Mahajanapadas, Buddhism and Jainism

This topic gives 4 questions and is the most Bihar-centred in ancient history, because the sixth century BCE happened largely on Bihar soil. Magadha rose here, the Buddha was enlightened here and Mahavira died here, and the paper knows it.

The Sixteen Mahajanapadas

By the sixth century BCE, sixteen large states or mahajanapadas had emerged in northern India. Four competed for supremacy: Magadha, Kosala, Vatsa and Avanti, and Magadha won.

Reason Magadha roseDetail
Iron oreRich deposits nearby for weapons and tools
Fertile landThe alluvial Ganga plain gave a large surplus
ElephantsForests supplied war elephants, used in battle
RiversGanga and Son gave trade routes and natural defence
CapitalsRajgir, and later Pataliputra at a river confluence
RulersBimbisara, Ajatashatru and Mahapadma Nanda were ambitious

The geographical reasons are what the question usually asks for, because they explain why Magadha and not Kosala. Bihar's own iron, soil, elephants and rivers are the answer.

Note also Vajji or Vrijji, with its capital at Vaishali, which was a gana-sangha — a republic governed by an assembly rather than a king. Vaishali is often described as among the earliest republics in the world, and it is a fact a Bihar paper is very likely to use.

Buddhism

FactDetail
FounderSiddhartha Gautama, the Buddha
BornLumbini, in Nepal
EnlightenmentBodh Gaya, in Bihar, under a peepal tree
First sermonSarnath, near Varanasi — the Dharmachakra Pravartana
DeathKushinagar, in Uttar Pradesh
Language of teachingPali
  • The Four Noble Truths and the Eightfold Path are the core teaching.
  • The Middle Path avoids both indulgence and extreme austerity.
  • The Tripitaka — Vinaya, Sutta and Abhidhamma — is the canon.
  • Two main sects: Hinayana and Mahayana.

Jainism

  • Mahavira was the twenty-fourth and last Tirthankara; Rishabhadeva was the first.
  • He was born at Kundagrama, near Vaishali, in Bihar.
  • He attained nirvana at Pawapuri, in Nalanda district of Bihar.
  • The Triratna are right faith, right knowledge and right conduct.
  • The five vows add brahmacharya to Parshvanatha's four; ahimsa is the central principle.
  • Two sects: Digambara and Svetambara.

Note the symmetry the paper likes: the Buddha was enlightened in Bihar and Mahavira was born and died in Bihar. Both taught in the people's language rather than Sanskrit, and both rejected the ritual and hierarchy of later Vedic religion.

Three of the first four councils were held in Bihar. That single line is among the strongest Bihar facts in ancient history and is very likely to be asked in a state paper.

TRE pointer: This is the richest Bihar topic in ancient history. Four items are near-certain: the geographical reasons for Magadha's rise, Vaishali as a republic, the Bodh Gaya and Pawapuri pairing, and the fact that three of the first four Buddhist councils met in Bihar. The commonest trap is placing the Buddha's birth in India — Lumbini is in Nepal, though the enlightenment at Bodh Gaya is in Bihar.

60-Second Recap

  • Sixteen mahajanapadas; Magadha won because of iron, soil, elephants and rivers.
  • Vajji, capital Vaishali, was a republic governed by an assembly.
  • Buddha born at Lumbini in Nepal, enlightened at Bodh Gaya, first sermon at Sarnath, died at Kushinagar.
  • Mahavira, the 24th Tirthankara, born near Vaishali and died at Pawapuri — both in Bihar.
  • Buddhist canon is the Tripitaka; Jain principles are the Triratna and ahimsa.
  • First three Buddhist councils met at Rajgir, Vaishali and Pataliputra — all in Bihar.

Frequently Asked Questions

Why did Magadha rise above the other mahajanapadas?

Because of geography as much as leadership. It had iron ore nearby for weapons, the fertile alluvial Ganga plain for a food surplus, forests supplying war elephants, and the Ganga and Son rivers for trade and defence. Its capitals, Rajgir and later Pataliputra, were well sited.

Where was the Buddha born and where was he enlightened?

He was born at Lumbini, in present-day Nepal, and attained enlightenment at Bodh Gaya in Bihar under a peepal tree. He gave his first sermon at Sarnath and died at Kushinagar. Placing the birth in India is the most common error.

Which Bihar places are linked with Mahavira?

He was born at Kundagrama near Vaishali and attained nirvana at Pawapuri in Nalanda district, both in Bihar. He was the twenty-fourth and last Tirthankara, Rishabhadeva being the first, and ahimsa is the central principle of his teaching.

Where were the Buddhist councils held?

The first at Rajagriha under Ajatashatru, the second at Vaishali under Kalashoka, the third at Pataliputra under Ashoka, and the fourth in Kashmir under Kanishka. Three of the first four were therefore held in Bihar, which state papers ask about directly.
