Dunno, but this question is really worth pondering.
All the sides of India have produced great Emperors - Chandragupta from East India or Chola from South India
The only notable Pakistani Emperor was Ranjit Singh.
Apart from that - zilch! In its entire history, Pakistan has built no empire nor produced a great king to boast of! Pakistan has more or less been invaded and conquered either by its East(Indian empires) or West(Iranian or Afghan empires).
you stupid people, Pakistan has been producing emperors one after another and name a few, Bhuttos, Zardari, Nawaz Sharif and even janab honorable Altaf hussain.
Sher Shah Suri...the greatest emperor sub continent has ever seen and had he not died in an accident...we might have a totally different India today
