Punjab, Pakistan
The major and native language spoken in the Punjab is Punjabi (which is written in a Shahmukhi script in Pakistan) and Punjabis comprise the largest ethnic group in country. Punjabi is the provincial language of Punjab, but is not given any official recognition in the Constitution of Pakistan at the national level.
Shahmukhi alphabet
The Shahmukhi alphabet was first used by the Sufi poets of the Punjab; it became the conventional writing style for the Muslim populace of the Pakistani province of Punjab following the independence of Pakistan in 1947, while the largely Hindu and Sikh modern-day state of Punjab, India adopted the Gurmukhi script to record the Punjabi language.
