Pandit Din Dayalu Sharma established the Bharat Dharma Mahamandal in 1887 in Haridwar to propagate Sanatan Dharma and Hindu culture. It was an All-Indian organisation of the orthodox educated Hindus, which stood for a defence of traditional Hinduism against the teachings of Arya Samajists, the Ramakrishna Mission, and the Theosophists. Pandit Madan Mohan Malaviya was a prominent leader in the Bharat Dharma Mahamandal.
In 1887, Pandit Din Dayalu Sharma organised a meeting of people who followed Sanatan Dharma (in Haridwar) and founded Bharat Dharma Mahamandal to propagate the Basic values of Hinduism. Scholars from all over the country were present. Madan Mohan Malaviya was also part of this group.
The objective of the Bharat Dharma Mahamandal was to bring together all leaders of the orthodox Hindu community and to work together to preserve the Sanatan Dharma.
Other organisations formed to defend orthodox Hinduism were Sanatan Dharma Sabha (1895), the Dharma Maha Parishad in South India, and Dharma Mahamandali in Bengal. In 1902, these organisations merged to form the single organisation of Bharat Dharma Mahamandala, with headquarters at Varanasi. This organisation sought to introduce proper management of Hindu religious institutions, open Hindu educational institutions, etc.
