declarations of war
Formal hostility proclamations
Declarations of war are formal announcements by a government that a state of war exists between it and another nation.
Historically, such declarations preceded hostilities and carried legal significance under international law.
In the United States, Congress holds the constitutional power to declare war, though this formality has largely fallen into disuse—most modern conflicts proceed without official declarations.
The last time Congress issued a declaration of war was in 1942.
