In 1025, Rajendra Chola launched one of medieval India's most extraordinary overseas military campaigns. From South India, a Chola fleet crossed the Bay of Bengal to strike Kadaram and other major ports of the Srivijaya maritime empire in Southeast Asia. But this was more than a naval raid: it was a story of imperial ambition, trade, merchant networks, diplomacy, navigation, and power. Drawing on the dramatic world of Rajendra Chola, this book follows the campaign from Tamil Nadu to the Malay Peninsula and explores how the Cholas projected power across the sea—and how the merchant networks connected to that victory outlived the empire itself. The manuscript centers on Rajendra Chola, Kadaram, the Chola Empire, Srivijaya, the 1025 campaign, and the wider relationship between warfare and Indian Ocean trade.
