The Great Coalition was a coalition formed in 1923 by the 4 main pro-democratic parties within the Reichstag: -The SPD, a moderate socialist party -The Centre Party, a centrist Catholic party -The DDP, a liberalist middle-class party -The DVP, a centre-right party led by Gustav Stresemann
It was Gustav Stresemann who re-united these parties to work together in the time of crisis and to eliminate hyperinflation. The Great Coalition worked to fight challenges from the extreme right and left wings.
The Great Coalition called off the workers strike to oppose the French invasion of the Ruhr (which convinced the SPD to leave the coalition), convinced the French to leave the Ruhr and subsequently introduced the Rentenmark to successfully fight hyperinflation.
