Most of the Prussian provinces of Province of Posen (now Poznan) and of West Prussia which Prussia had annexed in the Partitions of Poland (1772–1795) were ceded to Poland (area 53,800 km², 4,224,000 inhabitants (1931)) without a plebiscite. Most of the Province of Posen had already come under Polish control during the Greater Poland Uprising of 1918–1919.
The Hultschin area of Upper Silesia was transferred to Czechoslovakia (area 316 or 333 km², 49,000 inhabitants) without a plebiscite.
The eastern part of Upper Silesia was assigned to Poland, as in the Upper Silesia plebiscite inhabitants of about 45% of communities voted for this (with general results of 717,122 votes being cast for Germany and 483,514 for Poland).
The area of Eupen-Malmedy was given to Belgium. An opportunity was given to the population to “protest” against the transfer by signing a register, which gathered few signatures. The Vennbahn railway was also transferred to Belgium.
The area of Soldau in East Prussia, an important railway junction on the Warsaw–Danzig route, was transferred to Poland without a plebiscite (area 492 km²).[14]
The northern part of East Prussia known as the “Memelland” or Memel Territory was placed under the control of France and was later annexed by Lithuania.
From the eastern part of West Prussia and the southern part of East Prussia, after the East Prussian plebiscite a small area was ceded to Poland.
The Territory of the Saar Basin was to be under the control of the League of Nations for 15 years, after which a plebiscite between France and Germany, was to decide to which country it would belong. During this time, coal would be sent to France. The region was then called the Saargebiet (German: “Saar Area”) and was formed from southern parts of the German Rhine Province and western parts of the Bavarian Palatinate under the “Saar statute” of the Versailles Treaty of 28. 6. 1919 (Article 45–50).
The strategically important port of Danzig with the delta of the Vistula River on the Baltic Sea was separated from Germany as the Freie Stadt Danzig (Free City of Danzig).

In Africa, Britain and France divided German Kamerun (Cameroons) and Togoland. Belgium gained Ruanda-Urundi in northwestern German East Africa, the United Kingdom obtained by far the greater landmass of this colony, thus gaining the “missing link” in the chain of British possessions stretching from South Africa to Egypt (Cape to Cairo), Portugal received the Kionga Triangle, a sliver of German East Africa. German South West Africa was mandated to the Union of South Africa.[16]
In the Pacific, Japan gained Germany’s islands north of the equator (the Marshall Islands, the Carolines, the Marianas, the Palau Islands) and Kiautschou in China. German Samoa was assigned to New Zealand; German New Guinea, the Bismarck Archipelago and Nauru[17] to Australia as mandatory.[18]
But 1000X?!? I mean the war* did *last longer- nearly six times longer. It did not rage on until the year 2918.
