Empires and the Silk Road
The Sogdians in Central Asia (Afghanistan and Uzbekistan) began to sell horses to the Persian Empire to their west. And they sold horses to the Chinese emperors to their east, and south into India. This was the beginning of the Silk Road.
Sogdians and China
Soon the Sogdians added other things to sell. They sold cattle, and they sold peaches and knotted woolen carpets. Under the Han Dynasty, as China developed a strong empire, Chinese people started to sell more silk and pottery to the Sogdians, who sold it again to their west.
Silk began to travel all the way across Asia, as far as the new Roman Empire. In return, the Romans traded gold, furs, wool and linen cloth, and glass cups and bowls east to the Sogdians. Some Roman glass even reached China and Japan.

India and Rome
As East-West trade along the Silk Road became more important, people began to look for other, less expensive routes. The Ptolemies in Egypt figured out how to use ocean currents to sail to India and back.
The Romans, who were often fighting with the Parthian Empire to their east, used this route through Egypt and Arabia to India. Chinese traders also found ways to sail from China to India, avoiding the Sogdians. India became an important place for trade, as much as Afghanistan. India sold steel, and cotton cloth, medicines, and sugar.
Vikings and Russia
About 500 AD, the Sogdians and their neighbors in Central Asia figured out new things to trade – even more valuable and tradable than horses and cattle. Like the people of India, they began to make steel, and to produce sugar. In Egypt, the invention of knitting speeded up production of clothing, and traders sold knitted stockings and gloves all over.
The fall of the western part of the Roman Empire in the 400s AD left much of Europe too poor to do much trading. Further north, though, the Vikings figured out a new route through Russia to the Sogdians, and eagerly traded furs and amber and enslaved people for the good Central Asian steel. To the south, the Islamic Empire continued trading through Mecca to India.
When the Arabs conquered North Africa in the 600s AD, they expanded trade south across the Sahara and all along the coast of East Africa too. So most people in Africa could also buy steel, sugar, cotton cloth from India, and silk from China.
The end of the Silk Road
But by the end of the Middle Ages, people were building better ships. They were learning how to use a magnetic compass to sail out of sight of land.
That allowed them to use the oceans for more and more of their trade, and slowly they stopped using the Silk Road.
