World War I (abbreviated WWI), also known as the First World War, the Great War and The War to End all Wars was a global military conflict that took place mostly in Europe between 1914 and 1918. The main combatants were the Allied Powers, led by France, the Russian Empire, the British Empire, Serbia, Belgium, and later Italy, Romania and the United States, who fought against the Central Powers: Austria-Hungary, the German Empire, Bulgaria, and the Ottoman Empire (present day Turkey).

Much of the fighting in World War I took place along the Western Front, within a system of opposing manned trenches and fortifications (separated by a "no man's land") running from the North Sea to the border of Switzerland. On the Eastern Front, the vast eastern plains and limited rail network prevented a trench warfare stalemate from developing, although the scale of the conflict was just as large. Hostilities also occurred on and under the sea and — for the first time — in the air. More than nine million soldiers died on the various battlefields, and millions more civilians perished.

The war caused the disintegration of four empires: the Austro-Hungarian, German, Ottoman, and Russian. Germany lost its overseas empire, and states such as Czechoslovakia and Yugoslavia were created, or recreated, as in the cases of Lithuania and Poland. This contributed to a decisive break with the world order that had emerged after the Napoleonic Wars, which was modified by the mid-19th century’s nationalistic revolutions. The results of World War I would also be important factors in the development of World War II just over two decades later.

Selected event

BattleOfTannenberg2.jpg

The Battle of Tannenberg in 1914 was a decisive engagement between the Russian Empire and the German Empire in the first days of The Great War, fought by the Russian First and Second Armies and the German Eighth Army between August 17 and September 2, 1914. The battle resulted in the almost complete destruction of the Russian Second Army. A series of follow-up battles kept the Russians off-balance until the spring of 1915. The battle is notable particularly for a number of rapid movements of complete corps by train, allowing the single German Army to present a single front to both Russian Armies.

Trench knives are either purpose-made weapons, or are made from cut-down (shortened) bayonets or swords, and intended for close-quarter fighting, the design originating in the trench warfare of the First World War. They were particularly useful for trench raiding operations, along with other mêlée weapons.

Selected biography

Gavrilloprincip.jpg

Gavrilo Princip (Serbian Cyrillic: Гаврило Принцип) (pronounced (gäv´ri:lo: pri:n´tsip) (July 25, 1894 – April 28, 1918) was a Serb member of the Young Bosnia secret society who assassinated Archduke Franz Ferdinand of Austria and his wife Sophie, Duchess of Hohenberg in Sarajevo on June 28, 1914. The event, known as the assassination in Sarajevo, prompted the Austrian action against Serbia that led to World War I. He is sometimes nicknamed "The Man That Started World War I". Having been too young at the time of the assassination (19) to face the death penalty, Princip received the maximum sentence of twenty years in prison, where he was held in harsh conditions worsened by the war. He died of tuberculosis on April 28, 1918 at Theresienstadt.
