Field Marshal Lord Horatio Herbert Kitchener, 1st Earl Kitchener (24 June 1850 – 5 June 1916), was an Irish-born British Field Marshal and proconsul who won fame for his imperial campaigns and later played a central role in the early part of the First World War, although he died halfway through it.
World War I (WWI) was a global war centered in Europe that began on 28 July 1914 and lasted until 11 November 1918. It was predominantly called the World War or the Great War from its occurrence until the start of World War II in 1939, and the First World War or World War I thereafter.
It involved all the world's great powers, which were assembled in two opposing alliances: the Allies (based on the Triple Entente of the United Kingdom, France and Russia) and the Central Powers (originally centered around the Triple Alliance of Germany, Austria-Hungary and Italy; but, as Austria–Hungary had taken the offensive against the agreement, Italy did not enter into the war).
These alliances both reorganized (Italy fought for the Allies), and expanded as more nations entered the war. Ultimately more than 70 million military personnel, including 60 million Europeans, were mobilized in one of the largest wars in history. More than 9 million combatants were killed.
