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.
Punjabi Language Movement
The Punjabi Language Movement (PLM) is a linguistic movement in Punjab, Pakistan aimed at reviving the Punjabi language, art, culture and literature in Pakistan. The Punjabi people constitute the largest ethnic group in Pakistan though Urdu is the national language and unlike Indian Punjab (where reading/writing Punjabi language is compulsory at every level from 2008 alongside a special Punjabi University at Patiala), Punjabi itself does not have an official status. 
The PLM's ideologies are based on Punjabi nationalism.
