The Bronze Age in Khorasan and Transoxania
The establishment of settled agricultural societies in the Bronze Age allowed social and cultural developments to occur. Population growth across this period also led to expansion into new geographical areas, as illustrated by archaeological excavations across Central Asia. The emergence of metallurgy and the production of tools and craft objects in metal went hand-in-hand with the need to procure raw materials from other areas, thus promoting the earliest lines of trade across Asia and encouraging social and cultural interaction between regions.
