The province or Sooba Sarhad or NWFP or North West Frontier province was formed by partitioning the Punjab province or Sooba Punjab in 1902.
Even though Punjab was partitioned in 1902, NWFP did not become FULL province until 1935.
This makes NWFP the youngest entity among the provinces of Pakistan.
People who are crying to name or rename Sooba Sarhad forget that Pashtoons had two major chances (1902 and 1935) to rename the province to Afghania, Khyber, Abaseen, Pakhtoonkhwah etc. But for some reason they did not.
The grand leader from Sooba Sarhad, aka Khan Abdul Gaffar Khan was around when NWFP was given full provincial status. Did he start a movement to change the name of the province?
Perhaps Bacha or Badshah Khan wanted to be part of greater India, and thus ethnic nationalism was not big on his agenda.
Perhaps he wanted to maintain peace and harmony in Pakistan, so ethnic nationalism was not on his agenda after 1947.
BTW Bacha Khan always found Punjab as an oasis whenever his Pashtun opponents made his life difficult.
Thus as long as Bacha Khan was alive, things were a lot less ethnic.
It was only after his death, that Bacha Khan’s son Wali Khan adopted ethnic nationalism as his stance. This was supported by the socialists and communist sympathizers in the Frontier and Afghanistan. These socialists and ethnic nationalists received funding from the Soviet Union and Soviet-lackey India.
We must remember that no province has any hate against Pashtuns. It is OK to name Sarhad to the name of their choosing. But in doing so they must remember that the responsibility of the current conditions in the province is largely due to the role of Pashtuns, and only they can change the conditions there, in order to benefit their province as well as the benefit of Pakistan.
