These were German and Austrian Social Democratic party branches in areas transferred to Poland after the Silesian Uprisings.
The party, although geographically limited to Upper Silesia, intended to organize German workers throughout the Polish republic.
[3] On August 21, 1922, DSPP formed an electoral bloc together with the Independent Socialist Labour Party (NSPP).
The NSPP leader, Bolesław Drobner, decided to withdraw their candidate lists and break the agreement with DSPP in protest of Kowoll and Buchwald joining the 'German Club' in the Silesian Sejm.
The merger was however only nominal, in reality DSPP and DAP continued to exist as separate parties until October 1929.
