Overland routes refer to the various land-based pathways that facilitated trade and cultural exchange between different regions, particularly during the period from 1200 to 1450. These routes played a crucial role in connecting distant areas, allowing merchants and travelers to transport goods such as silk, spices, and other valuable commodities across vast distances. The overland routes were integral to the establishment of trade networks that spanned continents, shaping economic and cultural interactions across Eurasia.
