The OP is correct that no emperor or King came from Pakistan , the time of emperors and kings was long over by 1947 , when modern day Pakistan was born
Before 1947 , if we go back many 1000 years then we had one of the earliest civilised society the IVC , which was associated with farming and trade, there is no indication that IVC functioned like a kingdom , which is good
If we go back a few 100 years, then our land was part of various feuding kingdoms
We can say that in recent history , up until modern day Pakistan was born , we were the garrison and the garinery and after 1947 while we have retained the characteristic of being the grainery and the garrison we have also grown to become a nuclear power
Our birth , our faith and our ability to tear the rear of our enemies in present times is ultimately the cause of great heart ache to the enemies which makes them wonder how and why this came about
