The Silk Roads

The Silk Roads, after falling into disuse, were revived by the 8th and 9th centuries and were vital for interregional trade in the 14th and 15th centuries.
Demand for luxury goods increased in Europe and Africa.
Chinese, Persian, and Indian artisans and merchants expanded their production of textiles and porcelain for export.
Caravans made travel safer, and China developed paper money to manage trade.

The Crusades: Lords and knights brought back fabrics and spices from the East, stimulating European interest.
Resilience of Trade Routes: Despite the Ottoman Turks' inroads, the Silk Roads and the Mediterranean/Indian Ocean sea routes remained operational.
Mutual Demand: China wanted Europe's gold and silver; Europe desired silk, tea, and rhubarb from China.
Rise of New Empires: The collapse of classical civilizations like Rome and Han led to a decline, but Arab merchants from the Abbasid Empire revived the Silk Roads in the 8th and 9th centuries.
Tang China: It offered the compass, paper, and gunpowder; exported porcelain, tea, and silk; and imported cotton, precious stones, pomegranates, dates, horses, and grapes.
Mongol Empire: The Mongol Empire had the most significant impact. In 1258, the Mongols conquered the Abbasid Caliphate, and in the 14th century, they controlled China. The Mongols unified the Silk Roads under one authority, respected merchants, and enforced laws. They improved roads, punished bandits, and established new trade channels.

Caravans: Traveling in groups was safer.
Camel Saddles: Improved designs increased load capacity.
Chinese Naval Technology:

Bill of Exchange: A document promising payment of a set amount on a set date.
Hanseatic League: A commercial alliance in northern Germany and Scandinavia that controlled trade in the North and Baltic Seas.

The growing demand for luxury goods from Afro-Eurasia, China, Persia, and India increased the supply of those goods through expanded production.
Craftworkers increased their production of goods such as silk, other textiles, and porcelain for export.
Increased demand led to iron and steel manufacturing expansion in China, motivating its proto-industrialization.
