A 'Banian' was an Indian agent, broker, or native factor who worked for European traders, especially the English East India Company, acting as a middleman in trade and financial transactions. A 'Mirasidar' in South India was a landowner who had hereditary rights to the land and was recognized as the primary revenue payer to the state, often under systems like the Ryotwari settlement. The term 'Aurang' typically referred to a division or a large sub-division of territory, or sometimes a warehouse, rather than a specific officer in charge of the treasury.
