Whose defeat ended the anti-Polish campaign that began with the idea to unify all the German and possibly also Germanic-speaking peoples in a single nation-state known as "Großdeutschland".?
Expulsion of Poles by Germany The Expulsion of Poles by Germany was a prolonged anti-Polish campaign of ethnic cleansing by violent and terror-inspiring means lasting nearly half a century. It began with the concept of Pan-Germanism developed in the early 19th century and culminated in the racial policy of Nazi Germany that asserted the superiority of the Aryan race. The removal of Poles by Germany stemmed from historic ideas of expansionist nationalism. It was implemented at different levels and different stages by successive German governments. It ended with the defeat of Nazi Germany in 1945.
Territorial evolution of Germany The territorial changes of Germany include all changes in the borders and territory of Germany from its formation in 1871 to the present. Modern Germany was formed in 1871 when Otto von Bismarck unified most of the German states, with the notable exception of Austria, into the German Empire. After the First World War Germany lost about 10% of its territory to its neighbours and the Weimar Republic was formed. This republic included territories to the east of today's German borders.
