The Mahabharata is an ancient Indian epic that tells the story of a dynastic struggle between two groups of cousins, the Kauravas and Pandavas, for the throne of Hastinapur. It describes how the Pandavas were ultimately betrayed and forced into exile. This led to a great war between the two sides that resulted in the death of many family members and allies. After many battles, acts of bravery and betrayal, the Pandavas were victorious over the Kauravas and ruled Hastinapur, but the costs of war were immense.
