declared war

Formally began conflict

Declared war is armed conflict formally announced by a government through official channels, typically a legislative act.

The phrase distinguishes conflicts with legal declarations from undeclared hostilities: The last time Congress declared war was World War II.

The term often appears in discussions of constitutional war powers and international law.
