A tragic episode in the history of the Mings was the capture of the next emperor by the Mongols, who, however, failed to take Peking. It was easier to make a new emperor than to ransom the captive. His brother having been proclaimed, the Tartars sent their captive back, hoping that a war between the brothers would weaken their enemy. Retiring into private life he appeared to renounce his claim; but after the death of his brother he once more occupied the throne. What a theme for a romance! Great Britain was described by a Roman as "almost cut off from the whole world" because it was not accessible by land. China had long been cut off from the Western world because it was not accessible by sea. The way to India was opened by Diaz and Gama in 1498; and the first Portuguese ships appeared at Canton in 1511. Well-treated at first, others came in greater numbers. Their armaments were so formidable as to excite suspicion; and their [Page 137] acts of violence kindled resentment. Under these combined motives a massacre of the foreign traders was perpetrated, and Andrade, a sort of envoy at Peking, was thrown into prison and beheaded. The trading-posts were abolished except at Macao, where the Portuguese obtained a footing by paying an annual rent. After the Portuguese came the Spaniards, who appear to have been satisfied with the Philippine archipelago, rather than provoke a conflict with the Portuguese. The Chinese they had little reason to dread, as the superiority of their arms would have enabled them to seize portions of the seacoast, though not to conquer the Empire as easily as they did the Mexicans and Peruvians. Perhaps, too, they were debarred by the same authority which divided the Western continent between the two Iberian powers. The Chinese becoming too numerous at Manila, the Spaniards slaughtered them without mercy, as if in retaliation for the blood of their cousins, or taking a hint from the policy of China. In 1622 the Dutch endeavoured to open trade with China, but their advances being rejected, doubtless through secret opposition from the Portuguese, they seized the Pescadores, and later established themselves on Formosa, whence they were eventually expelled by Koxinga, a Chinese freebooter.
