How did the Chera dynasty develop trade with western Asia?

The Chera dynasty, centered on the Malabar Coast, developed trade with western Asia by leveraging the region's natural resources, particularly spices, which were highly sought after by the Greeks and Romans (collectively known as Yavana in early Indian literature).12

This maritime commerce was significantly bolstered by the discovery of seasonal monsoon winds, which allowed ships to navigate directly across the Arabian Sea to western Asian ports. The Chera region became a vital hub for this international exchange, with Sangam literature documenting the presence and prosperity of Yavana merchants in the area.32

The economic importance of this trade was such that it became a central activity for southern Indian states, with goods like pepper, pearls, and ivory being exported in exchange for Roman gold, wine, and various metals. The relationship was not always peaceful; historical accounts, such as those concerning the Chera chief Nedunjeral Adan, note that Chera rulers occasionally attacked Yavana ships and held traders for ransom, reflecting the complex and high-stakes nature of this ancient maritime network.231
