The economic history of eastern India during the eighteenth and early nineteenth centuries reveals the dynamic and multifaceted role played by regional trade networks and commercial communities in shaping the economic landscape of the region. Bihar, situated along the fertile Gangetic plains and strategically connected through an extensive system of riverine as well as overland routes, emerged as a significant center of both internal and external trade during the late Mughal and early colonial periods. The geographical advantages of the region, including the presence of major rivers such as the Ganga and its tributaries, facilitated the movement of goods, merchants, and capital, thereby integrating Bihar with wider commercial networks across northern and eastern India. Between 1707 and 1857, a period marked by the gradual decline of the Mughal Empire and the subsequent expansion of British colonial influence, Bihar experienced notable changes in its economic structure. During this time, commercial activities expanded considerably, market towns and urban centers grew in number and importance, and a variety of merchant groups including banias, mahajans, bankers, and itinerant traders actively participated in trade, credit, and financial transactions. The region became well known for the production and trade of several important commodities such as saltpetre, opium, indigo, textiles, food grains, and other agricultural products, which were circulated through an interconnected network of local markets, periodic bazaars, and large regional fairs. These markets not only facilitated the exchange of goods but also served as important nodes linking rural production centers with urban commercial hubs and long-distance trade routes. This article examines the structure and functioning of economic networks and commercial activities in pre-colonial Bihar by focusing on key aspects such as trade routes, major commodities, merchant communities, systems of credit and finance, and the institutional role of markets and fairs in promoting regional commerce. It argues that the economy of Bihar during this period was far from stagnant; rather, it was characterized by vibrant regional trade networks, active commercial groups, and indigenous financial institutions that played a crucial role in connecting agrarian production with expanding urban markets and broader interregional trade circuits across the Indian subcontinent.
