In ancient times Magadha was an important city of India because it was the centre of cultural change. The kings who ruled Magadha in the 7th century BC were enterprising. It was the seat of the Brihadratha dynasty, Pradyota dynasty, Shishunaga dynasty, Nanda Dynasty, Maurya Empire, Shunga Dynasty, Kanva Dynasty and the Gupta dynasty. Magadha formed one of the sixteen Mahajanapadas or regions in ancient India. Magadha covers the portion of Bihar lying south of the Ganges, with its capital at Rajgir. With the conquest of Licchavi and Anga, the kingdom of Magadha expanded to include Bihar and Bengal. The capital of Magadha was Rajgriha but in the later ages the capital of Magadha was Pataliputra. Location of Magadha Magadha was situated in the eastern division of the nine portions into which the sub-continent of India was divided. Magadha was bounded by the Ganges on the north, by the district of Varanasi on the west, by Hiranyaparvata or Monghyr on the east, and by Kirana Supavana or Singhbhum on the south. Magadha was a narrow strip of country of some considerable length from north to south, and of an area greater than that of Kosala. Just as Kosala corresponded very nearly to the present province of Oudh, but was somewhat larger, so Magadha corresponded at the time of Lord Buddha to the modern district of Patna, but with the addition of the northern half of the modern district of Gaya. The inhabitants of this region used to call it Maga, a name doubtless derived from Magadha.
Several reasons account for the rise and growth of the Magadhan Empire, in the first place the emperors who ascended the throne of Magadha from the time of Bimbisara were mostly conquerors. This policy of conquest continued till the time of the Kalinga war under Asoka's regime. Secondly, many emperors of Magadha extended the empire not merely by conquest. They acquired territories by matrimonial alliances. For example, Bimbisara, his son Ajatasatru and others obtained territories through matrimonial relationship. This was one of the important factors that led to the expansion of Magadha. Thirdly, Magadha had other advantages too. Geographically, it was located in a position where their had been richest iron deposits. With the help of iron Magadha could produce weapons for war. Also iron implements were helpfii) to increase agricultural products. Fourthly, the capital of Magadha, first at Rajgir and then shifted to Pataliputra were both situated at very strategic points. It was difficult for the invaders to do any harm to the Magadha and its capital Fifthly, the military organization of Magadha was also very strong. The largescale use of elephants was helpful in storming fortresses. Sixthly, it has been pointed out by Professor R.S.Shanna that the unorthodox character of the Magadhan society showed much enthusiasm for expansion. These are the reasons why Magadha was successful in building up an empire. Brihadratha has been referred to in the Mahabharata as the founder of the kingdom of Magadha. But historically Bimbisara is known to be the first important king of Magadha.
Magadha was an ancient kingdom of India, situated in what is now west-central Bihar state, in northeastern India along the valley of the Ganges River. Its Nanda Dynasty (c. 420 to 320 BC) spread across northen India and led to the Maurya Empire, which covered most of modern-day India, Pakistan, and part of Persia by 300 BC.
The Kingdom of Magadha lasted for about 179 years, from 500 BC to 321 BC.
