Debellatio Law and Legal Definition

Debellatio means the act of conquering or subduing. The term indicates end of a war caused by complete destruction of a hostile state. For example, the Second World War ended with a complete breakup of the German Reich. The term means complete subjugation of a belligerent nation. This involves a loss of sovereignty. It is a totality of military defeat in a war. The acquisition of a territory after a war in the absence of any peace treaty, because the defeated state has ceased to exist, is known as debellatio or subjugation.
