The principle of every nation inhabiting its own nation state gave rise to a series of expulsions and resettlements of Germans, Poles, Ukrainians and others who after the war found themselves outside their supposed home states.
Princippet om at enhver nationalitet var bosat i hver deres egen stat gav anledning til en række fordrivelser og genbosættelser af tyskere, polakker, ukrainere og andre, som efter krigen befandt sig udenfor deres angivelige hjemlande.
