Hello friends, I have read about the history of Porus and it has many difference in comparison to the show. I can give you many examples like in the first episode of Porus at the ending scene their was a blast when takshashila army and its King were going back from Puru rashtra but in real history nothing like that was happened. In books they were directly attacked by Puru Rastra Kings brother.
Like this they have changed many things.
Its story is changed by the shows writer which I dont like.
