The anarchy in Samarra allowed a number of provinces to fall into the hands of rebels, while provincial governors were free to act in an independent manner in the territories assigned to them. The effective loss of provinces, in turn, resulted in a decrease in taxation revenues received by the central government, further exacerbating the crisis in the capital and crippling the government's ability to effectively respond to challenges against its authority. This continuing instability greatly facilitated the initial success of the Zanj revolt, as the government proved incapable of committing sufficient troops and resources to subdue the rebels.
