The Jallianwala Bagh massacre took place on 13 April 1919. The Acting Brigadier-General Reginald Dyer ordered troops of the British Indian Army to fire into the unarmed crowd. A total number of 379 people died and over 1,000 people injured.
The Sikhs never agreed with the issue of Kashmir which was fixed as per the treaty of Lahore. That is why the treaty of Bhairowal was signed in December 1846. Rani Jindan was removed as the regent and Rs. 1.5 lakh was given to her and replaced by a council consisting of 8 Sikh members.
