Punjabi nationalism
In the 19th century, due to politics of congress, dominated by the Hindi speaking, UP-ite Hindu leaders of UP, CP, Hindu Punjabi's started to prefer the Hindi language instead of Punjabi by declaring the Hindi as a language of Hindus and started to become clones of Gunga Jumna culture and traditions with the loss of their own Punjabi identity. Later on, Muslim Punjabi’s did the same and started to become the clones of Gunga Jumna culture and traditions with the loss of their own Punjabi identity, because of preferring the Urdu language upon Punjabi by declaring the Urdu as a language of Muslims, due to the influence of the Muslim League, dominated by the Urdu speaking, UP-ite Muslim leaders of UP, CP and presence of UP-ite Muslims in Punjab.
