Roman trade with India started around 1 CE following the reign of Augustus and his conquest of Egypt, theretofore India's biggest trade partner in the West.

The trade started by Eudoxus of Cyzicus in 130 BCE kept increasing, and according to Strabo (II.5.12), by the time of Augustus up to 120 ships were setting sail every year from Myos Hormos to India. So much gold was used for this trade, and apparently recycled by the Kushans for their own coinage.



Roman trade diaspora frequented the ancient Tamil country (present day Southern India), securing trade with the seafaring Tamil kingdoms of the Chola, Pandyan and Chera dynasties and establishing trading settlements which remained long after the fall of the Western Roman empire. They also outlasted Byzantium's loss of the Egypt and the Red Sea ports (ca. 639-645 CE) under the pressure of Jihad and Islam, which had been used to secure trade with India by the Greco-Roman world since the time of the Ptolemaic dynasty a few decades before the start of the Common Era
