The Mauryan Empire (c. 322 BCE - 185 BCE)

The foundation of the Mauryan Empire represents a unique epoch in Indian history. For the first time, a large portion of the Indian subcontinent was united under a single paramount administration. The primary literary sources for this period are Kautilya's Arthashastra (statecraft and administration) and Megasthenes's Indica (social and political observations), alongside the ubiquitous inscriptions of Ashoka.

1. Chandragupta Maurya (c. 322 BCE - 298 BCE)

• Foundation: He laid the foundation of the empire by overthrowing the unpopular Nanda ruler (Dhana Nanda) with the shrewd assistance of his mentor, Chanakya (also known as Kautilya or Vishnugupta), the author of the Arthashastra.
• Expansion and Conflicts: He dramatically expanded his territory westward. He famously defeated Seleucus I Nicator (a general of Alexander the Great) in 305 BCE. Following a treaty, Seleucus ceded vast territories (spanning modern Afghanistan and Balochistan) and sent his ambassador, Megasthenes, to the Mauryan court in Pataliputra.
• End of Life: According to Jain traditions (specifically the Parishishtaparvan), a severe 12-year famine enveloped Magadha. Chandlergupta abdicated his throne, became a Jain monk under the guidance of sage Bhadrabahu, and migrated south to Sravanabelagola (in Karnataka), where he starved himself to death (a practice known as Sallekhana/Santhara).

2. Bindusara (c. 298 BCE - 273 BCE)

• The son of Chandragupta, recognized by the Greeks as Amitrochates (Sanskrit "Amitraghata," meaning slayer of foes).
• Expansion: He is largely credited with extending the empire southward, covering the Deccan peninsula as far south as Mysore. He successfully suppressed a major rebellion in Taxila.
• Foreign Relations: He maintained friendly diplomatic ties with the Hellenic world. He requested a sweet wine, dried figs, and a sophist (philosopher) from the Syrian king Antiochus I (who sent only the wine and figs, refusing the philosopher).
• Religious Affiliation: He was a patron of the Ajivika sect (founded by Makkhali Gosala, believing in strict fatalism/destiny).

3. Ashoka the Great (c. 268 BCE - 232 BCE)

Ashoka succeeded Bindusara after a bloody war of succession ( Buddhist texts claim he killed 99 of his brothers, sparing only the youngest, Tissa). He took the titles "Devanampiya" (Beloved of the Gods) and "Piyadasi" (He who looks with affection).

The Kalinga War (261 BCE)

• This is the most crucial event in his reign and ancient Indian history. Fighting a ferociously bloody war to conquer Kalinga (modern Odisha), Ashoka witnessed the slaughter of nearly a hundred thousand people.
• Transformation: The unprecedented destruction filled him with profound remorse and sorrow (Bherighosha, the sound of war drums, was replaced by Dhammaghosha, the sound of Dhamma).
• He subsequently abandoned the policy of physical conquest in favor of cultural conquest. Under the influence of the Buddhist monk Upagupta, he formally embraced Buddhism.

Ashoka's Inscriptions

• He was the first Indian king to communicate directly with his subjects via edicts engraved on prominent rocks and highly polished sandstone pillars scattered across the empire.
• Scripts used: The edicts in the eastern part (India) were primarily written in the Brahmi script and Prakrit language. In the northwest (Pakistan/Afghanistan area), they were written in Kharosthi and Aramaic, and some in Greek (like the bilingual Kandahar inscription).
• Decipherment: The Brahmi script of the edicts was first deciphered by the British epigraphist James Prinsep in 1837.
• Important Edicts: The 13th Rock Edict extensively describes the horrors of the Kalinga War and Ashoka's transformation.

Ashoka's Dhamma

• Ashoka's "Dhamma" (Prakrit for the Sanskrit Dharma) was not a new religion or exclusively Buddhist doctrine.
• It was a sweeping moral code of conduct and an ethical framework for living, aimed at fostering social harmony and unity in his vast, diverse empire.
• It heavily emphasized: respect for elders and teachers, obedience to parents, non-violence towards all living creatures (abolished animal sacrifice), humane treatment of servants and slaves, and religious tolerance.
• He appointed special officials called Dhamma Mahamatras to actively propagate and enforce these ethical codes among the populace.
