Connecting Two Worlds: Trade, Faith, and the End of an Era

Though separated by an ocean and a continent, the trading empires of the medieval Sahel and the kingdoms of medieval Southeast Asia built their power on a strikingly similar logic: control of a route or a node of trade mattered more than control of a fixed, clearly bounded territory. Ghana's "gatekeeper" strategy — taxing the gold and salt that passed through its hands without ever mining or producing either itself — has a close cousin in the Southeast Asian "mandala" or "galactic polity" model, in which a center of power, such as Srivijaya or Malacca at the Strait of Malacca, projected diminishing influence outward over a network of loyal ports and vassals rather than ruling a single unified territory with fixed borders in the modern, European sense.
