Date of Mahabharata war has been a debatable issue for very long. Still, we don't find a unanimous opinion. Traditional belief is that it happened around 3130 BCE, just before the start of Kaliyuga. Unfortunately, we couldn't find any archaeological proof to support it. Even though marine archaeological discoveries in and around Dwaraka point towards that direction, we need more supporting evidence. But it was true that a war happened long ago. I have summarised the opinion of three sets of scholars.
