What territories did the Allies lost or gain in WW1 and WW2?

You left out Japan as a member of the Allies in World War 1. They fought the Germans in China and the Pacific, with their navy involved in many combined operations with the Royal Australian Navy. They also fought some land battles, such as Tsingtao. The Union of Soviet Socialist Republics (Bolshevik Russia) in WW2 was also a member of the Allies, following the German invasion of 1941. They were the ones who took over Berlin and forced the Germans out of the war to start with, and faced the most brutal battles of World War 2 (no other theater of war claimed as many lives as the Eastern Front of World War 2.)

After WW1 Poland I think gained control over a large amount of Prussia. Japan gained control of a few of the German colonies in the Pacific and in China. France and Britain gained control of some of the German interests in Africa and the Middle East.

After WW2 France, Britain and the USA gained control over West Germany and West Austria, as well as all of West Europe. The USSR gained control over East Germany and East Austria, as well as all of East Europe (except for Greece and Turkey.) The USA also gained control over Japan. France reinstated it's control over Indochina and Madagascar. Britain reinstated it's control over Malaya and Serawak.
