Punjabi language
Doabi is spoken in both the Indian Punjab as well as parts of Pakistan Punjab owing to post-1947 migration of Muslim populace from East Punjab. The word "Do Aabi" means "the land between two rivers" and this dialect was historically spoken between the rivers of the Beas and the Sutlej in the region called Doaba. Regions it is presently spoken includes the Jalandhar, Hoshiarpur and Kapurthala districts in Indian Punjab, specifically in the areas known as the Dona and Manjki, as well as the Toba Tek Singh and Faisalabad districts in Pakistan Punjab where the dialect is known as Faisalabadi Punjabi.
Punjabi nationalism
Beside the fact that, in 1800 century, religious ratio of Punjabi people in Punjab was 48% Muslim Punjabis, 43% Hindu Punjabis, 8% Sikh Punjabis and 1% others, but due to attraction of the various tribes, castes and the inhabitants of the Punjab into a broader common "Punjabi" identity and uniting by natural affinity of "Punjabi Nationalism", Punjab was a secular regime, Punjabi was a secular nation and after throwing out the Muslim Mughal invaders of Punjab from Delhi, India and Muslim Afghan invaders of Punjab from Kabul, Afghanistan, a Sikh Punjabi, Maharaja Ranjit Singh was the ruler of Punjab, which provided the boost to the already initiated Punjabi nationalism.
