The Socialists' Bloc (Polish: Blok Socjalistów) was a political coalition of left-wing parties oriented around the Polish Socialist Party.
It operated in the Silesian Voivodeship during the 1930 Polish parliamentary election[3] and in the November 1930 Silesian Parliament election,[4] where it lost two seats.
[5] The Bloc united the Polish and German left in Silesia, although the two had already loosely cooperated beforehand.
