Communist Party of Upper Silesia
The Communist Party of Upper Silesia was a regional communist organisation in Upper Silesia, active around late 1920. It formed through a merger in November 1920 of the Communist Party of Silesian Land with Silesian branches of the German Communist Party and the Independent Social Democratic Party of Germany (USPD).
Background
Following the end of World War I, Upper Silesia was marked by a complex interplay of national tensions, social discontent, and political radicalism. The collapse of empires and the formation of new states in Central Europe, together with the pronounced economic inequalities in the industrially developed Upper Silesian region, created fertile ground for left-wing movements. In December 1918 a group of German leftists, workers and soldiers’ councils in Bytom formed a group calling itself the Communist Party of Upper Silesia, under the chairmanship of Anton Jadasch. However, from the outset the organisation operated under strong influence from the German Communist Party. In 1919–1920 tensions grew between efforts to advance social and class demands on one side, and competing strong nationalist claims on the other. Communist activists sought to transcend these national divides, promoting class solidarity and rejecting national partisanship, advocating in some organs for the abolition of borders and cooperation among workers regardless of nationality. In September 1920, a faction broke away from the Polish Socialist Party in the Silesian Voivodeship, forming the Communist Party of Silesian Land. In November 1920, this body merged with branches of the KPD and the Independent Social Democratic Party of Germany active in Upper Silesia to formalise the Communist Party of Upper Silesia, with its own central committee yet functioning largely as a regional district of the German party. However, by 1921 the plebiscite over the national affiliation of Upper Silesia, together with the rising strength of nationalist mobilisation, significantly weakened the communists’ position. Many workers who might have sympathised with their class-oriented platform gravitated instead toward nationalist causes. After the partition of the region in 1922, the communist organisations in the Polish-controlled part were absorbed into the Communist Party of Poland, and those in the German part into the KPD.Activities
One of the party's most ambitious goals was the establishment of a Upper Silesian Soviet Republic , modelled after the Soviet system in Russia. This vision was articulated in a manifesto published in November 1920, which called for the creation of a workers' state in Upper Silesia. The party also advocated for the boycott of the 1921 plebiscite, arguing that national borders should not determine the fate of the working class.Despite these efforts, KPGŚ faced significant challenges. The region's strong nationalist sentiments and the presence of competing political ideologies limited the party's influence. Additionally, the Polish government's repression of communist activities further hindered the party's operations. In 1922, following the partition of Upper Silesia, KPGŚ split, with the German section joining the [Communist Party of Germany|Communist Party of Nazi Germany|Germany (KPD)] and the Polish section aligning with the Communist Party of Poland (KPP).
