Silk Road

The Silk Road was not a single road but a shifting web of caravan tracks, oasis towns, and sea lanes that linked East Asia with South Asia, Persia, the Arab world, East Africa, and Europe. The German geographer Ferdinand von Richthofen coined the term Seidenstraße in 1877; the routes themselves long predate the label.

Conventional histories date the opening of sustained East–West exchange to the Han dynasty mission of Zhang Qian to the Western Regions, dispatched by Emperor Wu around 138 BCE. Over the following centuries, Chinese silk, lacquer, and paper moved westward, while horses, glass, wool, precious metals, and new crops moved east. Maritime branches through the Indian Ocean and the Strait of Malacca grew especially important under the Tang, Song, and Yuan dynasties.

The routes also carried ideas and pathogens. Buddhism spread from India into China via Central Asia; Nestorian Christianity, Manichaeism, and later Islam followed merchant networks. Papermaking technology moved west after the 8th century. The Black Death of the mid-14th century is widely thought to have traveled along these same corridors.

Political stability mattered enormously. The Pax Mongolica of the 13th–14th centuries, under the successor states of Genghis Khan, made long-distance travel safer and produced the journeys recorded by Marco Polo (c. 1271–1295) and Ibn Battuta. The network declined as the Mongol order fragmented, the Ming turned inward after the 1430s, and Portuguese maritime routes around Africa offered cheaper alternatives after 1498.

In contemporary diplomacy the term has been revived politically. China's Belt and Road Initiative (BRI), announced by Xi Jinping in 2013, explicitly invokes the Silk Road imagery to frame infrastructure investment across Eurasia, Africa, and Latin America. UNESCO inscribed the "Silk Roads: the Routes Network of Chang'an–Tianshan Corridor" on the World Heritage List in 2014.
