The gathering was convened by the Shiromani Akali Dal (Amritsar), Dal Khalsa, Panch Pardhani Jatha and the Jagtar Singh Hawara Committee. Earlier in the day, the groups held a joint conference near Gurdwara Santokhsar Sahib. The conference was addressed by SAD (Amritsar) chief Simranjit Singh Mann and former militant leader Daljit Singh Bittu, after which participants marched to the Akal Takht. Representatives of the jailed Khadoor Sahib MP Amritpal Singh-led Akali Dal (Waris Punjab De) attended the event, though the party's senior leadership stayed away.
