Areas that were transferred from Germany to other states after World War II?

First of all, this is East Prussia. It was divided between the USSR and Poland (about 1/3 of the territory went to the USSR, the other 2/3 to Poland). Germany also lost land along the Oder. These are Silesia and Pomerania (Eastern and Lower). They were included in Poland as compensation for the fact that Western Belarus and Ukraine became part of the USSR.

Alsace and Lorraine were also rejected. However, they were French before the war and without it. Germany simply gave up the right to them.
