The history mainly: the mysterious Indus/Harappa civilization, the arrival of the Arrians and Sankrit, the great empires of old (Maurya, Gupta etc), the Mughal empire and British India. History has been my special interest since early childhood. I first got interested in India somewhere in Elementary school, as part of my history obsession (My interest sort of 'hops' from period to period and region to region).
Despite the terrible things that happen and have happened in India, I imagine it at as a sort of Paradise on Earth, not sure why. That's why I get excited when I read or hear something about India. I think the country has a lot of potential, just look at the fact that they recently put a object in Mars's orbit!
Do you prefer modern- or historic South Asia?
