Margaret went on to reside at the Meissen court, where she had a significant impact on her husband's government: in 1432 she had all Jews expelled from the former margravate. In the Saxon Fratricidal War over the 1445 Division of Altenburg, she helped to reconcile her husband with his rebellious brother, Landgrave William III of Thuringia. Margaret received her own coinage ("Margarethengroschen") and a mint in the Saxon burgraviate of Colditz, which caused further trouble with her brother-in-law William. Nevertheless, the minting privilege was finally confirmed by Emperor Frederick III in a 1463 deed.
