This is a timeline of formal Declarations of War during World War II. A ''Declaration of War'' is a formal act by which one nation goes to war against another. The declaration is usually an act of delivering a performative speech (not to be confused with a mere ''speech'') or the presentation of a signed document by an authorized party of a national government in order to create a state of war between two or more sovereign states. The official international protocol for declaring war was defined in The Hague Peace Conference of 1907 (or Hague II).〔(''On the Opening of Hostilities'' ); 1907; Yale Law School Library; retrieved March 2014.〕 For the diplomatic maneuvering behind these events which led to hostilities between nations during World War II, see the article entitled Diplomatic history of World War II. ==List of war declarations== Below is a table showing the ''Outbreaks of Wars between Nations'' which occurred during World War II. Indicated are the dates (during the immediate build-up to, or during the course of, World War II), from which a ''de facto'' state of war existed between nations. The table shows both the "Initiator Nation(s)" and the nation at which the aggression was aimed, or "Targeted Nation(s)". Events listed include those in which there were simple diplomatic breaking of relations that did not involve any physical attack, as well as those involving overt declarations or acts of aggression.〔Note:In rare cases, war between two nations occurred twice, with an intermittent period of peace. The list here does not include peace treaties or periods of any armistices.〕 ; ; W = Formal declaration of war made.
