The Malkana are a Muslim ethnic group found in the states of Uttar Pradesh and Bihar of India.
Arya Samaj Swami Shraddhanand's Shuddhi movement aimed at converting them to Hinduism, which led to Abdul Rashid, who shot him dead in Delhi.
[3][1] Many Muslim leaders attempted to counter this leading to religious tensions in Shahabad, Gaya and Munger.
The shuddhi campaign among the Malkanas, was launched in early 1923 and led by the Arya Samaj under Pandit Madan Mohan Malaviya.
This re-conversion campaign reached its peak by the end of 1927, by which time some 1,63,000 Malkana Muslims are said to have been brought into the Hindu fold.
