This article argues that from circa 1845–1857, British colonial officials and administrators, abetted by Protestant missionaries and some so-called ‘native Christians’, attempted to replace Brahmanical regulation of everyday life with what I am calling ‘governance by conscience’ in British India. It uses the 1851 legal ruling in Narayen Ramchundur versus Luxmeebae, hailed by some for bringing ‘liberty of conscience’ and condemned by others as a wanton violation of Hindu personal law, to elucidate the connections between the Caste Disabilities Removal Act of 1850 (Act XXI) and education. My analysis highlights the centrality of Brahman wives and gender to debates about conscience, caste, property, and Christian conversion. During the violent summer of 1857, some condemned the Act and its use in deciding the case of Narayen Ramchundur versus Luxmeebae as provocation for the traumatic disorders then threatening to dismantle Britain's Indian empire.
