The First World War occurred from 1914 to 1918. In terms of human [[history of technology|technological history]], the scale of World War{{nbsp}}I was enabled by the technological advances of the [[Second Industrial Revolution]] and the resulting [[globalization]] that allowed global power projection and [[mass production]] of military hardware. It had been recognized that the complex system of opposing [[military alliance]]s (the [[German Empire|German]] and [[Austro-Hungarian Empire|Austro-Hungarian]] Empires against the [[British Empire|British]], [[Italian Empire|Italian]], [[Russian Empire|Russian]], and [[French colonial empire|French]] Empires) was likely, if war broke out, to lead to a worldwide conflict. That caused a very minute conflict between two countries to have the potential to set off a [[domino effect]] of alliances, triggering a world war. The fact that the powers involved had large [[colonial empire|overseas empires]] virtually guaranteed that such a war would be worldwide, as the colonies' resources would be a crucial strategic factor. The same strategic considerations also ensured that the combatants would strike at each other's colonies, thus spreading the wars far more widely than those of [[pre-Columbian]] times. {{explain|date=December 2022}}

[[War crimes]] were perpetrated in World War I. [[Chemical weapons in World War I|Chemical weapons]] were used in the war despite the [[Hague Conventions of 1899 and 1907]] having outlawed the use of such weapons in warfare. The [[Ottoman Empire]] was responsible for the [[Armenian genocide]], during the First World War, as well as other war crimes.
