Punjabi language
Doabi is spoken in both the Indian Punjab as well as parts of Pakistan Punjab owing to post-1947 migration of Muslim populace from East Punjab. The word "Do Aabi" means "the land between two rivers" and this dialect was historically spoken between the rivers of the Beas and the Sutlej in the region called Doaba. Regions it is presently spoken includes the Jalandhar, Hoshiarpur and Kapurthala districts in Indian Punjab, specifically in the areas known as the Dona and Manjki, as well as the Toba Tek Singh and Faisalabad districts in Pakistan Punjab where the dialect is known as Faisalabadi Punjabi.
History of Haryana
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, under which 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. 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.
