I've got the Maurya and Gupta Empires there... but there will be more. On my todo list!
Guptas and Mauryas came after Christ .. much later . ..
Vaidik period began around five thousand years before Christ .. The history was well documented in `Mahabharata` . In fact - Mahabharata was the first historical narrative .. kinda wikipedia of that time :-)
It was transated into English first by Kishori Mohan Ganguly in 1896 .. https://mahabharata.shutri.com/
On a larger version I have the Indus Valley civilisation, Harappa, Vedic period... but the Mahabharata will definitely go in there as well!
Thanks!
