Punjab
The major language spoken in the Punjab is Punjabi. In the Indian Punjab this is written in the Gurmukhi script. Pakistan uses the Shahmukhi script, that is closer to Urdu script. Hindi, written in the Devanagri script, is used widely in the Indian states of Himanchal Pradesh and Haryana. Several dialects of Punjabi are spoken in the different regions. The Majhi dialect is considered to be textbook Punjabi and is shared by both countries.
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.
