Ancient Tamil country in the context of "Indo-Roman trade relations"

Indo-Roman trade relations (see also the spice trade and incense road) was trade between the Indian subcontinent and the Roman Empire in Europe and the Mediterranean Sea. Trade through the overland caravan routes via Asia Minor and the Middle East, though at a relative trickle compared to later times, preceded the southern trade route via the Red Sea, which started around the beginning of the Common Era (CE), following the reign of Augustus and his conquest of Egypt in 30 BCE.

The southern route so helped enhance trade between the ancient Roman Empire and the Indian subcontinent, that Roman politicians and historians are on record decrying the loss of silver and gold to buy silk to pamper Roman wives, and the southern route grew to eclipse and then totally supplant the overland trade route. Roman and Greek traders frequented the ancient Tamil country, present day Southern India and Sri Lanka, securing trade with the seafaring Tamil states of the Pandyan, Chola and Chera dynasties and establishing trading settlements which secured trade with the Indian subcontinent by the Greco-Roman world since the time of the Ptolemaic dynasty a few decades before the start of the Common Era and remained long after the fall of the Western Roman Empire.

The Pallava dynasty existed from 275 to 897, ruling a significant portion of the Deccan, also known as Tondaimandalam. The Pallavas played a crucial role in shaping in particular southern Indian history and heritage. The dynasty rose to prominence after the downfall of the Satavahana Empire, whom they had formerly served as feudatories.

The Pallavas became a major southern Indian power during the reign of Mahendravarman I (600–630) and Narasimhavarman I (630–668), and dominated the southern Telugu region and the northern parts of the Tamil region for about 600 years, until the end of the 9th century. Throughout their reign, they remained in constant conflict with both the Chalukyas of Vatapi to the north, and the Tamil kingdoms of Chola and Pandyas to their south. The Pallavas were finally defeated by the Chola ruler Aditya I in the 9th century.
