Yermolov became governor-general in 1816, and soon afterwards the Chechens and Daghestanians began to give the Russians serious trouble. Then the clergy raised a national movement in Imereti, in which Guri and Apkhazi joined, and in Mingreli, hitherto faithful, the Dadian's brother revolted. All these efforts to shake off the Russian yoke were, of course, fruitless, and they ended in 1822 with the capture of Zakatali from the Lesghians. Then the Cherkesses (Circassians) broke into rebellion, and in 1826 Persia again declared war against Russia and marched 60,000 men into Georgia. Aided by the Lesghians and the Kakhetians, under Alexander, son of Irakli, they were at first successful, but the tide turned, and Erivan, Tavriz, and other places saw Russia victorious. Paskevich succeeded Yermolov in 1827, and the peace of Turkmenchai having been concluded with Persia, war was declared against Turkey. The Russians took Kars, Poti, Akhalkalaki, Akhaltsikhe, Bayazid from the Turks, and in 1829 the belligerents signed the treaty of Adrianople. In 1830 Kasi-mullah began his revolt, and brought about a general rising among the Mahometan peoples of the Caucasus. Baron Rosen, who took the command of the army in 1831, captured Gimri, and Kasi-mullah was killed. Golovin (1837), Neidhart (1842), and Prince Vorontsov (1844-1854) enjoyed comparative peace, and were able to turn their attention to the internal condition of the country. Prince Vorontsov especially deserves credit for his honest and painstaking efforts to ameliorate the economic situation of Georgia, and it flatters our national pride to remember that that statesman was English by birth and education, if not by blood. The pacification of Daghestan did not, as was expected, follow the death of Kasi-mullah. A greater prophet and warrior arose to take the place of the vanquished hero of Gimri. Shamil, after carrying on a guerilla warfare for about ten years, raised the whole of the Eastern Caucasus in 1843, and continued to inflict a series of crushing defeats on the Russian generals who were sent to oppose him. The declaration of war with Turkey in 1853 raised the hopes of the Lesghians, but the utter incapacity of the Turkish leaders in Armenia prevented the realization of those hopes. Everybody is familiar with the incidents of Shamil's career down to the capture at Gunib in 1859; but it seems to me that too little attention has been devoted to the remarkable religious system which inspired the Murids to their marvellous deeds of valour. It is surely a noteworthy fact that the mysticism of the Sufis should have been found to be compatible with a purely militant faith like Islam.
