senegal and six squadrons of Moroccans, smashed through the Macedonian Front.
Austria-Hungary concluded separate ceasefires with the Western Allies during the first week of November following the commencement of the disintegration of the Habsburg Empire late in the previous month, and Germany signed the Armistice ending the war on the morning of 11 November, 1918, after a succession of advances in northern France since August by the British and their Imperial Forces, the French and, latterly, the arrival of two million American troops.
It is generally accepted by most historians that the treatment of the Central Powers at the 1919 Paris Peace Conference and the dictated Peace Treaties destroying their empires was wrong and were a direct cause of World War II.
