Ancient Indian History
🔒 Log in to trackMahajanapadas & Rise of Magadha
🔒 Log in to trackBy the 6th century BCE north India had sixteen big states called mahajanapadas. Magadha beat the rest and grew into an empire under the Haryanka, Shishunaga and Nanda dynasties. Persian and Greek invaders entered the north-west in the same age. Exams ask for capitals, rulers in order, and the two invasions.
The sixteen states
The Buddhist text Anguttara Nikaya lists 16 mahajanapadas. The Jain Bhagavati Sutra gives a slightly different list.
| Mahajanapada | Capital | Note |
|---|---|---|
| Magadha | Girivraja (Rajagriha), later Pataliputra | Became the empire |
| Anga | Champa | Annexed by Bimbisara |
| Kashi | Varanasi | Absorbed by Kosala and Magadha |
| Kosala | Shravasti (also Ayodhya) | Eastern UP |
| Vajji | Vaishali | Republic of 8 clans, including Licchavis |
| Malla | Kushinara, Pava | Republic |
| Chedi | Shuktimati | Bundelkhand |
| Vatsa | Kaushambi | Near Prayagraj |
| Kuru | Indraprastha | Delhi-Meerut area |
| Panchala | Ahichchhatra, Kampilya | Western UP |
| Matsya | Viratnagar | Jaipur-Alwar area |
| Surasena | Mathura | UP |
| Assaka | Potana | Only one south of the Vindhyas |
| Avanti | Ujjain (north), Mahishmati (south) | Malwa |
| Gandhara | Taxila | North-west |
| Kamboja | Rajapura | Known for horses |
Tip: Learn six pairs first: Avanti-Ujjain, Vatsa-Kaushambi, Kosala-Shravasti, Anga-Champa, Gandhara-Taxila, Matsya-Viratnagar.
Vajji and Malla were republics. The others were kingdoms.
Why Magadha won
Four states were the strongest: Magadha, Kosala, Vatsa and Avanti. Magadha won because it had:
- Iron mines for weapons and ploughs.
- The rich Ganga plain.
- Elephants for its army.
- Natural forts at Rajagriha.
The rulers in order
| Dynasty | Rulers and events |
|---|---|
| Haryanka | Bimbisara: met both Buddha and Mahavira; made marriage alliances; annexed Anga |
| Ajatashatru: killed his father; fought the Vajjis; First Buddhist Council | |
| Udayin: founded Pataliputra at the Ganga-Son meeting point | |
| Shishunaga | Shishunaga: destroyed Avanti |
| Kalashoka: Second Buddhist Council at Vaishali | |
| Nanda | Mahapadma Nanda: first non-Kshatriya empire builder; titles Ekarat and Sarvakshatrantaka |
| Dhana Nanda: last Nanda; met Alexander; overthrown by Chandragupta Maurya |
Watch: Udayin, not Ajatashatru, founded Pataliputra.
The Persians
Darius I took Gandhara and the Punjab about 516 BCE. Persian contact brought the Kharosthi script. It is written right to left.
Alexander
- Alexander invaded in 326 BCE.
- He beat Porus (Puru) at the Hydaspes (Jhelum).
- His tired troops refused to go beyond the Beas (Hyphasis).
- He died at Babylon in 323 BCE.
Watch: The battle was at the Jhelum. The mutiny was at the Beas.
Question types you will see
Each type: how to recognise it, the method step by step, and one question to try.
Mahajanapada and its capital
A capital or state is given with four options, or "which pair is correctly matched".
Recall the six key pairs.
Republics have cities, not royal capitals: Vajji-Vaishali, Malla-Kushinara.
Magadha had two capitals in turn: Rajagriha, then Pataliputra.
Setters pick pairs from the same short list every year.
The capital of the Vatsa mahajanapada was:
Show solutionHide solution
Vatsa is linked with a city near Prayagraj.
That city is Kaushambi.
Kaushambi
Magadhan ruler and event
"Who founded Pataliputra", "under which dynasty was the Second Council held", or an order of rulers.
Recall the chain: Haryanka, Shishunaga, Nanda.
Attach one event to each king: Bimbisara annexed Anga, Ajatashatru beat the Vajjis, Udayin founded Pataliputra.
Shishunaga destroyed Avanti. Kalashoka held the 2nd Council. Mahapadma Nanda was Ekarat.
Each king has one event, so the event names the king.
Who founded Pataliputra at the meeting point of the Ganga and the Son?
Show solutionHide solution
Ajatashatru is the trap option.
The Haryanka successor Udayin founded the city.
Udayin
Source text, republics and odd facts
"The list of 16 mahajanapadas occurs in", "which was a republic", "the only one south of the Vindhyas".
Source: Anguttara Nikaya (Buddhist). The Jain list differs.
Republics: Vajji (with Licchavis) and Malla.
Extremes: Assaka in the south, Kamboja in the north-west with its horses.
Each odd fact points to one state.
The list of sixteen mahajanapadas appears in which Buddhist text?
Show solutionHide solution
The Jain Bhagavati Sutra gives a different list.
The Buddhist list is in the Anguttara Nikaya.

Persian and Alexander's invasions
Darius I, Kharosthi script, the Hydaspes battle, the Beas mutiny.
Darius I, about 516 BCE: Gandhara and west Punjab. He brought Kharosthi.
Alexander, 326 BCE: beat Porus at the Hydaspes (Jhelum).
The troops refused at the Beas (Hyphasis). He died at Babylon in 323 BCE.
Each event has one river, and the rivers are the traps.
Alexander's army refused to march beyond which river?
Show solutionHide solution
The battle with Porus was at the Jhelum.
The refusal came further east, at the Hyphasis.
The Beas (Hyphasis)
Why Magadha rose
"Which factor helped the rise of Magadha" or "which was NOT a reason".
List the reasons: iron mines, Ganga plain, elephants, natural forts.
Cut any option outside this list.
Remember the rival powers: Kosala, Vatsa, Avanti.
The list of reasons is short, so any new item is the wrong option.
Which of these helped Magadha most in its early rise? (a) Iron mines nearby (b) Sea trade with Rome (c) A large navy (d) Silk Road tolls
Show solutionHide solution
Magadha had iron ores in south Bihar.
The other options belong to later or different regions.
(a) Iron mines nearby
Arrange rulers in order
"Arrange in chronological order" with three or four Magadhan kings.
Write the dynasty next to each king.
Order the dynasties: Haryanka, Shishunaga, Nanda.
Inside Haryanka: Bimbisara, Ajatashatru, Udayin.
Placing the dynasty first gives most of the order.
Arrange in order: 1. Mahapadma Nanda 2. Bimbisara 3. Udayin 4. Kalashoka
Show solutionHide solution
Bimbisara and Udayin are Haryanka, with Bimbisara first.
Kalashoka is Shishunaga.
Mahapadma Nanda is Nanda.
2, 3, 4, 1
Shortcuts that save time
Vatsa-Kaushambi and Vajji-Vaishali. Avanti-Ujjain and Anga-Champa. Gandhara-Taxila. Kuru-Indraprastha.
Haryanka, then Shishunaga, then Nanda, then Maurya. Council 1 is Ajatashatru (Haryanka). Council 2 is Kalashoka (Shishunaga).
The Second Buddhist Council was held under which dynasty?
Show solutionHide solution
Kalashoka held it at Vaishali.
Kalashoka belongs to the Shishunaga dynasty.
Shishunaga dynasty
Mistakes to avoid
Where most students lose marks on this subtopic.
Saying Ajatashatru founded Pataliputra.
Udayin founded Pataliputra.
Putting Assaka in the north.
Assaka is the only mahajanapada south of the Vindhyas. Avanti is in Malwa.
Saying Alexander's army mutinied at the Jhelum.
The battle with Porus was at the Jhelum. The mutiny was at the Beas.
Mixing up Vatsa and Kosala capitals.
Vatsa is Kaushambi. Kosala is Shravasti.
