Its a fake flag, like all information posted by Pashtuns.  Trying to glorify their history which really consisted of being defeated by the Mughals, Rajputs, Sikhs and then sucking up to the british.  Typical pashtun propoganda. Funny thing about this stupid flag is that is used a European Shield style and British King's crown.  Inferiority complexed people inventing history.  Only thing Yusufzai ever did was to provide Bibi Mubarika to Mughal Babur so he would stop raping them.  Manana
