Rules of War -- Dharmayuddha and the Geneva Conventions

War, in the Hindu tradition, is never just violence. It is a moral event. Every arrow has an ethical weight. Every strategy carries a dharmic price. The Mahabharata -- the longest epic poem in human history, seven times the combined length of the Iliad and Odyssey -- is fundamentally a sustained argument about whether rules can survive the chaos of war, and what happens to civilisation when they do not.

The concept of Dharmayuddha (righteous war) is not a vague aspiration. It is a codified system of rules, debated by warriors, endorsed by kings, and refereed -- in theory -- by senior commanders. These rules predate the Geneva Conventions by approximately three thousand years. Some are strikingly similar. Others are more restrictive than anything modern international humanitarian law has produced. And the Mahabharata's most devastating insight is not that such rules existed, but that every single one of them was broken during the war -- systematically, escalatingly, and with consequences that haunt the victors more than the defeated.

The codified rules of Dharmayuddha, as described across the Mahabharata (primarily Udyoga Parva and Shanti Parva) and Kautilya's Arthashastra (4th century BCE), form a remarkably comprehensive framework. The core prohibitions cluster into several categories that map directly onto modern international humanitarian law.

The first and most fundamental: fight only equals. A horseman must not attack a foot soldier. A charioteer must not attack a horseman. An armed warrior must not attack an unarmed one. A warrior engaged with another opponent must not be attacked from behind. This principle of proportional engagement has no direct modern equivalent at the individual level -- even the Geneva Conventions do not require combatants to match each other in equipment.

The second: temporal restrictions. Fighting must cease at sunset and resume at sunrise. Night attacks are prohibited. During the night, opposing warriors may socialise, share water, and even tend each other's wounds. The Mahabharata records instances of Kaurava and Pandava warriors eating together at night during the 18-day war. This is not idealism; it is recorded practice.

The third: non-combatant immunity. Women, children, the aged, Brahmins, farmers tilling fields, merchants transporting goods, and anyone not bearing arms must not be attacked. Animals not serving a military function (particularly cows and elephants not in war formation) are protected. Medical personnel tending to the wounded are immune. Supply carriers providing food and water are immune.

The Mahabharata's true genius is not that it presents these rules as aspirational ideals. It presents them as rules that were broken -- and then it forces you to watch the consequences.

The first major violation occurs on Day 10 when Arjuna uses Shikhandi as a human shield against Bhishma. Bhishma had vowed never to fight someone born female, and Shikhandi was born as Amba in a previous life. The Pandavas exploit this vow. Technically, Arjuna fires the arrows. Morally, the entire tactic is a deception that violates the spirit of equal combat.

On Day 13, Abhimanyu -- a sixteen-year-old boy -- is trapped in the Chakravyuha formation and killed by seven warriors simultaneously. This violates the one-on-one combat rule, the prohibition on attacking a minor, and the ban on ganging up on a single warrior. The Kaurava commander Drona sanctions it. The moral damage is irreversible.

Day 14 brings the death of Jayadratha, which Arjuna accomplishes only because Krishna creates a false sunset using his Sudarshana Chakra. The Kauravas, believing the day has ended and the fighting rules apply, lower their guard. Arjuna strikes. This violates the temporal restriction on combat and involves divine-level deception.

Day 15 sees the death of Drona himself through a direct lie. Yudhishthira -- known as Dharmaraja, the king of righteousness -- tells Drona that 'Ashwatthama is dead' (referring to an elephant, not Drona's son). Krishna instructs him to mumble the clarification. Drona, grief-stricken, lays down his weapons and is killed. The most righteous man on the Pandava side has committed the most unrighteous act of the war.

By Day 18, when Duryodhana is struck below the waist by Bhima in their mace duel -- violating the explicit rules of Gadayuddha -- the moral framework has completely collapsed. Both sides have committed war crimes. The victory is hollow. Gandhari, mother of the Kauravas, curses Krishna and the entire Yadava clan to destruction. The curse is fulfilled. The Mahabharata does not allow its heroes to escape the consequences of broken rules.

Kautilya's Arthashastra, composed roughly in the 4th century BCE, takes a harder line than the Mahabharata. Kautilya distinguishes between Dharmayuddha (open battle with declared rules), Kutayuddha (covert warfare involving espionage, assassination, and economic sabotage), and Mantrayuddha (diplomatic warfare waged through alliances and propaganda). He considers all three legitimate tools of statecraft.

Yet even Kautilya imposes constraints. Conquered territories must be administered justly. Prisoners who surrender must be spared. Religious institutions must not be targeted. Agricultural land must be preserved because it feeds the very population the conqueror now governs. This is not morality for its own sake -- it is strategic morality. Kautilya understands that a ruler who destroys what he conquers rules over nothing.

For any UPSC aspirant preparing for General Studies Paper IV (Ethics) in Old Rajinder Nagar, the Dharmayuddha framework is not a footnote. It is a primary source for Indian ethical tradition in governance and warfare. The Indian Armed Forces' own doctrine of 'minimum force' in counter-insurgency operations traces its philosophical lineage to these texts. When the Indian Army operates under the Armed Forces Special Powers Act (AFSPA) in disturbed areas, the internal debate about proportionality and civilian protection echoes arguments that Bhishma and Arjuna had on the fields of Kurukshetra.
