The story is interesting. This is how the Jana Sangh's official history, published by the BJP a few years ago, explains it.

An RSS rally in Delhi in December 1947 drew a large crowd and also attracted Hindu princes, businessmen and leaders of other Hindu organisations. This popularity was something that alarmed the Congress, especially Nehru, according to the RSS.

The assassination of Gandhi on 30 January 1948 gave the Congress the opportunity to move. It decided to ban the RSS on 2 February, three days after Gandhi’s murder.

RSS chief Golwalkar had sensed that the RSS would get into trouble once the details of Gandhi’s assassination were out. He acted immediately. On the day of the killing, 30 January 1948, he sent telegrams to RSS branches to suspend operations for 13 days. The same day, he also telegrammed Nehru, Patel and Devdas Gandhi with a message of condolence: ‘Shocked at this cruel fatal attack and tragic loss of greatest personality.’

The next day, he again wrote to Nehru, expressing his shock and referring to Godse as ‘some thoughtless perverted soul’ who had ‘committed the heinous act of putting a sudden and ghastly end to the life of poojya Mahatmaji by the bullet’. He called the killing unpardonable and an act of treason.

That day he wrote also to Patel: ‘My heart is wrung with extreme agony. It is difficult to find words to condemn the person who committed this crime…’

The government notification declaring the RSS unlawful said:

‘Undesirable and even dangerous activities have been carried on by members of the Sangh (who) have indulged in acts of violence involving arson, robbery, dacoity, and murder and have collected illicit arms and ammunitions. They have been found circulating leaflets exhorting people to resort to terrorist methods to collect firearms… rendering it incumbent on the government to deal with the Sangh in its corporate capacity,’ the government concluded

Golwalkar was arrested on 3 February, along with 20,000 swayamsevaks. The RSS says it was shocked that no political party and no political leader spoke up for it or stood in its defence.

The ban remained for a little under a year and a half. It was lifted after the RSS was asked to produce a constitution. This was written up and submitted. The ban was lifted on 11 July 1949.

Immediately following this, the RSS began to debate entering politics in the pages of its house organ, the Organiser

It published articles from RSS workers, including K.R. Malkani, who wrote that the Sangh ‘must take part in politics not only to protect itself’ but also ‘to stop un-Bharatiya and anti-Bharatiya politics’ and to ‘advance the cause of Bharatiyata through state machinery’. For these reasons, the Sangh must ‘continue as an ashram for the national cultural education of the entire citizenry, but it must develop a political wing for the more effective and early achievement of its ideals’.

Malkani said the new party ‘will be revivalist of ancient values as it will be futuristic in its targets’ and it would be told ‘not to depend on foreign values, attitude and manners’ and that ‘the principle of this re-organisation in Hindustan can only be Hindutva’.

An RSS worker from the Arya Samaj, Balraj Madhok, wrote that the Sangh ‘must give the lead to the country in regard to the political and economic problems of the country’ because this was ‘vital to the very existence of the Sangh itself’.

Mookerjee in his statement to Parliament on 19 April 1950 said that he had ‘played a very large part in creating public opinion in favour of a Partition of Bengal’. As part of this, he ‘gave assurances to the Hindus of East Bengal (later, Bangladesh) stating that if they suffered at the hands of the future Pakistan government… free India would not remain an idle spectator’.

As we read and assess what is going on around us in the India of 2025, it is instructive to do this through the lens of 75 years ago and the events that led to the formation of the BJP as we know it.
