So What if Dara Shikoh had defeated his brother Aurengazeb in the Mughal civil war. With the tolerant and pluralistic Dara at the helm how would the Mughal Empire have developed and what would his reign impact be on the subcontinent?
I believe Tony Jones' Gurkani Alam is a TL which delves into a PoD such as this.
But basically the outcome is that Dara Shikoh, a very religiously tolerant and forward thinking monarch (if a bit weak-hearted), gains the throne leading to butterflies that posiblly continue the Mughal Golden Age for another 100 or so years.
If Shivaji was to still rise he will be remembered as just another warlord and the Maratha Empire/Confederacy is completely butterflied away.
