World War III (WWIII or WW3 or World War Three), also known as the Third World War or the Great Global Offensive, was a global war centred in Eurasia that began on 28 July 2015 and lasted until 11 November 2019. More than 20 million combatants and 14 million civilians died as a result of the war, 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..
