• Aurang was a Persian term for a warehouse – a place where goods are collected before being sold. The term also refers to a workshop.
• The term banian is the Anglicised form of the Sanskrit and Bangla word banik (merchant). In Anglo-Indian society and among the natives too a banian was one who was engaged by an individual western merchant or a firm to work for them as a broker, interpreter and agent.
• Under the ryotwari settlement system, the government recognized mirasidars as the sole proprietors of land, dismissing tenants’ rights completely.
