The Indian Workers' Association (IWA) is a political organisation in Great Britain which consists of Indian immigrants to Britain and their descendants. IWA branches are organised in some major cities such as Birmingham and London. As one of the oldest and most active groups of immigrants, the organisation has been working in the fields of politics, race relations, industrial relations and social welfare, as well as many cultural issues. At the forefront of the struggle within trade unions, it has campaigned tirelessly against racism and on civil liberties issues.

Udham Singh was an Indian revolutionary belonging to Ghadar Party and HSRA, best known for assassinating Michael O'Dwyer, the former lieutenant governor of the Punjab in India, on 13 March 1940. The assassination was done in revenge for the Jallianwala Bagh massacre in Amritsar in 1919, for which O'Dwyer was responsible and of which Singh himself was a survivor. Singh was subsequently tried and convicted of murder and hanged in July 1940. While in custody, he used the name 'Ram Mohammad Singh Azad', which represents the three major religions in India and his anti-colonial sentiment.
