The document discusses Poland's resettlements that took place after 1945 following World War 2 and the Yalta Conference. Key points include: - Poland lost territory to the Soviet Union and gained other lands from Germany, resulting in the large-scale resettlement of millions of Poles and Germans. - Compulsory resettlements of Poles from eastern territories formerly part of Poland took place from 1944-1946 after these lands were lost to the Soviet Union per the Yalta agreements. - For ordinary people, the resettlements meant losing all their property suddenly and being displaced to unknown areas with only what they could carry. Descendants of those displaced still live in the places they resettled
