Punjabi Language Movement

The Punjabi Language Movement (Punjabi: پنجابی زبان تحریک, romanized: Pañjābī zabān tahrīk, pronounced [pəɲˈd͡ʒaːbːi zəˈbaːn təɦˈɾik]; abbreviated as PLM) is a socio-political movement in Punjab, Pakistan, advocating the recognition of the Punjabi language, as well as culture and literature, in Pakistan to allow its use in government affairs, education, and media. Today, the Punjabi people constitute the largest ethnic group in the country, though Urdu was given status as the sole national language of the country, following independence.
