Generalplan Ost
The Nazi plan to ethnically cleanse the territories occupied by Germany in Eastern Europe during World War II, was called the Generalplan Ost (GPO). Germanisation began with the classification of people suitable as defined on the Nazi Volksliste. About 1.7 million Poles were deemed Germanizable, including between one and two hundred thousand children who were taken from their parents. For the rest, expulsion was carried out.
