World War I
(WWI or WW1), also known as the First World War, was a
global war centred in Europe that began on 28 July 1914 and lasted until 11
November 1918. From the time of its occurrence until the approach of World War
II, it was called simply the World War or the Great War, and
thereafter the First World War or World War I. In America, it was initially
called the European War. More than 9 million combatants were
killed, a casualty rate exacerbated by the belligerents' technological and
industrial sophistication, and tactical stalemate. It was one of the deadliest
conflicts in history, paving the way for major political changes, including
revolutions in many of the nations involved.
The Great War started 100 years ago today and we
have learnt nothing since. How many countries are currently involved in wars?
