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
When Pakistan was created in 1947, although Punjabi was the majority language in West Pakistan and Bengali the majority in East Pakistan and Pakistan as whole, English and Urdu were chosen as the national languages. The selection of Urdu was due to its association with South Asian Muslim nationalism and because the leaders of the new nation wanted a unifying national language instead of promoting one ethnic group's language over another. Broadcasting in Punjabi language by Pakistan Broadcasting Corporation decreased on TV and radio after 1947. Article 251 of the Constitution of Pakistan declares that these two languages would be the only official languages at the national level, while provincial governments would be allowed to make provisions for the use of other languages. However, in the 1950s the constitution was amended to include the Bengali language. Eventually, Punjabi was granted status as a provincial language in Punjab Province, while the Sindhi language was given official status in 1972 after 1972 Language violence in Sindh.
