There have been various insights and models as to how the administration of the Persian Empire operated. A common assumption made by researchers is that the satraps would frequently act independently from the king's wishes in the administration. Further, if the king was aware of their actions, he often ignored them. A particular historical example is the satrap Pissouthnes' involvement in the Samian revolt from Athens. This is one of the multiple conundrums in Greek-Persian relation.
