Language is the most important aspect of culture. It is the dominant feature in determining nationality or ethnicity. It is the binding force that unites a people, and makes them distinct from others.
Language represents a people's heritage and identity.
However, the imposition of Urdu as the national language of Pakistan has been disastrous to the country. Urdu language evolved during the declining period of Muslim rule in South Asia. Turkic and Arabic languages were also popular, Turkic language being the mother-tongue of many among the ruling elite, and Arabic language learnt for religious or scholarly purposes. The base of most South Asian Muslim empires was in north India, particularly in Delhi and surrounding areas. Other regions continued their native languages such as Punjabi, Sindhi, Pashto, Kashmiri, Seraiki, Baluchi, etc. having nothing to do with Urdu, while Persian was the official language throughout the Muslim empire.
