[1] Chinese name variations of prominent personages stem from the practice of acquiring new names, such as with the acquisition of new positions (e.g., on becoming an emperor); or with the establishment of new dynasties; and so on. Moreover, the existence of two forms of romanization of Chinese names, Wade-Giles and the newer Pinyin does not help matters. For the present account, the following name/spelling variations (based mainly but not only on Encyclopedia Brittanica) are relevant: Genghis Khan (c. 1162–1227): also spelled Ching-gis, Chingis, Jenghiz, and so on. Also known as Temüjin (Temuchin). He established the dynasty that his grandson, Kublai Khan, later proclaimed as the Yuan dynasty (1206–1368—also known as the Mongol dynasty) and of which Kublai Khan would be the first emperor. Kublai Khan (1215–94): also spelled Khubilai, or Kubla Hung-wu (1328–1398): also spelled Hongwu—also known as Kao-ti, T’ai Tsu, and Chu Yuan-chang (Zhu Yuanzhang). Cheng Ho (1371–1435): also spelled Zheng He; and who was also known as Ma San-pao, Ma Ho, San Bao. His family claimed that they were descendants of an early Mongol governor of Yunnan and a descendant of King Muhammed of Bukhara. The family name Ma came from the Chinese rendition of Muhammed. Yung-lo (1360–1424; third emperor of the Ming dynasty from 1402–1424): also spelled Yonglo—also known as Ch'eng Tsu, T'ai Tsung, Wen Ti, and Chu Ti [Zhu Di].
[2] To fully appreciate the might of the naval power these expeditions represented for the time period, consider this comparison by Finlay (1995): The Portuguese Army that attacked Morocco and captured Ceuta in 1415 numbered about 12,000; the fall of the Muslim province of Granada in 1492 had been achieved with 20,000 men, while the French invasion of Italy in 1494 under Charles VIII had involved about 28,000 soldiers. The usual number that made up a field army in the early sixteenth-century in Europe ranged roughly from 25,000 to 30,000 men—vide, Philip II’s Spanish Armada, for example, that was sent to invade England in 1588, it had aboard a total of about 29,500 soldiers. As for the size of the European ships, they were absolutely no match for the Chinese ones: the largest of Vasco da Gama’s ships, for example, could only displace 300 tons at the most and carry 170 men (versus 600 men for Cheng Ho’s 3,000-ton ships). Even in the case of the Spanish Armada, the sizes of their ships were wanting: the largest had a capacity of only 1,294 tons. Clearly then, as Finlay, concludes, the Ming Indian Ocean expeditions “were the largest long-distance enterprises before the modern age, dwarfing anything that the most powerful European state could produce” (p. 95).
