Rashtriya Swayamsevak Sangh   is an Indian right-wing,Hindu nationalist volunteer paramilitary organisation. It is the progenitor and leader of a large body of organisations called the Sangh Parivar (Hindi for "Sangh family"), which has developed a presence in all facets of Indian society and includes the Bharatiya Janata Party, the ruling political party under Narendra Modi, the 14th prime minister of India.[8] Mohan Bhagwat has served as the Sarsanghchalak of the RSS since March 2009.

A unique phenomenon in the history of Bharat in the twentieth century is the birth and unceasing growth of Rashtriya Swayamsevak Sangh (RSS). The Sangh’s sphere of influence has been spreading far and wide, not only inside Bharat but also abroad, like the radiance of a many splendored diamond. Sangh-inspired institutions and movements today form a strong presence in social, cultural, educational, labour, developmental, political and other fields of nationalist endeavour. Sangh initiated movements - be they social-reformist or anti-secessionist - evoke ready response and approbation from the common multitudes as well as from vast numbers of elite of different shades. It has increasingly been recognized that the Sangh is not a mere reaction to one or another social or political aberration. It represents a corpus of thought and action firmly rooted in genuine nationalism and in the age old tradition of this country.

No other movement or institution has attracted such vast numbers of adherents, several thousands of them making social work their life’s mission, whose character and integrity are not doubted even by their most virulent critics.

As a movement for national reconstruction totally nurtured by the people, Sangh has no parallel in Bharat or elsewhere. The growth of the Sangh - as a movement for assertion of Bharat’s national identity - acquires added significance when we remember that the birth of the Sangh was preceded by mental, cultural and economic onslaught by alien rulers for long decades.

There could be only one explanation for the continuing march of the Sangh from strength to strength: The emotive response of the millions to the vision of Bharat’s national glory, based on the noblest values constituting the cultural and spiritual legacy of the land and collectively called ‘Dharma’, comprising faith in the oneness of the human race, the underlying unity of all religious traditions, the basic divinity of the human being, complementarity and inter-relatedness of all forms of creation both animate and inanimate, and the primacy of spiritual experience. That the mission of the Sangh is in tune with a millennia old heritage itself carries an irresistible appeal.
