In the sixth country B.C. North India was divided into sixteen kingdoms out of which Avanti, Vatsa, Kosala and Magadha rose into prominence by aggrandizing upon other weaker states.These four states involved themselves in internecine quarrel in which Magadha emerged as the most powerful state and acquired mastery in the political domain of India.
Magadha under Bimbisara:
Magadha rose into prominence under the rule of Bimbisara who belonged to the Haryanka dynasty. Most probably he overthrew the Brihadrathas from Magadha and assumed the title “Srinika” after his accession. He ruled Magadha from 544 B.C. to 493 B.C. His greatest achievement was the establishment of Magadhan empire. He followed fourfold policy in order to fulfill his programme of imperial expansion.
Policy of Matrimonial Alliance:
By adopting the policy of matrimonial alliance, Bimbisara tried to augment his power. He married Kosaladevi, daughter of king Mahakosala of Kosala, received the Kasi village as dowry, which yielded revenue of 1, 00,000. “Mahavamsa” mentions his marriage with Chellana the daughter of Chetak, the Lichchavi chief of Vaisali.
He then married Vasavi, a princess of Videha in the northward. He also got the hand of Khema, the daughter of king of Modra in Central Punjab. The establishment of matrimonial relations with these states added glory to the Magadhna empire and it also paved the way for the expansion of Magadhan empire and westward.
Policy of Conquest:
The next policy of Bimbisara for the expansion of Magadhan empire was the policy of conquest. Bimbisara led a campaign against the kingdom of Anga and defeated its king Brahmadatta. Anga along with its capital city Champa, was annexed to the Magadhan empire.
Friendly Relation with distant Neighbours:
As a farsighted diplomat, Bimbisara had followed the policy of friendship towards the distant neighbours to win their co-operation for the safety and security of his empire. He received an embassy and letter from Pukkusati, the ruler of Gandhar with which Pradyota had fought unsuccessfully. Magadha’s most formidable enemy was Chanda Pradyota Mahasena of Avanti who fought with Bimbisara but ultimately the two thought it wise to become friends. He also sent his physician Jivak to Ujjain when Pradyota was attacked by jaundice.
Consolidation of his Empire by a Good Administrative System:
By introducing a highly efficient system of administration, Bimbisara consolidated his conquests. His administration was found to have been really well-organised and efficient. The high officers were divided into three classes, viz. executive, military and judicial. The ‘Sabarthakas’ were responsible for the management of general administration.
“Senanayaka Mahamatras” were in charge of military affairs. “Vyavaharika Mahamatra’s” were in charge of judicial-administration. Provincial administration was also well-organised. The head of provincial administration was “Uparaja”. The villages enjoyed rural autonomy. “Gramika” was the head of the village administration. The penal laws were severe. Bimbisara also developed the means of communication by constructing good roads. He is said to have established a new capital at Rajagriha situated on the outskirts of the old capital Girivraja.
He made Magadha a paramount power in the sixth century B.C. It is said that his kingdom had consisted of 80,000 villages. He was also a devotee of Buddha. He donated a garden named “Belubana” to the Buddhist Sangha. According to the Buddhist chronicle Bimbisara ruled Magadha from 544 B.C. to 493 B.C. He was succeeded by his son Ajatasatru who had killed him and seized the throne for himself.
Ajatasatru
The reign of Ajatasatru witnessed the high watermark of Bimbisara dynasty. From the very beginning Ajatasatru pursued the policy of expansion and conquest. He began a prolonged war with Prasenjit of Kosala who had revoked the gift of the Kasi village made to Bimbisara. The war continued for some time with varying success to both sides till Prasenjit ended it by giving his daughter, Vajira Kumari in marriage to Ajatasatru and leaving him in possession of Kasi.
The next achievement of Ajatasatru was the conquest of Lichchavis of Vaisali. Chetak, chief of Lichchavis had formed a strong confederacy comprising 36 republics in order to fight Magadha. According to jaina sources, before his death, Bimbisara gave his elephant “Seyanaga” “Sechanaka” and two large bejewelled necklaces, one each to his sons Halla and Vehalla who were born of their Lichahhavi mother, Chellana.
Chetak had given them political assylum. After his accession, Ajatasatru requested chetak to surrender them. But Chetak refused to extradite Chetaka’s step brothers. So the conflict between Ajatasatru and Lichchhavis became inevitable.
According to Buddhist text Ajatasatru had entered into an agreement with Lichchhavis to divide among them the gems extracted from a mine at
