History
Mahajanapadas, Magadha and the Mauryan Empire
Rise of Magadha: Haryankas to Nandas
Rise of Magadha for CGPSC: Bimbisara, Ajatashatru, Shishunagas, Nandas, causes of Magadhan supremacy, and the Persian and Alexander invasions.
Prerequisites
- The Sixteen Mahajanapadas — the sixteen rivals, their capitals and the gana-sanghas
- Jainism and Buddhism — the Buddha and Mahavira were contemporaries of Bimbisara and Ajatashatru
The Hook: Why Not Kosala, or Avanti?
Connect
Think of the Chhattisgarh map: the state’s mineral belt (iron at Bailadila and Dalli-Rajhara), its forests and its rivers are exactly the resources that make a region powerful. In the 6th century BCE, Magadha in south Bihar had the same kind of advantage: iron ores nearby, elephant forests, fertile alluvium and rivers that worked as highways.
Four big monarchies (Magadha, Kosala, Vatsa and Avanti) fought for about two hundred years. Why did the small kingdom around Rajagriha end up ruling north India?
Why it matters: Prelims asks dynasty order, “who founded Pataliputra”, which council met under which king, and Alexander’s battle. Mains asks the causes of Magadha’s rise, a classic 150-word question.

Bimbisara (बिम्बिसार)
| Point | Detail |
|---|---|
| Dates | Traditionally c. 544–492 BCE |
| Capital | Girivraja / Rajagriha (राजगृह), ringed by five hills |
| Religion | Contemporary and patron of both the Buddha and Mahavira |
| Marriage diplomacy | Kosaladevi (sister of Prasenajit of Kosala), who brought a Kashi village as dowry; Chellana, a Lichchhavi princess (daughter of Chetaka); Khema of the Madra clan |
| Conquest | Annexed Anga (capital Champa), which gave Magadha the Ganga trade towards the coast |
| Diplomacy | Sent his royal physician Jivaka to treat Chanda Pradyota of Avanti; exchanged envoys with Gandhara |
Bimbisara is often called the first great ruler of Magadha because he used matrimonial alliances, conquest and diplomacy together.
Ajatashatru (अजातशत्रु)
| Point | Detail |
|---|---|
| Dates | Traditionally c. 492–460 BCE |
| Accession | Buddhist tradition says he killed his father Bimbisara |
| Wars | Fought Kosala (Prasenajit), which ended in a marriage alliance and Magadhan control of Kashi; then a long war with the Vajji confederacy, which he conquered |
| Military innovations | Jain texts credit him with the mahashilakantaka (a catapult hurling stones) and the rathamusala (a chariot fitted with a mace) |
| Fort | Fortified Pataligrama on the Ganga as a base against the Vajjis |
| First Buddhist Council | At Rajagriha (Saptaparni cave), soon after the Buddha’s death, under his patronage, presided over by Mahakassapa |
Udayin (उदयिन)
- Founded Pataliputra (पाटलिपुत्र), also called Kusumapura, at the confluence of the Ganga and the Son, and moved the capital there.
- A river-girt capital in the centre of the plain was ideal for controlling the Ganga valley.
2. The Shishunaga Dynasty (शिशुनाग वंश)
| Ruler | Achievement |
|---|---|
| Shishunaga | Destroyed the Pradyota dynasty of Avanti, ending the long Magadha–Avanti rivalry; Avanti became part of Magadha. Buddhist sources link him with Vaishali, used as a capital or secondary capital |
| Kalashoka (Kakavarna) | Held the Second Buddhist Council at Vaishali (about 100 years after the Buddha’s death; often dated c. 383 BCE), presided over by Sabakami; the capital was settled at Pataliputra |
The Second Council in one line
It met over disputes on monastic discipline (Vinaya), the “ten points” such as storing salt in a horn and eating after midday. The Sangha split into the Sthaviravadins (Theras) and the Mahasanghikas, the first major schism in Buddhism.
3. The Nanda Dynasty (नन्द वंश)
| Point | Detail |
|---|---|
| Founder | Mahapadma Nanda (महापद्म नन्द) |
| Titles in the Puranas | Ekarat (sole sovereign) and Sarvakshatrantaka (destroyer of all Kshatriyas) |
| Background | Sources describe him as of low birth; the Nandas are often called the first non-Kshatriya ruling dynasty of a large north Indian state |
| Extent | Often called the first empire builders of India; Magadhan power reached Kalinga |
| Kalinga evidence | The Hathigumpha inscription of Kharavela (Udayagiri, Odisha) refers to a Nandaraja who had a canal dug in Kalinga and who had carried away a Jina image that Kharavela later brought back |
| Last king | Dhanananda (धननन्द), the contemporary of Alexander; called Agrammes / Xandrames in Greek accounts |
| Reputation | Enormous wealth and a huge army, but unpopular for heavy taxation and low birth (in the sources’ telling) |
| End | Overthrown by Chandragupta Maurya with the help of Chanakya (Kautilya), c. 321 BCE |
Why the Nandas matter in a Mains answer
The Nandas built the treasury, army and tax system that the Mauryas inherited. Greek reports that Alexander’s soldiers refused to advance beyond the Beas partly because they feared the Nanda army show how strong Magadha had become.

M["Magadhan supremacy"]
G["Geography

S["Society
less bound by Vedic orthodoxy,

- Fertile land: the middle Ganga plain, with high rainfall, produced a large rice surplus to tax.
- Strategic capitals: Rajagriha was protected by five hills; Pataliputra sat where the Ganga, Son and Gandak met, a natural water-fort (jaladurga).
- Rivers as highways: the Ganga and its tributaries carried armies and trade, especially after Anga’s port town Champa was taken.
- Elephants: Magadha used elephants on a large scale in war, drawn from the forests to its east.
- Unorthodox society: a mix of Vedic and non-Vedic peoples, less constrained by Brahmanical orthodoxy, readier to accept new rulers (even “low-born” ones like the Nandas) and new faiths.
- Ambitious rulers who combined war, marriage diplomacy and administration.
Mnemonic: 'I FRESH' Magadha
Iron · Fertile land · Rivers · Elephants · Strategic capitals · High-ambition rulers (plus an unorthodox society).
5. Foreign Invasions of the North-West
The Achaemenid (Persian) Conquest
| Point | Detail |
|---|---|
| Ruler | Darius I (c. 522–486 BCE) annexed Gandhara and lands along the Indus, around c. 518 BCE (dated variously) |
| Herodotus | Calls India the 20th satrapy and the richest, paying a large tribute in gold dust |
| Effects | Kharosthi script (written right to left) developed from the Persian chancery’s Aramaic; Persian administrative ideas; some scholars see Persian influence in the polished Mauryan pillars and the style of Ashoka’s proclamations, a view others reject |
Alexander of Macedon (327–325 BCE)
| Point | Detail |
|---|---|
| Entry | Crossed the Hindu Kush in 327 BCE and the Indus in 326 BCE |
| Submission | Ambhi (Omphis), ruler of Taxila, submitted and helped him |
| Battle of the Hydaspes (Jhelum), 326 BCE | Fought Porus (Puru), who lost but was reinstated as a subordinate ruler |
| Turning back | His army refused to cross the Beas (Hyphasis); he returned down the Indus and left India in 325 BCE |
| Death | 323 BCE, at Babylon |
| Effects | Opened land and sea routes (Nearchus sailed from the Indus to the Gulf); Greek settlements in the north-west; weakened small north-western states, easing Chandragupta’s conquest of the region; Greek accounts give fixed dates for Indian history |
The anchor date of Indian chronology
Greek writers name an Indian king Sandrokottos. In 1793, Sir William Jones identified him with Chandragupta Maurya. Because Alexander’s dates are known, this gave Indian history its first secure anchor.
Memory Tricks
Dynasty order: 'Hari Shishu Nand Maurya'
Haryanka → Shishunaga → Nanda → Maurya: “Hari’s child (shishu) is the joy (nand) of the peacock (mayura)”. One tradition derives the name Maurya from the Moriya clan, linked in Buddhist legend with peacocks (mora), which makes the last link easy to remember.
Councils and their kings
1st — Rajagriha — Ajatashatru — Mahakassapa
2nd — Vaishali — Kalashoka — Sabakami
Rule of thumb: R before V, and A before K (alphabetical order matches the chronological order).
Don’t Confuse
| This | vs | That |
|---|---|---|
| Ajatashatru fortified Pataligrama | vs | Udayin founded Pataliputra and moved the capital there |
| Shishunaga destroyed Avanti’s Pradyotas | vs | Bimbisara sent Jivaka to cure Pradyota (friendship, not war) |
| First Buddhist council: Rajagriha, Ajatashatru | vs | Second: Vaishali, Kalashoka |
| Dhanananda (Nanda), Alexander’s contemporary | vs | Chandragupta, who met Seleucus, not Alexander, in war |
| Hydaspes = Jhelum (battle with Porus) | vs | Hyphasis = Beas (where the army refused to go on) |
| Darius I (Persian, c. 518 BCE) | vs | Alexander (Macedonian, 326 BCE) |
Common Mistakes
MCQ traps
- “Ajatashatru founded Pataliputra.” He built the fort at Pataligrama. Udayin founded the city and made it the capital.
- “The Second Buddhist Council was held at Pataliputra.” It was at Vaishali. The Third was at Pataliputra (under Ashoka).
- “Alexander fought the Nandas.” He never reached Magadha. His army turned back at the Beas.
- “Porus was killed / imprisoned.” Alexander reinstated him.
- “Kharosthi comes from Brahmi.” It is derived from Aramaic and written right to left.
- “Mahapadma Nanda is called Sarvakshatrantaka in the Arthashastra.” The title comes from the Puranas.
Practice
All questions below are original practice questions written in CGPSC style. They are not previous-year questions.
Level 1: Foundation
- The ruler who founded Pataliputra was ______.
- The Second Buddhist Council was held at ______ under King ______.
- The battle between Alexander and Porus was fought on the banks of the ______.
Answers
- Udayin (Haryanka dynasty).
- Vaishali, under Kalashoka.
- Hydaspes (Jhelum), 326 BCE.
Level 2: Prelims MCQs
Q1. Arrange the following rulers of Magadha in chronological order:
- Kalashoka
- Bimbisara
- Mahapadma Nanda
- Udayin
- (a) 2, 4, 1, 3
- (b) 2, 1, 4, 3
- (c) 4, 2, 1, 3
- (d) 2, 4, 3, 1
Answer and explanation
(a) 2, 4, 1, 3. Bimbisara and Udayin are Haryankas (Bimbisara first), Kalashoka is a Shishunaga, and Mahapadma Nanda founded the Nanda dynasty.
Q2. Consider the following statements:
- Bimbisara annexed Anga.
- Ajatashatru presided over the First Buddhist Council at Rajagriha.
- Shishunaga ended the Pradyota dynasty of Avanti.
Which of the statements given above is/are correct?
- (a) 1 and 2 only
- (b) 2 and 3 only
- (c) 1 and 3 only
- (d) 1, 2 and 3
Answer and explanation
(c) 1 and 3 only. Ajatashatru was the patron of the First Council. It was presided over by Mahakassapa, a monk. “Patron” versus “president” is a standard trap.
Q3. Match List I with List II:
| List I | List II |
|---|---|
| A. Hathigumpha inscription | 1. Twentieth satrapy |
| B. Herodotus | 2. Nandaraja |
| C. Hyphasis | 3. Beas |
| D. William Jones | 4. Sandrokottos |
- (a) A-1, B-2, C-3, D-4
- (b) A-2, B-1, C-4, D-3
- (c) A-2, B-1, C-3, D-4
- (d) A-4, B-1, C-3, D-2
Answer and explanation
(c) A-2, B-1, C-3, D-4. Kharavela’s Hathigumpha inscription mentions a Nandaraja; Herodotus calls India the twentieth satrapy of Persia; the Hyphasis is the Beas; William Jones identified Sandrokottos with Chandragupta Maurya (1793).
Q4. Which of the following was not a reason for the rise of Magadha?
- (a) Nearby deposits of iron ore
- (b) Capitals protected by hills and rivers
- (c) Use of elephants in warfare
- (d) Control of the sea ports of the western coast
Answer and explanation
(d). Magadha’s strength lay in the middle Ganga plain, its iron, its river routes and its elephants. It had no hold on western coastal ports in this period. Its trade outlet was eastwards, through Champa and the Ganga.
Level 3: Mains Answer Writing
Q1. (150–200 words) Examine the factors responsible for the rise of Magadha as the most powerful Mahajanapada.
Model answer outline
- Intro: Of the four great monarchies of the 6th century BCE, Magadha absorbed the rest within about two centuries and became the base of the first pan-Indian empire.
- Body:
- Geography: fertile alluvium; high rainfall; rice surplus.
- Resources: iron deposits close by; elephants from eastern forests.
- Strategic capitals: Rajagriha (five hills), Pataliputra (river confluence, water-fort).
- Communications: the Ganga as a highway; Champa as a trade outlet after Anga’s annexation.
- Rulers and methods: Bimbisara’s marriage diplomacy, Ajatashatru’s conquest of Kosala and Vajji with new war machines, Shishunaga’s conquest of Avanti, the Nandas’ treasury and army.
- Society: less orthodox, open to new faiths and to rulers of non-Kshatriya origin.
- Conclusion: Natural advantages combined with able, ruthless leadership; the Mauryas inherited a ready-made core.
Q2. (60 words) What were the effects of Alexander’s invasion on India?
Model answer outline
- Short-lived politically; no lasting Macedonian rule.
- Weakened the small north-western states, which helped Chandragupta unify the region.
- Opened land and sea routes; Greek settlements in the north-west.
- Greek accounts provide fixed dates (Sandrokottos = Chandragupta), the anchor of ancient Indian chronology.
