Punjabi language
In India, Punjabi is one of the 22 scheduled languages of India. It is the first official language of the Indian State of Punjab. Punjabi also has second language official status in Delhi along with Urdu, and in Haryana. 
In Pakistan, no regional ethnic language has been granted official status at the national level, and as such Punjabi is not an official language at the national level, even though it is the most spoken language in Pakistan after Urdu, the national language of Pakistan. It is, however, the official provincial language of Punjab, Pakistan, the second largest and the most populous province of Pakistan as well as in Islamabad Capital Territory. The only two official national languages in Pakistan are Urdu and English, which are considered the lingua francas of Pakistan.The Majhi (ماجھی ਮਾਝੀ) dialect spoken around Amritsar and Lahore is Punjabi's prestige dialect. Majhi is spoken in the heart of Punjab in the region of Majha, which spans Lahore, Amritsar, Gurdaspur, Kasur, Tarn Taran, Faisalabad, Nankana Sahib, Pathankot, Okara, Pakpattan, Sahiwal, Narowal, Sheikhupura, Sialkot, Chiniot, Gujranwala and Gujrat and in Mandi Bahauddin(97’/.) districts.
History of Lahore
For the British, Punjab was a frontier province, because Lahore had boundaries with Afghanistan. Therefore, the Punjabis, unlike the Bengalis and the Sindhis, were not allowed to use their mother tongue as an official language. The British first introduced Urdu as an official language in Punjab, including Lahore, allegedly due to a fear of Punjabi nationalism. During the rule of British colonial government, the Punjabi Muslims started reclaiming and rebuilding of the Muslim monuments occupied, damaged and destroyed by the Sikhs during their heavy handed rule in the Punjab region.
Under British rule (1849–1947), colonial architecture in Lahore combined Mughal, Gothic and Victorian styles. The General Post Office (GPO) and YMCA buildings in Lahore commemorated the golden jubilee of Queen Victoria, an event marked by the construction of clock towers and monuments all over India. Other important British buildings included the High Court, the Government College University, the museums, the National College of Arts, Montgomery Hall, Tollinton Market, the University of the Punjab (Old Campus) and the Provincial Assembly.
Under British rule, Sir Ganga Ram (sometimes referred to as the father of modern Lahore) designed and built the General Post Office, Lahore Museum, Aitchison College, Mayo School of Arts (now the NCA), Ganga Ram Hospital, Lady Mclagan Girls High School, the chemistry department of the Government College University, the Albert Victor wing of Mayo Hospital, Sir Ganga Ram High School (now Lahore College for Women) the Hailey College of Commerce, Ravi Road House for the Disabled, the Ganga Ram Trust Building on Shahrah-e-Quaid-e-Azam, and the Lady Maynard Industrial School. He also constructed Model Town, a suburb that has recently developed into a cultural center for Lahore's growing socioeconomic elite.
