Roman trade with India in the context of "Pudukottai"

The spice trade involved historical civilizations in Asia, Northeast Africa and Europe. Spices, such as cinnamon, cassia, cardamom, ginger, pepper, nutmeg, star anise, clove, and turmeric, were known and used in antiquity and traded in the Eastern World. These spices found their way into the Near East before the beginning of the Christian era, with fantastic tales hiding their true sources.

The maritime aspect of the trade was dominated by the Austronesian peoples in Southeast Asia, namely the ancient Indonesian sailors who established routes from Southeast Asia to Sri Lanka and India (and later China) by 1500 BC. These goods were then transported by land toward the Mediterranean and the Greco-Roman world via the incense route and the Roman–India routes by Indian and Persian traders. The Austronesian maritime trade lanes later expanded into the Middle East and eastern Africa by the 1st millennium AD, resulting in the Austronesian colonization of Madagascar.

Indian maritime history begins during the 3rd millennium BCE when inhabitants of the Indus-Saraswati Valley civilisation initiated maritime trading contact with Mesopotamia. India's long coastline, which occurred due to the protrusion of India's Deccan Plateau, helped it to make new trade relations with the Europeans, especially the Greeks, and the length of its coastline on the Indian Ocean is partly a reason why it's known as that.

As per Vedic records, Indian traders and merchants traded with the far east and Arabia. During the Maurya Empire (3rd century BCE), there was a definite "naval department" to supervise the ships and trade. At the end of 1st century BCE, Indian products reached the Romans during the rule of Augustus, and the Roman historian Strabo mentions an increase in Roman trade with India following the Roman annexation of Egypt. As trade between India and the Greco-Roman world increased, spices became the main import from India to the Western world, bypassing silk and other commodities. Indians were present in Alexandria, while Christian and Jewish settlers from Rome continued to live in India long after the fall of the Roman Empire, which resulted in Rome's loss of the Red Sea ports, previously used to secure trade with India by the Greco-Roman world since the Ptolemaic dynasty. The Indian commercial connection with Southeast Asia proved vital to the merchants of Arabia and Persia during the 7th–8th century. A study published in 2013 found that some 11 percent of Australian Aboriginal DNA is of Indian origin and suggests these immigrants arrived about 4,000 years ago, possibly at the same time dingoes first arrived in Australia.
