Maria Grollmuß

Accordingly, she wrote various articles for Rhein-Mainische Volkszeitung, a newspaper close to the left wing of Zentrumspartei,[3] and for the magazine of the Catholic youth movement "Quickborn" called Die Schildgenossen, initiated by Romano Guardini.

She was excluded from KPD due to her opposition to forming separate communist trade unions, so she joined the Kommunistischen Partei-Opposition, whose minority wing she belonged to together with Paul Frölich and Jacob Walcher.

In close cooperation with the Arbeitskreis Revolutionärer Sozialisten, she supported political prisoners, transported illegal literature and helped endangered comrades to escape to Czechoslovakia.

She operated from the village of Radibor in Upper Lusatia, her father's place of birth.

She was in contact with resistance groups of the SPD, KPD, SAPD and the Austrian socialist Otto Bauer.

The Nazi government offered her freedom and cancer therapy if she agreed to spy for them in the Sorbian resistance movement once having served her term.
