News of the imposture soon reached Moscow, and Boris instantly denounced Dimitri as an impostor, and sent emissaries to endeavour to secure his arrest. In this, however, they were unsuccessful; and the false Dimitri not only succeeded in raising a considerable force in Poland, but also in convincing the great mass of the Russian population that he really was the son of Ivan. In 1604 he appeared on the Russian frontier at the head of a small but efficient force, and overthrew the army which Boris had sent against him. His success was supposed by the ignorant peasantry to be entirely due to the interposition of Providence, which was working on the side of the injured prince, and Dimitri was careful to foster the delusion that his cause was specially favoured by heaven. He treated his prisoners with the greatest humanity, and ordered his followers to refrain from excesses, and to cultivate the goodwill of the people. The result was that his ranks rapidly increased, while those of the czar diminished. Even foreign governments began to view the offender with favour; and at last Boris, devoured by remorse for the crimes which he had committed, and by chagrin at the evil fate which had fallen upon him, lost his reason and poisoned himself. The chief nobles assembled when the death of the czar was made known, and proclaimed his son Feodor emperor in his stead; but the lad's reign was very brief. The greater part of the army and the people declared in favour of Dimitri, and the citizens of Moscow having invited him to assume the reins of power, Dimitri made a triumphal entry into the capital, and was crowned with great pomp. At first he ruled prudently, and, had he continued as he began, might have retained his strangely acquired throne. But after a time he gave himself up to the gratification of his own wild passions, and lost the popularity which he really had succeeded in gaining. He disgusted the Russians by appointing numerous Poles, who had swelled his train, to the highest posts in the empire, to the exclusion of meritorious officers, who not only deserved well of their country, but also had claims upon himself for services which they had rendered. These Polish officers misconducted themselves sadly, and the people murmured sore. The czar, too, made no secret of his attachment to the Catholic faith; and while by so doing he irritated the clergy, he provoked the boyards by his haughty patronage, and disgusted the common people by his cruelty and lewdness. At last the murmurs grew so loud and threatening, that some means had to be devised to quiet the popular discontent, and Dimitri had recourse to a strange stratagem. The widow of Ivan, who had long before been immured in a convent by the orders of Boris, and had been kept there by his successor, was released from her confinement, and was induced publicly to acknowledge Dimitri as her son. The widowed empress knew full well that her life depended
