How Ebert was able to prevent a revolution
1. Maintained the support of the army by not reforming it or creating a new force
2. Kept the support of industrialists, who negotiated with trade unions the Central Working Association Agreement, which gave workers an eight-hour day and established workers' councils in large companies
3. The working class was divided between the communists (KPD), who wanted a Soviet style of government, and supporters of the SPD, who wanted a parliamentary system
