This article is about the war as depicted in The War That Came Early series. For other versions, see World War II, World War II (Joe Steele), and Second Great War. The Second World War was a partial amalgamation of several disparate events into a global conflict. The ongoing Spanish Civil War and the Second Sino-Japanese War were eventually tied into a war in Europe that began in 1938 with the German invasion of Czechoslovakia, and quickly brought several countries into conflict across the continent. Discontent with the final outcome of World War I helped feed the conflict, as various countries sought to regain lost territory and prestige. As often is the case in war, alliances proved fluid and temporary.
