World War IWorld War I or the First World War, often abbreviated as WWI or WW1, known contemporaneously as the Great War, was a major global conflict lasting from 1914 to 1918. It was fought between two coalitions, the Allies and the Central Powers. Fighting took place throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. The first decade of the 20th century saw increasing diplomatic tension between the European great powers.
Allies of World War IThe Allies, or the Entente Powers, were 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). By the end of the first decade of the 20th century, the major European powers were divided between the Triple Entente and the Triple Alliance. The Triple Entente was made up of the United Kingdom, France, and Russia.
Alexander I of YugoslaviaAlexander I (Александар I Карађорђевић, aleksǎːndar př̩ʋiː karad͡ʑǒːrd͡ʑeʋit͡ɕ; – 9 October 1934), also known as Alexander the Unifier, was King of the Serbs, Croats and Slovenes from 16 August 1921 to 3 October 1929 and King of Yugoslavia from 3 October 1929 until his assassination in 1934. His reign of 13 years is the longest of any monarch of the Kingdom of Yugoslavia. Born in Cetinje, Montenegro, Alexander was the second son of Peter and Zorka Karađorđević.
Causes of World War IThe identification of the causes of World War I remains a debated issue. World War I began in the Balkans on July 28, 1914, and hostilities ended on November 11, 1918, leaving 17 million dead and 25 million wounded. Moreover, the Russian Civil War can in many ways be considered a continuation of World War I, as can various other conflicts in the direct aftermath of 1918. Scholars looking at the long term seek to explain why two rival sets of powers (the German Empire and Austria-Hungary against the Russian Empire, France, the British Empire and later the United States) came into conflict by 1915.
MobilizationMobilization is the act of assembling and readying military troops and supplies for war. The word mobilization was first used in a military context in the 1850s to describe the preparation of the Prussian Army. Mobilization theories and tactics have continuously changed since then. The opposite of mobilization is demobilization. Mobilization became an issue with the introduction of conscription, and the introduction of the railways in the 19th century.
Battle of CerThe Battle of Cer was a military campaign fought between Austria-Hungary and Serbia in August 1914, starting three weeks into the Serbian Campaign of 1914, the initial military action of the First World War. It took place around Cer Mountain and several surrounding villages, as well as the town of Šabac. The Battle of Cer is known as the first Allied victory over the Central Powers in the First World War.
Georg von HertlingGeorg Friedrich Karl Freiherr von Hertling, from 1914 Count von Hertling, (31 August 1843 – 4 January 1919) was a German politician of the Catholic Centre Party. He was foreign minister and minister president of Bavaria, then chancellor of the German Reich and minister president of Prussia from 1 November 1917 to 30 September 1918. He was the first party politician to hold the two offices; all the others were non-partisan. Hertling's Catholicism played an important role in both his academic and political life.
Assassination of Archduke Franz FerdinandThe assassination of Archduke Franz Ferdinand is considered one of the key events that led to World War I. Archduke Franz Ferdinand of Austria, heir presumptive to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, were assassinated on 28 June 1914 by Bosnian Serb student Gavrilo Princip. They were shot at close range while being driven through Sarajevo, the provincial capital of Bosnia-Herzegovina, formally annexed by Austria-Hungary in 1908.
Alfred von TirpitzAlfred Peter Friedrich von Tirpitz (ˈalfʁeːt fɔn ˈtɪʁpɪt͡s; 19 March 1849 – 6 March 1930) was a German grand admiral, Secretary of State of the German Imperial Naval Office, the powerful administrative branch of the German Imperial Navy from 1897 until 1916. Prussia never had a major navy, nor did the other German states before the German Empire was formed in 1871. Tirpitz took the modest Imperial Navy and, starting in the 1890s, turned it into a world-class force that could threaten Britain's Royal Navy.
Russian EmpireThe Russian Empire, also known as Imperial Russia, was the final period of the Russian monarchy from its proclamation in November 1721, until its dissolution in late 1917. It consisted of most of northern Eurasia. The Empire succeeded the Tsardom of Russia following the Treaty of Nystad. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China.
