West Punjab
At Independence there was a Muslim majority in West Punjab with significant Hindu and Sikh minority. Nearly all of these minorities left West Punjab for India, to be replaced by large numbers of Muslims fleeing from the opposite direction. The official language of West Punjab was Urdu but most of the population spoke Punjabi using the Shahmukhi script. The linguist George Abraham Grierson in his multi volume Linguistic Survey of India (1904–1928) considered the various dialects up to then called "Western Punjabi", spoken in North, West, and South of Lahore in what is now Pakistani Punjab, as constituting instead a distinct language from Punjabi. (The local dialect of Lahore is the Majhi dialect of Punjabi, which has long been the basis of standard literary Punjabi.) Grierson proposed to name this putative language "Lahnda", and he dubbed as "Southern Lahnda" the coherent dialect cluster now known as Saraiki spoken in Multan Dera Ghazi Khan and Bahawalpur division and "North Lahnda" now known as Potwari spoken in Rawalpindi division and "Western Lahnda" now known as Hindko spoken in the regions bordering Khyber-Pakhtunkhwa.
Language Movement Day
After the partition of India in 1947, Bengali-speaking people in East Bengal, the non-contiguous eastern part of the Dominion of Pakistan, made up 44 million of the newly formed Dominion of Pakistan's 69 million people. The Dominion of Pakistan's government, civil services, and military, however, were dominated by personnel from the western wing of the Dominion of Pakistan. In 1947, a key resolution at a national education summit in Karachi advocated Urdu as the sole state language, and its exclusive use in the media and in schools. Opposition and protests immediately arose. Students from Dhaka rallied under the leadership of Abul Kashem, the secretary of Tamaddun Majlish, a Bengali Islamic cultural organisation. The meeting stipulated Bengali as an official language of the Dominion of Pakistan and as a medium of education in East Bengal. However, the Pakistan Public Service Commission removed Bengali from the list of approved subjects, as well as from currency notes and stamps. The central education minister Fazlur Rahman made extensive preparations to make Urdu the only state language of the Dominion of Pakistan. Public outrage spread, and a large number of Bengali students met on the University of Dhaka campus on 8 December 1947 to formally demand that Bengali be made an official language. To promote their cause, Bengali students organised processions and rallies in Dhaka.
