There is no country, however abject its inhabitants may appear, where the most daring and ambitious can venture to usurp the supreme power without first obtaining a hold on public opinion; we cannot have a stronger proof of this fact, as applicable to Persia, than what we find in the conduct of Nadir upon this memorable occasion. Though that chief had revived the military spirit of his country, and roused a nation sunk in sloth and luxury to great and successful exertion, yet neither this success, the imbecility of Shah Tamasp, nor a reliance upon his own fame and strength could induce him to take the last step of usurpation, until he had, by his arts, excited in the minds of his countrymen that complete contempt for the reigning sovereign, and that pride in his glory, which were likely to make his elevation appear more the accomplishment of their wishes than of his ambition. At the same time that Nadir published the proclamation which has been mentioned, he addressed letters to all the military chiefs of the country. In that to the Governor of Fars, which has been preserved, he informs him of the great success he has had against the Afghans and of the conquest of Herat. He then proceeds to state the astonishment and indignation with which he has learnt the particulars of the treaty concluded with Turkey. "You will no doubt," he observes, "be rejoiced to hear that, as it was to be hoped from the goodness of God, this peace with the Turks is not likely to endure; and you may rest in expectation of my approach; for, by the blessing of the Most High, I will advance immediately, with an army elated with success, skilled in sieges, numerous as emmets, valiant as lions, and combining with the vigor of youth the prudence of age. Let the cup-bearer," he exclaims, quoting from a popular poet, "tell our enemy, the worshipper of fire, to cover his head with dust, for the water that had departed is returned into its channel." He concludes this letter by threatening, with excommunication and destruction, all Shiahs, or, in other words, all Persians who are adverse to the renewal of hostilities. "Those Shiahs," he observes, "who are backward on this great occasion, and are reconciled to this shameful peace, shall be expelled from the faithful sect and forever counted among its enemies. To slaughter them will be meritorious; to permit their existence impious."
