While revolutionaries dismantled ruling government and party organizations all over the country, because power seizures lacked centralized leadership, it was no longer clear who truly believed in Mao's revolutionary vision and who was opportunistically exploiting the chaos for their own gain. The formation of rival revolutionary groups, some manifestations of long-established local feuds, led to factional violent struggles across the country. Tension grew between mass organizations and the military as well. In response, Lin Biao issued a directive for the army to aid the radicals. At the same time, the army took control of some provinces and locales that were deemed incapable of sorting out their own power transitions.
