Kautilya’s Six War Tactics: Strategies for State Survival and Expansion

Imagine you are a king in ancient India, surrounded by neighbours who eye your territory with suspicion. Some are stronger than you, some weaker, and some simply waiting to see which way the wind blows. How do you survive? How do you grow? Kautilya, the strategist behind the Mauryan Empire, answered this question more than two thousand years ago in his Arthashastra. His answer was the Shadgunya-a set of six foreign policy tactics that a ruler could deploy depending on the balance of power. These six measures remain one of the earliest and most systematic frameworks for statecraft anywhere in the world.

What is Shadgunya? 🔗

The word Shadgunya literally means “six measures” (Shad = six, Gunya = measures or strategies). It refers to the six options available to a ruler when dealing with rival states. According to Kautilya, a wise king must study his own position, compare his strength with that of his neighbours, and then pick the policy that best serves his interest. There is no fixed rule. The right choice depends entirely on circumstances-the relative power of the states involved, the timing, the geography, and the resources at hand.

This flexibility is what makes the doctrine so powerful. It rejects simple binary thinking. War is not always the answer, and neither is peace. A ruler has six distinct tools, and the skill lies in knowing which one to use and when.

The link with the Mandala theory 🔗

Shadgunya does not stand alone. It flows directly from Kautilya’s famous Raja Mandala, or “circle of states.” In this scheme, the ambitious king at the centre is called the Vijigishu-the would-be conqueror. The Mandala theory assumes that states sharing a border are natural enemies, because both want to expand into the same space. The state beyond that enemy, however, becomes a natural ally. This is the ancient version of the idea that “the enemy of my enemy is my friend.”

The Mandala thus maps out who is a likely friend and who is a likely foe based on geography. Shadgunya then provides the playbook for action. Once a king knows where he stands in the circle of states, he selects one of the six measures to deal with each rival. In short, the Mandala tells the king the lay of the land, and Shadgunya tells him what to do about it.

The six tactics explained 🔗

Kautilya laid out the six measures clearly. Each one is suited to a different power situation. Let us walk through all six.

Sandhi (peace) 🔗

Sandhi means making a treaty or peace agreement. Kautilya advised this policy when a ruler faces an enemy who is clearly stronger than himself. When you cannot win, you do not fight. Instead, you negotiate peace-even on the enemy’s terms, which might mean surrendering troops, treasure, or territory.

But Sandhi is not surrender in spirit. It is opportunism. By buying peace, a weaker king gains time to rebuild his strength and wait for the stronger enemy to weaken. The treaty becomes a breathing space, not a defeat. Kautilya even applied a kind of cost-benefit analysis here: if the cost of war seems higher than its benefit, Sandhi is the smarter choice.

Vigraha (war) 🔗

Vigraha is the policy of open hostility or war. Kautilya recommended it for a stronger nation facing a relatively weaker enemy. When the elements of your state are more substantial than those of your rival, war becomes a viable option to expand power or secure interests.

Importantly, Kautilya did not glorify war. He favoured resolving conflict through diplomacy whenever possible and treated armed force as the last remedy. War is expensive and risky. A ruler should reach for it only when victory is reasonably assured and when the gains outweigh the losses.

Asana (neutrality) 🔗

Asana is the policy of staying quiet-a posture of watchful neutrality. A king adopts Asana when neither war nor alliance offers a clear advantage, and the wisest move is to wait. The ruler holds his position and observes.

This waiting is far from passive. The goal is to let the enemy weaken on its own, perhaps by getting entangled in difficulties or by being drawn into a war on another front. Kautilya even suggested that Asana could include secret efforts to undermine the rival-what we might today call a covert or proxy approach. Neutrality, in his hands, was a calculated pause rather than a permanent stance.

Yana (preparation for war or marching) 🔗

Yana means marching on a military expedition or preparing to do so. It is the active expression of hostility-the next step beyond Vigraha. Kautilya advised Yana when a king is confident of defeating the enemy and overpowering him.

Yana can also be understood as a show of strength designed to pressure a rival without necessarily fighting. By mobilising forces and demonstrating readiness, a ruler can coerce a weaker neighbour into concessions. This is the diplomatic muscle behind the threat of force, and it works best when the king genuinely holds the upper hand.

Samshraya (seeking shelter or alliance) 🔗

Samshraya means seeking protection by allying with a more powerful king or by taking refuge in a fort. Kautilya recommended this measure when a state becomes so weak that it cannot defend itself alone against a powerful aggressor.

Crucially, Kautilya did not see this as shameful. Seeking shelter is a calculated act of survival. A king who lives to fight another day has lost nothing permanently. The classical texts put it simply: one who is weaker should forge an alliance with the strong. Through such protection, even a weak king can eventually grow powerful again.

Dvaidhibhava (dual policy or duplicity) 🔗

Dvaidhibhava is the double-game-pursuing peace with one state while simultaneously waging or preparing for war with another. Kautilya advised this measure for a king of moderate strength, who is not strong enough to fight everyone but not weak enough to merely seek shelter.

The classical image of Dvaidhibhava is striking: holding a garland of friendship in one hand and a sword in the other. By making peace with the stronger rival and attacking the weaker one, a middle-power king balances his enemies and steadily improves his own position. It is the most sophisticated of the six measures, requiring sharp judgement about whom to befriend and whom to strike.

How a king chooses 🔗

The genius of Shadgunya lies in the principle of selection. Kautilya did not tell rulers to follow one tactic blindly. He taught them to read the situation first. As a rough guide, a weak king should choose Sandhi or Samshraya, a strong king should consider Vigraha or Yana, and a king of middling power may find Asana or Dvaidhibhava most useful.

The decision rests on comparing the constituent elements of the state-often analysed through Kautilya’s related Saptanga theory of the seven limbs of the state. A ruler weighs his army, treasury, territory, allies, and other resources against those of his rival. Only after this honest assessment does he pick his measure. Kautilya famously wrote that a ruler who understands the six measures as interdependent can play with rival kings as he pleases.

The four upayas as support 🔗

The six measures rarely operate alone. They are reinforced by the four upayas, or devices, used to settle conflicts among rival powers. These are Sama (conciliation), Dama (gifts or inducement), Danda (force or punishment), and Bheda (creating division among enemies). A king might use peaceful persuasion, then offer incentives, then sow discord among rivals, and only finally resort to force. Together, the upayas give the ruler graded tools to make his chosen Shadgunya strategy effective.

Why these tactics still matter 🔗

Although the Arthashastra was written around the fourth century BCE, the logic of Shadgunya maps surprisingly well onto modern foreign policy. Scholars often compare Kautilya’s realism with that of Niccolo Machiavelli, though Kautilya’s framework is broader and more systematic.

Consider the parallels. A nation signing a treaty to avoid escalation is practising Sandhi. A country displaying military power in a contested region is practising Yana. A smaller state aligning with a superpower for security is practising Samshraya. And a middle power that improves ties with one rival while building up its armed forces against another is practising Dvaidhibhava. In fact, the situation Kautilya described-a central state surrounded by competing neighbours and shifting alliances-closely mirrors the strategic environment of contemporary South Asia, where states constantly recalculate friendships and rivalries.

What endures is the underlying insight: power is relative, alliances are temporary, and survival demands flexibility. Kautilya never assumed that any single approach would always work. His doctrine teaches rulers to assess, adapt, and act-a lesson as relevant in the council chambers of today as it was in the Mauryan court.

What do you think? If you were advising a state of moderate strength caught between a powerful rival and a weaker one, would you choose the duplicity of Dvaidhibhava or the patience of Asana? And do you think a framework built for ancient kingdoms can genuinely guide a modern democracy’s foreign policy, or does it risk reducing complex diplomacy to a game of power alone?
