Majha
The partition split the Punjab Province (British India) into the two states of West Punjab (Punjab, Pakistan) and East Punjab. However, the historic Majha region is arguably still the same as before since the partition does not change the previous history of Punjab, therefore does not change the geography of the Majha region of the historic Punjab region.
History of Pakistan
Intense communal rioting in the Punjab forced the governments of India and Pakistan to agree to a forced population exchange of Muslim and Hindu/Sikh minorities living in Punjab. After this population exchange only a few thousand low-caste Hindus remained in Pakistan's side of Punjab and only a tiny Muslim population remained in the town of Malerkotla in India's part of Punjab. Political scientist Ishtiaq Ahmed says that although Muslims started the violence in Punjab, by the end of 1947 more Muslims had been killed by Hindus and Sikhs in East Punjab than the number of Hindus and Sikhs who had been killed by Muslims in West Punjab.
