Futteh Ali, the old Shah of Persia, died in 1834, and was succeeded by his grandson Prince Mahomed Meerza, a young man who inherited much of the ambition of his gallant father Abbas Meerza. His especial aspiration, industriously stimulated by his Russian advisers, urged him to the enterprise of conquering the independent principality of Herat, on the western border of Afghanistan. Herat was the only remnant of Afghan territory that still remained to a member of the legitimate royal house. Its ruler was Shah Kamran, son of that Mahmoud Shah who, after ousting his brother Shah Soojah from the throne of Cabul, had himself been driven from that elevation, and had retired to the minor principality of Herat. The young Shah of Persia was not destitute of justification for his designs on Herat. That this was so was frankly admitted by Mr Ellis, the British envoy to his Court, who wrote to his Government that the Shah had fair claim to the sovereignty of Afghanistan as far as Ghuznee, and that Kamran's conduct in occupying part of the Persian province of Seistan had given the Shah 'a full justification for commencing hostilities against Herat.' The serious phase of the situation for England and India was that Russian influence was behind Persia in this hostile action against Herat. Mr Ellis pointed out that in the then existing state of relations between Persia and Russia, the progress of the former in Afghanistan was tantamount to the advancement of the latter. But unfortunately there remained valid an article in the treaty of 1814 to the effect that, in case of war between the Afghans and the Persians, the English Government should not interfere with either party unless when called on by both to mediate. In vain did Ellis and his successor M'Neill remonstrate with the Persian monarch against the Herat expedition. An appeal to St Petersburg, on the part of Great Britain, produced merely an evasive reply. How diplomatic disquietude had become intensified may be inferred from this, that whereas in April 1836 Ellis wrote of Persia as a Russian first parallel of attack against India, Lord Auckland, then Governor-General of India, directed M'Neill, in the early part of 1837, to urge the Shah to abandon his enterprise, on the ground that he (the Governor-General) 'must view with umbrage and displeasure schemes of interference and conquest on our western frontier.'
