"World Wars" redirects here. For the two 20th century conflicts, see World War I and World War II. For the possibility of a third world war, see World War III. For the series of novels by Harry Turtledove, see Worldwar. A world war is a war affecting the majority of the world's most powerful and populous nations. World wars span multiple countries on multiple continents, with battles fought in multiple theaters, and last for multiple years. The term has usually been applied to two conflicts of unprecedented scale that occurred during the 20th century, World War I (1914–1918) and World War II (1939–1945), although in retrospect a number of earlier conflicts may be regarded as "world wars". The other most common usage of the term is in the context of World War III, a phrase usually used to describe any hypothetical future global conflict.

The Oxford English Dictionary cites the first known usage in the English language as being in April 1909, in the pages of the Westminster Gazette.

It was recognized that the complex system of opposing alliances—the German Empire, Austria-Hungary, and the Ottoman Empire vs. the French Third Republic, the Russian Empire, and the British Empire was likely to lead to a global conflict in the event of war breaking out. The fact that the powers involved had large overseas empires virtually guaranteed that a conflict would be global, as the colonies' resources would be a crucial strategic factor. The same strategic considerations also ensured that the combatants would strike at each others' colonies, thus spreading the fighting far more widely than in the pre-colonial era. Other languages have also adopted the "World War" terminology; for instance, in French, the two World Wars are the Guerres Mondiales; in German, the Erste und Zweite Weltkrieg (World War I was only known or commonly recognized in public as der Weltkrieg in Germany when it was over, while prior the word was rather used in the more abstract meaning of "a global conflict"); in Russian the мировые войны (miroviye voyni); in Spanish the Guerra Mundial and so on.

The term First World War was used in the book The First World War: A Photographic History, edited by playwright and war veteran Laurence Stallings and published in 1933.2 The term "World War I" was invented by Time magazine in its issue of June 12, 1939.3 In that same issue, the term World War II was first used speculatively by Time magazine to describe the upcoming war.4 The first use for the actual war came in its issue of September 11, 1939.5 Earlier worldwide conflicts Other examples suitable to be classified as world wars in terms of their intercontinental and intercultural scope are the Mongol invasions leading to the Mongol Empire, which spanned Eurasia from China, Japan, and Korea to Persia, Mesopotamia, the Balkans, Hungary and Russia; the Ottoman-Habsburg wars during the 16th century; and the Dutch–Portuguese War from the 1580s to the 1650s, which was fought throughout the Atlantic, Brazil, West Africa, Southern Africa, the Indian Ocean, Malaysia, India and Indonesia. Other wars in earlier periods that saw conflict across the world have been considered world wars by some: War of the Spanish Succession (1701–1713)67 Seven Years' War (1756–1763),89 which Winston Churchill called "the first world war" in A History of the English-Speaking Peoples The American Revolutionary War, fought between Britain and her colonies, drew in the help of many powers such as Spain and France. French Revolutionary Wars (1792–1802) and the Napoleonic Wars (1803–1815).citation needed

Prior to the late 19th century, the concept of a world war would not have had much meaning. The Asian powers of India, China and Japan did not act outside their own territory. India was an early target of the creation of trade colonies due to its strategic importance on the maritime equivalent of the Silk Road to the East Indies and China while both China and Japan were able to remain mostly isolationist until the 19th century. The European conflicts of earlier centuries were essentially quarrels between powers which took place in fairly limited, though sometimes far-flung, theatres of conflict. Where native inhabitants of other continents were involved, they generally participated as local auxiliaries rather than as allies of equal status, fighting in multiple theatres. For instance, in Britain's wars against France, Native Americans assisted both European powers on their own ground rather than being shipped to continental Europe to serve as allied troops there. By contrast, during the World Wars, millions of troops from Africa, Asia, North America and Australasia served alongside the colonial powers in Europe and other theatres of war.

The two World Wars of the 20th century took place on almost every populated continent on Earth. Many of the nations who fought in the First World War also fought in the Second, although not always on the same sides. Some historians have characterized the World Wars as a single "European civil war" spanning the period 1914–1945.citation needed However, this concept overlooks the war in the Far East caused by Japan's programme of territorial expansion, which started independently of events in Europe. The World Wars were made possible, above all else, by a combination of fast communications (such as the telegraph and radio) and fast transportation (the steam ship and railroad). This enabled military action to be coordinated rapidly over a very wide area and permitted troops to be transported quickly in large numbers on a global scale. Effects of the World Wars The two World Wars of the 20th century caused unprecedented casualties and destruction across the theatres of conflict. The numbers killed in the wars are estimated at between 60 and 100 million people. Unlike in most previous conflicts, civilians suffered as badly as or worse than soldiers, and the distinction between combatants and civilians was often erased.

The outcome of the World Wars had a profound effect on the course of world history. The old European empires collapsed or were dismantled as a direct result of the wars' crushing costs and in some cases the defeats of imperial powers. The modern international security, economic and diplomatic system was created in the aftermath of the wars. Institutions such as NATO, the United Nations and the European Union were established to "collectivise"citation needed international affairs, with the explicit aim of preventing another outbreak of general warcitation needed. The wars also greatly changed the course of daily life. Technologies developed during wartime had a profound effect on peacetime life as well—for instance, jet aircraft, penicillin, nuclear energy, and electronic computers. Since the atomic bombings of Hiroshima and Nagasaki during World War II, there has been a widespread and prolonged fear of a Third World War between nuclear-armed superpowers. I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones. “ ” Albert Einstein (1947)1011 Subsequent world wars World War III is a hypothetical successor to World War II and is often suggested to be nuclear and devastating in nature. This war is anticipated and planned for by military and civil authorities, and explored in fiction in many countries. Concepts range from purely conventional scenarios or a limited use of nuclear weapons to the destruction of the planet. World War IV is sometimes mentioned as a hypothetical successor to World War III or as a plot element in books, movies or video games.

Former government officials, politicians and authors have attempted to apply the labels of WW III, WW IV, and WW V to various military engagements and diplomatic stand-offs since the close of WW II, such as the Korean War or the War on Terror. Among these are former American and French government officials James Woolsey12 and Alexandre de Marenches,13 author Elliot Cohen14 and zapatist leader Subcomandante Marcos.15 Despite their efforts, none of these wars are commonly considered world wars. The Second Congo War has been called "Africa's World War" for the number of countries involved.
