Pakistan
More than sixty languages are spoken in Pakistan, including a number of provincial languages. Urdu—the "lingua franca" and a symbol of Muslim identity and national unity—is the national language understood by over 75% of Pakistanis. It is the main medium of communication in the country but the primary language of only 8% of Pakistan's population. Urdu and English are the official languages of Pakistan, with English primarily used in official business and government, and in legal contracts; the local variety is known as Pakistani English. The Punjabi language, the most common in Pakistan and the first language of 44.2% of Pakistan's population, is mostly spoken in the Punjab. Saraiki, mainly spoken in South Punjab and Hindko, is predominant in the Hazara region of Khyber Pakhtunkhwa. Pashto is the provincial language of Khyber Pakhtunkhwa and is well understood in Sindh and Balochistan. The Sindhi language is commonly spoken in Sindh while the Balochi language is dominant in Balochistan. Brahui, a Dravidian language, is spoken by the Brahui people who live in Balochistan. Gujarati community leaders in Pakistan claim that there are 3 million Gujarati speakers in Karachi. Marwari, a Rajasthani language, is also spoken in parts of Sindh. Various languages such as Shina, Balti, and Burushaski are spoken in Gilgit-Baltistan, whilst languages such as Pahari, Gojri, and Kashmiri are spoken by many in Azad Kashmir.
History of East Pakistan
One of the most divisive issues confronting Pakistan in its infancy was the question of what the official language of the new state was to be. Mohammad Ali Jinnah yielded to the demands of refugees from the Indian states of Bihar and Uttar Pradesh, who insisted that Urdu be Pakistan's official language. Speakers of the languages of West Pakistan (Punjabi, Sindhi, Pushtu, and Baluchi) were upset that their languages were given second-class status. In East Pakistan, the dissatisfaction quickly turned to violence. The Bengalis of East Pakistan constituted a majority (an estimated 54%) of Pakistan's entire population. Their language, Bengali, like Urdu, belongs to the Indo-Aryan language family, but the two languages have different scripts and literary traditions.
