A world war is a war involving many or most of the world's most powerful and populous countries. World wars span multiple countries on multiple continents, with battles fought in multiple theatres. The term is applied to the two major international conflicts that occurred during the twentieth century: the First World War (1914 - 1918) and the Second World War (1939 - 1945) The Oxford English Dictionary cited the first known usage in the English language to a Scottish newspaper: the People's Journal in 1848, “A war among the great powers is now necessarily a world-war.” The term, “world war” had been used in 1850 by Karl Marx and his associate Friedrich Engels in The Class Struggles in France. Rasmus B. Anderson in 1889 described an episode in Teutonic mythology as a “world war” (Swedish: världskrig), justifying this description by a line in an Old Norse epic poem, "Völuspá: folcvig fyrst i heimi" ("The first great war in the world".) German writer August Wilhelm Otto Niemann had used the term "world war" in the title of his anti-British novel, Der Weltkrieg: Deutsche Träume (The World War: German Dreams) in 1904, published in English as The Coming Conquest of England.
