I was reading about Mao’s early guerrilla campaigns in Hunan and such, and the incorrect Li Lisen and Chen Duxiu lines. Despite there being massive losses taken during both the reconcilitory and adventurist periods, Mao never split from the CPC and that seemed to work pretty well.

Conversely, Rosa Luxemburg and Karl Liebknect [along with many other members] didn’t split from the SPD to form the KPD until the start of the German Revolution, and arguably this contributed to their downfall.

Obviously the SPD is an extreme example, but still. Is there a good way to tell when a split should occur, and the best way to do it?
