Hindi in Pakistan
Before the partition of British India, Hindi was spoken in the region forming Pakistan by the Hindus and Sikhs residing there. It was taught across school and university levels, mainly in Punjab and Sindh. After the partition, most of these communities left for India; prominent Hindi writers with origins in Pakistan include Bhisham Sahni, Shailendra, Hullad Moradabadi, Uday Bhanu Hans, Narendra Mohan and others. Conversely, some first-generation Pakistanis who migrated from India during Pakistan's independence in 1947 were familiar with Hindi and the Devanagari script.
