Punjabi language
In India, Punjabi is one of the 22 scheduled languages of India. It is the first official language of the Indian State of Punjab. Punjabi also has second language official status in Delhi along with Urdu, and in Haryana. 
In Pakistan, no regional ethnic language has been granted official status at the national level, and as such Punjabi is not an official language at the national level, even though it is the most spoken language in Pakistan after Urdu, the national language of Pakistan. It is, however, the official provincial language of Punjab, Pakistan, the second largest and the most populous province of Pakistan as well as in Islamabad Capital Territory. The only two official national languages in Pakistan are Urdu and English, which are considered the lingua francas of Pakistan.The Majhi (ماجھی ਮਾਝੀ) dialect spoken around Amritsar and Lahore is Punjabi's prestige dialect. Majhi is spoken in the heart of Punjab in the region of Majha, which spans Lahore, Amritsar, Gurdaspur, Kasur, Tarn Taran, Faisalabad, Nankana Sahib, Pathankot, Okara, Pakpattan, Sahiwal, Narowal, Sheikhupura, Sialkot, Chiniot, Gujranwala and Gujrat and in Mandi Bahauddin(97’/.) districts.
East Pakistan Renaissance Society
The Muslim League and most other advocates of Pakistan had demanded a single state of Pakistan consisting of the British Indian provinces of Punjab, Khyber Pakhtunkhwa (then Northwest Frontier Province), Sindh, Balochistan and Bengal, and sought the Urdu language to be the only official language and "lingua franca" of Muslims. However, the East Pakistan Renaissance Society not only argued that Muslims were a separate nation from Hindus, it also advocated that the Bengali Muslims were distinct from the Muslims of other parts of India, on an ethnic, cultural and geographical basis. Unlike religion, the society argued that ethnicity and cultural differences cannot cross geographic boundaries. The society and its supporters in the Bengal Muslim League asserted that Bengali Muslims should constitute an independent state, as an "Eastern Pakistan" rather than part of a single state of Pakistan. The society asserted the importance of the Bengali culture and language, which many advocates of Pakistan criticised as being "Hinduised" and "Sanskritised."
