Indo-Roman trade and relations

Roman trade in the Indian Subcontinent (see also the spice trade and incense road) and Indian trade in Europe and the mediterranean through the overland caravan routes via Asia Minor and the Middle East, though at a relative trickle compared to later times, antedated the southern trade route via the Red Sea and monsoons which started around the beginning of the Common Era (CE) following the reign of Augustus and his conquest of Egypt in 30 BCE.
