The new regime was headed by Ernst Niekisch, a left-wing Social Democrat and teacher from Augsburg in Swabia. His ascendancy to power in Bavaria signaled a clear move away from a process of democratization compatible with Western-style parliamentary democracy. He was a supporter of National Bolshevism, a political movement that rejected the internationalism of Bolshevism but, other than that, believed in Bolshevism.
