Under the constitution of 1973 which language was declared as the National language of Pakistan

The 1973 Constitution declares Urdu as Pakistan's national language promoting unity. Punjabi Bengali and Sindhi are regional languages. Urdu is used in education media and official documents. The constitution allows provincial languages alongside Urdu. This provision reflects Pakistan's linguistic diversity and efforts to balance national identity with regional cultures. Understanding this is essential for studies in Pakistani governance and cultural policy.
