Aurangazeb is correct word for CBN..
He worked his xxx off like Aurangazeb and when the succession time came, he fought for his rightful dues and took it.
This is what triggered Aurangazeb:
Shah Jahan was outraged to see Aurangzeb enter the interior palace compound in military attire and immediately dismissed him from his position of Viceroy of the Deccan, Aurnagzeb was also no longer allowed to use Red tents (an imperial prerogative, which Shah Jahan handed over to Dara Shikoh) or associate himself with the official military standard of the Mughal Emperor.[9]
