Around 1837 a British official at the Calcutta mint named James Prinsep cracked a puzzle that had baffled scholars for decades. Inscriptions in an unknown script were scattered across India on rocks and polished stone pillars, many of them in the name of a king called Devanampiya Piyadasi, "Beloved of the Gods, of gracious look". James Prinsep deciphered the Brahmi script in 1837, and over the following years scholars matched the mystery king with Ashoka, a Maurya emperor known from Buddhist chronicles. A ruler half lost to legend suddenly spoke in his own words.

Alexander and Chandragupta

The Maurya story begins with an outsider's failure. Alexander the Great's army reached the Punjab in 326 BCE, then mutinied at the Beas River and turned back. Alexander had defeated a local king, Porus, but his soldiers refused to march further east toward the Ganges kingdoms. Within a few years Greek garrisons in the northwest had collapsed. Into the vacuum stepped a young ruler named Chandragupta Maurya. Chandragupta founded the Maurya Empire around 321 BCE, overthrowing the Nanda kings of Magadha and ruling from Pataliputra, near modern Patna. He fought Seleucus, Alexander's successor in the east, and then made peace, trading war elephants for territory in what is now Afghanistan.

Seleucus sent an ambassador. Megasthenes, the Seleucid envoy at Pataliputra, wrote a description of India called the Indika. The book is lost, but later Greek and Roman writers quoted it. He described a vast walled capital, a large army, officials who supervised markets and roads, and society divided into seven classes, a scheme that does not match Indian accounts and shows how hard outsiders found it to read Indian society.

The science of power

Indian tradition credits Chandragupta's success to his adviser Kautilya, also called Chanakya. The Arthashastra, a treatise on statecraft attributed to Kautilya, covers taxation, spies, diplomacy, law and war with cool realism, advising kings to watch ministers closely and treat neighbors as likely enemies. Many scholars now think the text as we have it was compiled and expanded over several centuries, so it may describe an ideal state more than the actual Maurya one. Still, it shows that Indian thinkers developed a hard-headed political science long before Machiavelli.

Ashoka's turn

Chandragupta's grandson Ashoka ruled from about 268 to 232 BCE over an empire covering most of the subcontinent. Early in his reign he conquered Kalinga, on the east coast. In one of his own inscriptions, Ashoka wrote that the Kalinga war, around 261 BCE, left 150,000 people deported and 100,000 killed, and that he felt deep remorse for it. No other ancient conqueror is known to have publicly expressed regret for a war he won.

Afterwards Ashoka promoted what he called dhamma: a moral code of tolerance, restraint, kindness toward living beings, and respect for parents, elders and teachers. He became a Buddhist lay follower, but his dhamma was not a demand to convert; he urged respect for all religious groups and warned against praising one's own sect while disparaging others. He reported building wells and rest houses, planting shade trees, providing medical care for people and animals, and appointing officials to spread dhamma. His edicts were carved on rocks and pillars, mostly in Prakrit in the Brahmi script, with versions in Greek and Aramaic in the northwest, so that people in different regions could hear them read aloud.

Ashoka was not a pacifist ruler of a gentle utopia. He kept the army. He did not abolish the death penalty, though he granted condemned prisoners a reprieve of three days. Historians argue over how far his reforms reached and whether dhamma was sincere conviction, clever statecraft for holding a diverse empire together, or both. The empire fragmented within about fifty years of his death, and the last Maurya was killed around 185 BCE. Yet Ashoka's memory endured. The lion capital from his pillar at Sarnath became the national emblem of the Republic of India, and the wheel on the national flag comes from Ashokan art.

Worked example: reading Rock Edict XIII

Rock Edict XIII is the inscription that describes Kalinga. Ashoka says that the killing and deportation of the people of Kalinga grieves him, and that the suffering of ordinary people, including Brahmins, ascetics and householders whose loved ones were harmed, weighs on him most. He declares that conquest by dhamma is the best conquest. It is a moving text.

Read on, though. The same edict tells the forest peoples living within his lands that the emperor, for all his remorse, still has power, and that they should change their ways if they do not want to be punished. And the edict was not carved at Kalinga itself; the versions found there leave out the passage about the war and substitute other instructions to local officials. What does this tell us? Ashoka's regret was public and probably real, but it was also addressed to particular audiences, and a ruler who apologizes still governs. Reading a powerful person's words for both sincerity and purpose is not cynicism. It is how we take them seriously.
