The Mahābhārata War (the Kurukshetra War) is a massive civil war between two branches of the same royal family:
The Pāṇḍavas – five brothers who try to rule ethically
The Kauravas – one hundred cousins who seize power through deception
After failed attempts at peace, the conflict escalates into a catastrophic 18-day war involving almost every kingdom of the known world at that time.
