This volume explores human migration, communication, and cross-cultural exchange on the Silk Road, a complex network of trade routes spanning the Eurasian continent and beyond. It covers thousands of years of human history, from the 3rd millennium BCE to the early 2nd millennium CE. Consolidating archaeological discoveries, historical analyses, and linguistic studies in one comprehensive volume, it brings to light diverse perspectives from scholars who have lived and worked across this vast region, many of which are published here in English for the first time.
