The Battle of Kolubara was fought between Austria-Hungary and Serbia in November and December 1914, during the Serbian Campaign of 1914.
The Allies, the Entente or the Triple Entente was an international military coalition of countries led by France, the United Kingdom, Russia, the United States, Italy, and Japan against the Central Powers of Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria in World War I (1914–1918).
World War I was a global conflict between two coalitions: the Allies and the Central Powers. Fighting took place mainly in Europe and the Middle East, as well as parts of Africa and the Asia-Pacific, and was characterised by trench warfare and the use of artillery, machine guns, and chemical weapons (gas). World War I was one of the deadliest conflicts in history, resulting in an estimated 9 million military dead and 23 million wounded, plus up to 8 million civilian deaths from causes including genocide. The movement of large numbers of troops and civilians was a major factor in spreading the Spanish flu pandemic.
Naval warfare in the Mediterranean during World War I took place between the naval forces of the Entente and the Central Powers in the Mediterranean Sea between 1914 and 1918.
The Macedonian front, also known as the Salonica front, was a military theatre of World War I formed as a result of an attempt by the Allied Powers to aid Serbia, in the autumn of 1915, against the combined attack of Germany, Austria-Hungary and Bulgaria. The expedition came too late and with insufficient force to prevent the fall of Serbia and was complicated by the internal political crisis in Greece. Eventually, a stable front was established, running from the Albanian Adriatic coast to the Struma River, pitting a multinational Allied force against the Bulgarian army, which was at various times bolstered with smaller units from the other Central Powers. The Macedonian front remained stable, despite local actions, until the Allied offensive in September 1918 resulted in Bulgaria capitulating and the liberation of Serbia.
Radomir Putnik was the first Serbian Field Marshal and Chief of the General Staff of the Serbian army in the Balkan Wars and in the First World War. He served in every war in which Serbia fought from 1876 to 1917.
