In 1956, B. R. Ambedkar publicly converted to Buddhism raising questions about his turn from constitutionalism to religion. The answer lies in Buddhism itself. In the late colonial era, the struggle to produce an appropriate Buddhism for a nation-in-the-making reveals a secret history foundational to modern India. Thinkers, activists, reformers, pilgrims, and monks from around South, Southeast and East Asia discussed universalism, nationalism, modernity, democracy, and caste radicalism and advocated an Indian return to Buddhism and the Buddha. This book traces this genealogy through the Buddhist itineraries and political projects of figures like Anagarika Dharmapala, Swami Vivekananda, Rabindranath Tagore, Jawaharlal Nehru, Vinayak D. Savarkar, Rahul Sankrityayan and Ambedkar, to reveal how Buddhism emerged as democracy's dhamma, the religion of democracy.

The book examines the works of Akshay Kumar Dutta (1820–1886), who can be seen as ideologically inhabiting the cusp between religion and rationalism – the two most crucial avenues of debate and discussion in the public sphere in nineteenth-century Bengal. While nineteenth-century Bengal has been an important discourse within South Asian history, major figures of reform such as Rammohun Roy, Debendranath Tagore, Iswarchandra Vidyasagar, or Keshub Chunder Sen have generally been the focus. The book attempts to rescue Dutta from the clutches of academic amnesia, and to locate him as one of the foundational figures of intellectual refashioning among the common albeit educated public in nineteenth-century Bengal.
