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.
