This paper concerns the reformulation by British expatriates and the first generation of English-speaking Indian intellectuals of the key ideas of European constitutional liberalism between 1810 and 1835. The central figure is Rammohan Roy, usually seen as a “reformer” of Hinduism. Here Rammohan's thought is set in the context of the Iberian and Latin American constitutional revolutions and the movement for free trade and parliamentary reform in Britain. Rammohan and his coevals created a constitutional history for India that centred on the institution of the panchayat, a local judicial body. While some expatriates and Indian radicals discussed “independence” or “separation” for the country as early as the 1830s, Rammohan himself argued for constitutional limitations on the Company's power and Indian representation in Parliament. Under liberal British government, he believed, an Indian public would emerge, empowered by service on juries and the operations of a free press.
