Did the Persians, Mughals etc. just vanish in thin air.....without leaving any descendants????
Yes,
MAJORITY of them HAD Hindu ancestry.......
BUT a Muslim has to marry another Muslim right
!!!!......and when you marry another Muslim with Persian,Mughal ancestry.....your child becomes a Hybrid......and when your child marries another Muslim.....their child becomes Hybrid........and so on........simple logic.
Like this after so many generations, there is hardly any 'pure blood' left in the Muslims of the
whole Indian subcontinent either from the Indian side
OR from the Invader's side.....
