The recent return to terrestrial forms of connectivity over long distances, not least in the wake of China’s inauguration of the ‘Belt and Road Initiative’, has renewed interest in the Silk Roads. This chapter explains that the web of routes which connected various parts of Afro-Eurasia persisted throughout the rise of trans-oceanic networks after circa 1500, at which time north-south routes from the Eurasian continental interior into the Indian subcontinent and the Indian Ocean world became more prominent. The history of this remarkable survival is one of the themes of this book. To introduce these themes, this chapter sketches the contours of those states and empires—Mughal, Sikh, Afghan, Safavid, Uzbek, British and Russian—whose fates were tied up with the history of Indo-central Asian caravan trade.
