The term debellatio or "debellation" (Latin 'defeating, or the act of conquering or subduing', literally, 'warring (the enemy) down', from Latin bellum 'war') designates the end of war caused by complete destruction of a hostile state.
Israeli law-school professor Eyal Benvenisti defines it as "a situation in which a party to a conflict has been totally defeated in war, its national institutions have disintegrated, and none of its allies continue to challenge the enemy militarily on its behalf".
[1] In some cases debellation ends with a complete dissolution and annexation of the defeated state into the victor's national territory, as happened at the end of the Third Punic War with the defeat of Carthage by Rome in the 2nd century BC.
[2] The unconditional surrender of Nazi Germany, in the strict sense only the German Armed Forces, at the end of World War II was at the time accepted by most authorities as a case of debellatio as: Other authorities, supported in the judgements of the German Federal Constitutional Court, have argued that a German state remained in existence from 1945 to 1949, albeit dormant and without any institutional or organisational component, on the basis that: The official position of the Allied-occupied government as well all subsequent German governments since has been and remains that the Nazi regime was "illegal"; with laws and verdicts imposed during the Third Reich regularly being declared facially invalid.
[11][12][13] Following the surrender, the Nazi party was and remains to this day outlawed; various restrictions were imposed on former Nazi party members including bans on running for or holding public office, though these laws were later scaled back.
