Keshub Chandra Sen was a Hindu philosopher and social reformer who attempted to incorporate Christian theology within the framework of Hindu thought. Born a Hindu in the Bengal Presidency of British India, he became a member of the Brahmo Samaj in 1857 but established his own breakaway "Bharatvarshiya Brahmo Samaj" in 1866 while the Brahmo Samaj remained under the leadership of Debendranath Tagore. In 1878, his followers abandoned him after the underage child marriage of his daughter which exposed his campaign against child marriage as hollow. Later in his life he came under the influence of Ramakrishna and founded a syncretic "New Dispensation" inspired by Christianity, Vaishnav bhakti, and other Hindu practices.

Maharaja Nripendra Narayan was the Maharaja of the princely state of Cooch Bihar, India, from 1863 to 1911.
