war declaration
Formal combat initiation
A war declaration is a formal announcement by a government or authority that a state of war exists between itself and another nation or entity.
Historically, declarations preceded military action and carried legal weight under international law: Congress has not issued a formal war declaration since World War II.
Modern conflicts often proceed without them, making the term somewhat archaic in practice.
