The Magadha Empire was the most powerful Kingdom in Ancient India. It had powerful kings like Bimbisara, Ajatasatru, Dhana Nanda, Chandragupta Maurya, etc.
This rise of Magadha Imperialism is unique in Indian history. The political history of India from the earliest times till the present day is an endless story of struggle between the forces of centralization and decentralization.
In the sixth century B.C., India presented the chronic symptom of disintegration. The Aryan India in the North was divided into, sixteen great kingdoms and a number of republican, autonomous states.
Out of the medley of political atoms, four kingdoms viz., Avanti, Vatsa, Kosala and Magadha, Magadha Empire rose into prominence by aggrandizing upon other weaker states. They entered into a four-power conflict for imperial supremacy which ended in the ultimate victory of Magadha Kingdom over them. It is the first successful attempt for imperial and dynastic unification of India in the period of recorded history.
One of the main factors behind the rise of Magadhan Power was her economic solvency and growing prosperity. Magadha had a vast population which could be employed in agriculture, mining and for manning her army. The Sudras and the non-Aryans could be employed in clearing up the forest and reclaim surplus land for farming. The surplus population could easily live on the yield of the surplus land. The Magadhan lands were very fertile due to its location between the Ganges and the Son. In the 4th Century B.C. that the Magadhan lands yielded multiple crops round the year. People of Magadhan Empire became prosperous due to fertility of the land and the government became automatically rich and powerful.
