About the Mahajanapadas and the Rise of Magadha
By the 6th century BC, the small tribal settlements of the Later Vedic period had grown into larger territorial states. These states are called the Mahajanapadas (‘maha’ means great and ‘janapada’ means the land of a people). The list of sixteen Mahajanapadas is found in the Buddhist text Anguttara Nikaya and in the Jain text Bhagavati Sutra. They were Kashi, Kosala, Anga, Magadha, Vajji, Malla, Chedi, Vatsa, Kuru, Panchala, Matsya, Surasena, Assaka (Ashmaka), Avanti, Gandhara and Kamboja. Some of these were monarchies, while others, such as Vajji and Malla, were gana-sanghas or republics.
Among the Mahajanapadas, Magadha emerged as the most powerful. Its rise had several causes. Its geography was favourable: it lay in the fertile Ganga valley, was protected by rivers and hills, and had easy access to iron ore for weapons and tools. It had a large number of elephants, which were useful in war, and its rulers were ambitious and able. Rivers helped trade and transport. Its first capital was Rajgriha (Girivraja), and later the capital was shifted to Pataliputra.
The first great dynasty of Magadha was the Haryanka dynasty. Its founder is regarded as Bimbisara (c. 544–492 BC), the first important ruler of Magadha. He expanded his kingdom by marriage alliances: he married Kosala Devi, the daughter of the king of Kosala, Chellana, a Lichchhavi princess of Vaishali, and Kshema, a princess of Madra. He also annexed Anga and sent his physician Jivaka to the king of Avanti, Chanda Pradyota. Bimbisara was later killed by his son Ajatashatru (c. 492–460 BC). Ajatashatru fought against Kosala and against the Vajji (Lichchhavis), using two new weapons, the mahashilakantaka (a stone-throwing device) and the rathamusala (a chariot with blades). He built the fort of Pataligrama, which grew into Pataliputra. The First Buddhist Council was held at Rajgriha in 483 BC under his patronage. His son Udayin shifted the capital from Rajgriha to Pataliputra.
The Haryankas were followed by the Shishunaga dynasty. Its ruler Shishunaga destroyed the power of Avanti and brought an end to the rivalry between Magadha and Avanti. Under his successor Kalashoka, the Second Buddhist Council was held at Vaishali in 383 BC. The last important dynasty before the Mauryas was the Nanda dynasty. Its founder, Mahapadma Nanda, is often called the first historical emperor of India and is said to have destroyed the Kshatriya dynasties; he was also called ekarat (the sole sovereign). The last Nanda ruler was Dhana Nanda, who was a contemporary of Alexander the Great, whose invasion of India took place in 326 BC. Around 321 BC, Chandragupta Maurya, with the help of Chanakya (Kautilya), overthrew Dhana Nanda and founded the Mauryan Empire. Thus the story of the Mahajanapadas ends with the rise of Magadha and the beginning of the first great empire of India.

Why the Mahajanapadas and Magadha Matter for Exams
This topic connects the end of the Vedic age with the beginning of the Mauryan Empire, so it is asked frequently. Common questions include: How many Mahajanapadas were there? (sixteen.) Which text lists them? (Anguttara Nikaya.) Which Mahajanapada was a republic? (Vajji.) Which was the most powerful Mahajanapada? (Magadha.) What was the first capital of Magadha? (Rajgriha.) Who was the first important ruler of Magadha? (Bimbisara.) Who killed Bimbisara? (Ajatashatru.) Where was the First Buddhist Council held? (Rajgriha, 483 BC.) Who destroyed Avanti? (Shishunaga.) Who was the first historical emperor of India? (Mahapadma Nanda.) A frequent trap is to confuse the First Buddhist Council (Rajgriha, 483 BC) with the Second (Vaishali, 383 BC). Another trap is to think that Bimbisara founded the Mauryan Empire; in fact it was founded by Chandragupta Maurya. Students should also remember that Pataliputra became the capital under Udayin, not under Bimbisara.
