The All-India Hindu Mahasabha was founded in 1915, at a session held at Hardwar during the Kumbh Mela.

Background:

• In the early 20th century, several provincial Hindu Sabhas were formed, especially in Punjab (the Punjab Hindu Sabha, 1909), to protect the interests of Hindus.
• The founding of the Muslim League (1906) and the introduction of separate electorates for Muslims (1909) encouraged the formation of Hindu organisations.

About the Hindu Mahasabha:

• The provincial Hindu Sabhas were brought together into an all-India organisation, the Sarvadeshak Hindu Sabha, in 1915, which was later renamed the All-India Hindu Mahasabha.
• Its first session at Hardwar was presided over by the Maharaja of Kasimbazar, Manindra Chandra Nandy.
• Its leaders included Madan Mohan Malaviya, Lala Lajpat Rai and Swami Shraddhanand.

Its aims:

• To protect and promote the interests of Hindus.
• To work for the unity of Hindus, the removal of untouchability, and social reform.
• To encourage the "Shuddhi" (reconversion) and "Sangathan" (organisation) of Hindus.

In the 1920s and 1930s:

• After the communal riots of the 1920s, the Hindu Mahasabha became more active.
• D. Savarkar became its President in 1937, and remained so until 1943; under him, the Mahasabha promoted the idea of "Hindutva".
• Shyama Prasad Mookerjee was another leading figure.

Its role in the freedom struggle:

• The Hindu Mahasabha did not take part in the Quit India Movement.
• It opposed the partition of India and the demand for Pakistan.
