The Silk Road, a network of Eurasian trade routes active from the 2nd century BCE to the mid-15th century, spanned over 6,400 km and played a crucial role in connecting the East and West. Facilitating economic, cultural, political, and religious exchanges, the Silk Road, or more accurately Silk Routes as some historians argue, comprised a complex web of land and sea routes. These routes linked various regions including Central, East, South, Southeast, and West Asia, along with East Africa and Southern Europe. The term "Silk Road" itself originated in the late 19th century.
