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.
Punjabi Suba movement
Hindi language movement of Punjab in the Hindi-speaking areas of Punjab started on 30 April 1957 and lasted till 27 December 1957, which paved the way for the demand for the formation of Haryana as a separate state for the Hindi speaking people of the united Punjab province. At the same time Punjab also had Punjabi suba & Punjabi language movement. Punjabi and gurmukhi were made official state language and script respectively, which was also made mandatory in schools of the whole of post-independence united Punjab. People of Hindi speaking areas of Punjab resisted this imposition in masses. Punjab government retaliated by mass arrests and imprisonments, some of arrested activists were tortured in the prison. Sumer Singh of Naya Bans in Rohtak district gave his life for this cause during this movement.
