The conquest of China being firmly established, Kanghe was now able to turn his attention to his own country, which he visited, attended by his whole court and an army of sixty thousand men. He also sent ambassadors to the frontiers, to settle with the Russians the limits of the two empires--nor did he confine himself to the possessions already obtained, but under pretence of assisting the Mongols, many of whom had become tributary to the Mantchou monarchs, previously to the conquest of China, he extended his possessions northeastward, into the country of the Soungarians, whom, as well as some of the tribes of Turkestan and of Thibet, he entirely subdued. After a long and glorious reign of sixty-one years, Kanghe died in 1722, in the sixty-ninth year of his age, leaving the succession to his fourth son; but his fourteenth son taking advantage of his elder brother’s absence from the capital, seized on the billet of succession, and having changed the number four to fourteen, assumed the throne and the Kwo-haou of Yung-ching. Yung-ching’s reign is chiefly remarkable for his persecution of the Roman Catholic missionaries, most of whom were sent out of the country. He showed neither the literary nor the military talents displayed by his father, Kanghe, and by his son and successor Keentung; but he was attentive to the business of the government, and to the people. In the fourth year of his reign, the treaty of peace, now existing between the Russian and Chinese empires, was ratified. By this instrument, the Russians, among other privileges, are permitted to have an academy and church, with an archimandrite, three inferior priests, and six scholars, at Pekin. The time fixed for their stay there is ten years. Yung-ching reigned thirteen years, and died in the year 1735, leaving the succession to his fourth son who took the Kwohaou or title of Keentung. Keentung’s reign produced many literary works, or rather compilations; it is remarkable for some brilliant conquests in Eastern Tartary or Turkestan and Thibet. The Soungarians having revolted, he entirely annihilated them as a nation, and peopled their country with the inhabitants of more peaceful districts and with Chinese.
