A declaration of war is a formal act by which one nation goes to war against another. The declaration is a performative speech act (or the signing of a document) by an authorized party of a national government in order to create a state of war between two or more states.
The legality of who is competent to declare war varies between nations and forms of government. In many nations, power is given to the head of state or sovereign; in other cases, something short of a full declaration of war, such as a letter of marque or a covert operation, may authorise war-like acts by privateers or mercenaries. The official international protocol for declaring war was defined in the Hague Convention (III) of 1907 on the Opening of Hostilities.
Since 1945, developments in international law such as the United Nations Charter, which prohibits both the threat and use of force in international conflicts, have made declarations of war largely obsolete in international relations. In addition to this, non-state or terrorist organisations may claim to or be described as "declaring war" when engaging in violent acts. These declarations may have no legal standing in themselves, but may still act as a call to arms for supporters of these organisations.

“The trumpets sound, the banners fly,
The glittering spears are ranked ready;
The shouts o’ war are heard afar,
The battle closes thick and bloody;
But it’s no the roar o’ sea or shore
Wad mak me langer wish to tarry;
Nor shout o’ war that’s heard afar,
Its leaving thee, my bonnie Mary.”
