The establishment of Naujawan Bharat Sabha took place in Lahore in 1925-26. Its founder members were Bhagat Singh, Bhagwati Charan Vohra, Sukhdev, Principal Chabil Dass, Yashpal, etc.

Main Objects: The main objects of this organisation were as follow:

• Spread of the spirit of fraternity among the people.
• Stress on simple life.
• To develop the spirit of sacrifice.
• To promote feelings of patriotism among the people.
• To propagate revolutionary ideas among the masses.

Membership: All the men and women between 18 years and 35 years could join this association. Only those persons could become its members who had faith in its programme. Many women and men of Punjab extended co-operation to this association. Durga Devi Vohra, Sushil Mohan, Amar Kaur, Parvati Devi and Leelavati were members of this association.

Activities: The members of this association were active at the time of visit of Simon Commission. In Punjab, under the leadership of Lala Lajpat Rai, the revolutionaries took out a procession against Simon Commission in Lahore. The English government lathi-charged the procession. In this Lala Lajpat Rai was badly injured. He died on 17th November, 1928. During this period, all the revolutionaries set up their central organisation which was named as Hindustan Socialist Republic Association. Members of Naujawan Bharat Sabha also started working in collaboration with this association.

Assembly Bomb Case. On 8th April, 1929 Bhagat Singh and Batukeshwar threw a bomb in the Central Legislative Assembly and surrendered.

The police arrested Sukhdev and Rajguru, two other great revolutionaries. These revolutionaries were implicated in the second Lahore Conspiracy case and tried.

On 23rd March, 1931 Bhagat Singh, Sukhdev and Rajguru were hanged to death in Borstal Jail at Lahore. The pieces of their dead bodies were put in bags and were thrown half-burnt near Hussaniwala in Ferozepur on the bank of river Sutlej. A memorial has been built at Hussaniwala in the memory of these great martyrs. It is true that Sardar Bhagat Singh, the gem of the Naujawan Bharat Sabha, set such an example of martyrdom of which the coming generations will always feel proud of.
