On 13 April 1923, during a procession by local Congress volunteers in Nagpur commemorating the Jallianwala Bagh massacre, the "Swaraj" flag with the spinning wheel, designed by Pingali Venkayya, was hoisted. This event resulted in a confrontation between the Congressmen and the police, after which five people were imprisoned. Over a hundred other protesters continued the flag procession after a meeting. Subsequently, on the first of May, Jamnalal Bajaj, the secretary of the Nagpur Congress Committee, started the "Flag Satyagraha", gaining national attention and marking a significant point in the flag movement. The "satyagraha", promoted nationally by the Congress, started creating cracks within the organisation in which the Gandhians were highly enthused while the other group, the "Swarajists", called it inconsequential.
