The power of the satraps was practically absolute, and a thoroughly disloyal Satrap could even go so far as to seize some favourable opportunity to detach his province from the empire and make himself an independent sovereign. The King was, indeed, accustomed to make a journey of inspection every year into one or other of his provinces, but in each province such visits were of rare occurrence, and a Satrap who wished to seek his own advantage, instead of studying the interests of the King and of the empire, had every opportunity of doing so. ‘The empire is large,’ he might well say to himself, ‘and the King is far away.’ With a view to checking such tendencies on the part of the Satraps, the Persian nobles were trained in habits of implicit obedience and subjection to the sovereign, and were kept in constant fear of being ruined by some report of treason or misgovernment on their part which should reach the ears of the King. Upon the smallest suspicion, and without any sort of trial, a man who was accused of plotting treason against the King might be removed from his post, and either openly or secretly put to death. A story is told of Darius I., who was one of the best of the Great Kings, that once, when he was about to engage in an expedition against the Scythians, a Persian noble prostrated himself before him, and craved as a boon that of his three sons he might be allowed to keep one at home with him. The King answered that he should keep them all at home, and gave command to put them to death immediately. In a similar manner the people were crushed by severe and cruel laws, just as wild animals are cowed by ill-treatment and want of food. As conquered nations they were not expected to have any attachment to the King, or any interest in the welfare of the empire, and although now and again services rendered to the King would be rewarded by overwhelming favours, yet the means chiefly relied upon for securing good behaviour was the certainty that every offence would meet with prompt and barbarous punishment. Not only criminals, but even persons merely suspected of having committed crimes, were put to death in the most horrible manner. Some were crushed between stones, others were torn limb from limb, and others, again, suffered painful imprisonment in troughs. For merely trifling offences they were cruelly mutilated.
