Inter-State Relations and Diplomacy in the Shantiparva

When the Kurukshetra war ended, the dying patriarch Bhishma did not just speak about prayer and salvation. From his bed of arrows, he gave Yudhishthira a practical manual on how a king should deal with other kingdoms. This portion of the Shantiparva, the twelfth book of the Mahabharata, contains a surprisingly detailed discourse on what we would today call international relations. Bhishma treats diplomacy as a serious science, balancing moral duty with hard-nosed strategy, and his advice on alliances, intelligence, and the ethics of war still echoes in modern statecraft.

Diplomacy as a science of statecraft 🔗

The Shantiparva does not view dealings between kingdoms as random or emotional. It frames inter-state relations as a structured discipline that a ruler must master. The Shanti Parva is essentially a treatise on the duties of a king and his government, covering law, justice, and the conduct of foreign affairs. Within this, the management of relations with neighbouring states forms a distinct and important division of polity.

This ancient tradition of thinking about diplomacy is one of the oldest in the world. Indian thought on the state, law, and statecraft draws from the Vedas, Smritis, Upanishads, and Puranas, and diplomacy as a concept appears prominently in texts like the Manusmriti, Kautilya’s Arthashastra, and the Shantiparva of the Mahabharata. What makes the Shantiparva distinctive is that it places these practical instructions inside a moral framework. A king is told not only how to win, but also why some victories destroy the victor.

The king as the centre of foreign policy 🔗

In the Shantiparva, the king is the real executive who carries out functions defined by dharma. He is both the appointing and the removing authority for officials. When it comes to relations with other states, the responsibility rests squarely on him. It was specifically the duty of the king to appoint spies and ambassadors and to gather information about the defence of the state. This makes foreign policy a personal duty of the ruler, not something to be delegated and forgotten.

The four methods: sama, dana, bheda, and danda 🔗

The most enduring contribution of this tradition is the framework of four diplomatic methods, known as the four upayas. These are conciliation, gifts, dissension, and force. They are designed to make an opponent bend to the will of the king who seeks to expand his influence.

The four methods follow a clear hierarchy. The order of preference runs from sama to dana to bheda, with danda or the use of force reserved as the last resort. Each can be used alone or in combination, and the different methods reinforce one another when applied together.

Sama: conciliation first 🔗

Sama means peaceful negotiation and conciliation. It is achieved by praising another party’s good qualities and emphasising shared interests. This is the preferred starting point. A wise ruler tries persuasion and goodwill before reaching for any other instrument, because peace preserves resources and avoids the long-term damage of conflict.

Dana: offering incentives 🔗

Dana means winning over an opponent through gifts, concessions, or material rewards. In practical terms, this resembles modern economic diplomacy, where trade agreements, aid, and incentives are used to build cooperation. It is a step up from pure persuasion but still avoids hostility.

Bheda: creating divisions 🔗

Bheda means sowing dissension within the enemy’s ranks. This is the more cunning side of diplomacy. The idea is to win over those in the enemy’s territory who can be seduced away through conciliation and gifts, and to handle the rest through dissension and force by pointing out the enemy’s defects. Breaking an opponent’s unity from within is often cheaper and safer than open battle.

Danda: force as the last resort 🔗

Danda means punishment or the use of armed force. It sits at the bottom of the hierarchy precisely because it is the most destructive and least desirable. The Shantiparva consistently treats war as something to be avoided where possible, deployed only when the gentler methods have failed.

A famous example of all four methods in action is Krishna’s mission to the Kauravas before the war. As a peace envoy, Krishna first tried conciliation by appealing to family unity, then offered terms, then suggested isolating the one obstinate person, and finally warned of the consequences of war. This shows how the four methods were meant to be used in sequence, escalating only when necessary.

The role of spies and ambassadors 🔗

Bhishma is emphatic that no king can manage inter-state relations without reliable information. The Shantiparva insists that a spy system and ambassadors are essential. Intelligence is the foundation on which every diplomatic decision rests.

Spies as the king’s eyes 🔗

The Shantiparva describes various types of spies and their specific functions. The phrase that spies are the king’s eyes was well established in this tradition, with a vivid comparison stating that cows perceive by smell, priests by knowledge, and kings by their spies, while ordinary people see only through their eyes. A good spy was expected to endure hunger, thirst, and hardship and to operate in disguise without drawing attention.

This intelligence network was put to use throughout the Mahabharata itself. In the war narrative, spies form part of the camp and are repeatedly sent across enemy lines to assess strength. Yudhishthira speaks of spies placed in Duryodhana’s army bringing him news each morning, and the enemy similarly used spies to track the Pandavas’ plans. This is not abstract theory but a practice woven into the epic’s events.

Ambassadors as the mouthpiece of the king 🔗

The ambassador, or duta, held a position of great responsibility and was regarded as the mouthpiece of the king. An envoy was expected to know how to conduct himself in a foreign court, to remain patient until his mission was complete, and not to be swayed by the honours offered to him. He was also expected to live a disciplined and moral life while abroad.

Importantly, this tradition recognised a form of diplomatic immunity. Envoys were not to be abused, tortured, or killed, and were to be sent back unharmed once their mission ended. This principle, found across the epics, anticipates the modern idea that diplomats enjoy protection regardless of the message they carry. The connected text of the Manusmriti even states that peace and war ultimately depend on the ambassador, underlining how central this role was to statecraft.

Pragmatism tempered by caution 🔗

Bhishma’s counsel on inter-state relations is strikingly realistic. He advises the king to break the enemy’s ranks using both straightforward and cunning diplomatic means. He also warns against complacency. A powerful king must not neglect even a weak enemy, because, as the text puts it, a small spark can cause a great flame and even a slight poison can cause death. An enemy sheltering in a fort, even with limited resources, can trouble a prosperous kingdom.

This caution extends to treaties. Bhishma advises that even after concluding a treaty with an enemy, a king should not place complete trust in him. This is a sober recognition that agreements between states are held together by interest, not sentiment, and that vigilance must continue even during peace. The emphasis on a strong defensive base reflects the wider tradition in which a fortified capital, a full treasury, a capable army, and reliable allies were all counted among the essential limbs of a stable state.

Dharma vijaya: the ethics of conquest 🔗

What separates the Shantiparva from a purely cynical guide to power is its insistence on righteousness. The text advocates dharma vijaya, or victory through righteous means, over adharma vijaya, or victory through unrighteous means.

The logic here is consequential, not merely sentimental. The teaching is that if a king obtains victory through recourse to adharma, he only prepares the ground for his own eventual destruction. Virtuous people who choose the path of dharma can defeat evildoers. In other words, an unjust victory plants the seeds of future ruin, while a just one builds lasting stability. This idea finds a famous later parallel in Emperor Ashoka, who after the Kalinga war turned away from military conquest and committed himself to dhamma-vijaya, winning through dharma rather than through war.

Why long-term thinking matters 🔗

The Shantiparva repeatedly stresses the long-term consequences of decisions made in inter-state conflict. A king is encouraged to weigh not just the immediate gain of an action but its eventual fallout for his dynasty and his people. This is why force sits at the bottom of the hierarchy of methods, and why even a clever diplomatic trick must be measured against the standard of dharma. The framework asks rulers to think in decades, not days.

Echoes in modern diplomacy 🔗

The structure Bhishma describes maps neatly onto contemporary international relations. Conciliation resembles diplomatic dialogue, gifts resemble economic incentives and aid, dissension resembles efforts to divide rival coalitions, and force resembles military action as a last resort. The reliance on spies and ambassadors corresponds directly to today’s intelligence agencies and diplomatic corps.

The deeper lesson, however, is the balance between pragmatism and ethics. The Shantiparva does not pretend that states can survive on goodwill alone, nor does it accept that anything goes in the pursuit of power. It argues that the most durable success comes from combining shrewd strategy with moral restraint. For a tradition often dismissed as merely religious, this is a remarkably mature theory of how power and principle can coexist.

What do you think? If even an ancient text warned that victory through unrighteous means sows the seeds of future ruin, how well do modern states actually live up to the idea of dharma vijaya? And in an age of cyber-surveillance and economic pressure, which of Bhishma’s four methods do you think dominates international relations today?
