A dramatic painting depicting the Jallianwala Bagh massacre has been unveiled at Mancheser Museum on the centenary of the atrocity.

The painting by the Singh twins, Rabindra and Amrit, is titled Jallianwala: Repression and Retribution. It measures 2.5 metres by 3 metres and is executed in the Moghul miniature style.

The painting will remain on display until October 2 at Manchester Museum.

In the painting, there is an image of Brigadier General Reginald Dyer on the right, while on the left there is one of the social and political reformer Annie Besant carrying a placard bearing the image of the nationalist leader Bal Gangadhar Tilak.

The twins said they had set Amritsar in the wider context of British history by also including “depictions of the 1770 Boston Massacre and Manchester’s Peterloo Massacre of 1819 which position Jallianwala as part of an ongoing history of State violence against civilian protests in Britain and its colonies”.

The Boston Massacre, in which British soldiers killed several people after a mob harassed them, is considered to have “laid the foundation of American independence”.

The Peterloo Massacre took place when cavalry charged into a crowd that was demanding parliamentary representation reforms.
