The Global Tapestry
From Song China's civil-service bureaucracy to the Islamic Golden Age, the empires of the Americas, the trading kingdoms of Africa, and feudal Europe, a survey of the world's major societies on the eve of intensified global connection.
States & Societies, c. 1200–1450
Before the world's regions were tightly bound by ocean-spanning empires, each major society developed distinctive ways of organizing power, belief, and trade. In East Asia, the Song Dynasty ruled through a Confucian scholar-bureaucracy and civil-service exam, powering an economic revolution built on Champa rice, the Grand Canal, and proto-industrial iron and steel.
Across Dar al-Islam, political unity fractured, the Abbasids gave way to Seljuk Turks, Mamluks, and the Delhi Sultanate, but a shared Islamic culture flourished, preserving Greek learning in the House of Wisdom and driving advances in math, medicine, and astronomy. In the Americas, the Maya, Aztec, and Inca built sophisticated theocratic states without contact with the Old World.
Meanwhile, trans-Saharan and Indian Ocean trade enriched the African kingdoms of Mali and the Swahili city-states, and in Europe, decentralized feudalism, the manorial economy, and Church authority defined a fragmenting medieval order slowly reawakening to long-distance trade.
