Upper Silesia Plebiscite
Consequently, to the end of World War I in 1918 various proposals emerged defining the division of Upper Silesia. At the Paris Peace Conference, 1919, Paris Peace Conference a commission for Polish affairs was created to prepare proposals for Polish borders. In their first two proposals (of 27 March 1919 and of 7 May 1919) most of the future province was ceded, together with the region of Province of Silesia#Administration, Oppeln, to Poland. Yet that was not accepted by the ''Big Four'', and following David Lloyd George's suggestion, the Upper Silesia plebiscite, plebiscite was organized. Before it took place on 20 March 1921, two Silesian Insurrections instigated by Poles, Polish inhabitants of the area were organized. After the referendum, in which Poland had 41% of the votes, a plan of division was created that divided Upper Silesia. Following this, the Third Silesian Uprising took place. The Inter-Allied Commission on Upper Silesia, headed by the French general Henri Le Rond suggested a new plan for division of the area, which was prepared by an ambassadors commission in Paris on 20 October 1921. The division - which became effective by 20 June 1922 - still created a situation in which some rural territories that voted mostly for Poland were granted to Germany and some urban territories with a German majority were granted to Poland. The Polish Sejm decided that the easternmost Upper Silesian areas should become an autonomous area within Poland organised as the Silesian Voivodeship (1920–1939), Silesian Voivodeship and with Silesian Parliament as a constituency and Silesian Voivodeship Council as the executive body. The part of Silesia awarded to Poland was by far the best-developed and richest region of the newly formed state, producing most of Poland's industrial output. Consequently, to the division in 1922, the German-Polish Accord on East Silesia (Geneva Convention) was concluded on 15 May 1922 which dealt with the constitutional and legal future of Upper Silesia as it has partly become Second Polish Republic, Polish territory.Inter-War Silesia
Nazi Germany
East Upper Silesia was annexed by Nazi Germany along Polish areas annexed by Nazi Germany, with other Polish areas following the Invasion of Poland (1939), invasion of Poland in 1939, which triggered the outbreak of World War II. Until 1941, the region was administered as ''Regierungsbezirk Kattowitz'', the easternmost government region of the Silesia Province. From 1941 to 1945, it was part of the Upper Silesia Province. Under Nazi rule, Upper Silesia included the cities of Bytom, Beuthen, Gliwice, Gleiwitz, Zabrze, Hindenburg in Oberschlesien, Katowice, Kattowitz, and Chorzów, Königshütte. It also contained the rural districts (''Landkreis'') of Będzin, Bendsburg, Beuthen-Tarnowskie Góry, Tarnowitz, Bielsko, Bielitz, Kattowitz, Chrzanów, Krenau, Olkusz, Ilkenau, Pszczyna, Pless, Rybnik, Żywiec, Saybusch, Cieszyn, Teschen, and Toszek-Gleiwitz. In the spring of 1945, the region was occupied by the Red Army after the Silesian Offensives defeated the Wehrmacht there.Present day
After the war, East Upper Silesia was restored to Poland. Poland also received West Upper Silesia and most of Lower Silesia as part of the Recovered Territories. Today, the region is roughly represented by the Silesian Voivodeship.See also
