The Silk Road appeared during the first century BCE, and Afghanistan flourished with trade, with routes to China, India, Persia and north to the cities of Bukhara, Samarkand and Khiva in present-day Uzbekistan. Goods and ideas were exchanged at this center point, such as Chinese silk, Persian silver and Roman gold, while the region of present Afghanistan was mining and trading lapis lazuli stones mainly from the Badakhshan region.
