Ming treasure voyages in the context of "Ormus"

The Ming dynasty, officially the Great Ming, was an imperial dynasty of China that ruled from 1368 to 1644, following the collapse of the Mongol-led Yuan dynasty. The Ming was the last imperial dynasty of China ruled by the Han people, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the short-lived Shun dynasty), numerous rump regimes ruled by remnants of the Ming imperial family, collectively called the Southern Ming, survived until 1662.

The Ming dynasty's founder, the Hongwu Emperor (r. 1368–1398), attempted to create a society of self-sufficient rural communities ordered in a rigid, immobile system that would guarantee and support a permanent class of soldiers for his dynasty: the empire's standing army exceeded one million troops and the navy's dockyards in Nanjing were the largest in the world. He also took great care breaking the power of the court eunuchs and unrelated magnates, enfeoffing his many sons throughout China and attempting to guide these princes through the Huang-Ming Zuxun, a set of published dynastic instructions. This failed when his teenage successor, the Jianwen Emperor, attempted to curtail his uncle's power, prompting the Jingnan campaign, an uprising that placed the Prince of Yan upon the throne as the Yongle Emperor in 1402. The Yongle Emperor established Yan as a secondary capital and renamed it Beijing, constructed the Forbidden City, and restored the Grand Canal and the primacy of the imperial examinations in official appointments. He rewarded his eunuch supporters and employed them as a counterweight against the Confucian scholar-bureaucrats. One eunuch, Zheng He, led seven enormous voyages of exploration into the Indian Ocean as far as Arabia and the eastern coasts of Africa. Hongwu and Yongle emperors had also expanded the empire's rule into Inner Asia.

Zheng He (also romanized Cheng Ho; 1371–1433/1435) was a Chinese eunuch, admiral and diplomat from the early Ming dynasty, who is often regarded as the greatest admiral in Chinese history. Born into a Muslim family as Ma He, he later adopted the surname Zheng conferred onto him by the Yongle Emperor (r. 1402–1424).

Between 1405 and 1433, Zheng commanded seven treasure voyages across Asia under the commission of the Yongle Emperor and the succeeding Xuande Emperor (r. 1425–1435). According to legend, Zheng's largest ships were almost twice as long as any wooden ship ever recorded, and carried hundreds of sailors on four decks.

The naval history of China dates back thousands of years, with archives existing since the late Spring and Autumn period regarding the Chinese navy and the various ship types employed in wars. The Ming dynasty of China was the leading global maritime power between 1400 and 1433, when Chinese shipbuilders built massive ocean-going junks and the Chinese imperial court launched seven maritime voyages. In modern times, the current People's Republic of China and the Republic of China governments continue to maintain standing navies through the People's Liberation Army Navy and the Republic of China Navy, respectively.

Chen Cheng (simplified Chinese: 陈诚; traditional Chinese: 陳誠; pinyin: Chén Chéng; Wade–Giles: Ch'en Ch'eng; 1365–1457), courtesy name Zilu (子鲁), art name Zhushan (竹山), was a Chinese diplomat of the Ming dynasty, known for his overland journeys into Central Asia. His travels were contemporaneous to the treasure voyages of the admiral Zheng He.
