One result of the spread of Buddhism along the Silk Road was displacement and conflict. The Greek Seleucids were exiled to Iran and Central Asia because of a new Iranian dynasty called the Parthians at the beginning of the 2nd century BCE, and as a result the Parthians became the new middle men for trade in a period when the Romans were major customers for silk. Parthian scholars were involved in one of the first ever Buddhist text translations into the Chinese language. Its main trade centre on the Silk Road, the city of Merv, in due course and with the coming of age of Buddhism in China, became a major Buddhist centre by the middle of the 2nd century. Knowledge among people on the silk roads also increased when Emperor Ashoka of the Maurya dynasty (268–239 BCE) converted to Buddhism and raised the religion to official status in his northern Indian empire.
