The caste system in India caused much social rest during the 1920s.
 The criminal-by-birth laws against targeted castes was enforced until the mid-20th century, with an expansion of criminal castes list in west and south India through the 1900s to 1930s
 Ramnarayan Rawat, a professor of History and specialising in social exclusion in the Indian subcontinent, states that the criminal-by-birth castes under this Act included initially Ahirs, Gurjars and Jats, but its enforcement expanded by the late 19th century to include most Shudras and untouchables, such as Chamars, as well as Sannyasis and hill tribes
