Introduction
The Mauryan Empire was founded by Chandragupta Maurya. He founded his line of rule out of the last king of Nanda dynasty. He rose to power in about 321 BC. The line of the Mauryan rule was broken in 185 BC when Shungas overpowered them.
Mauryan Empire was the first major kingdom that emerged in Magadha, that spread its rule over large parts of the subcontinent. It is the first Empire in Indian history that had an elaborate administrative system, a large standing military and most features of a centralized state.
It is during the rule of Chandragupta Maurya that Kautilya wrote Arthasastra – the treatise on statecraft of the Mauryan Empire.

Rise of Magadha
In the beginning of the 6th century BC, northern India consisted of a large number of independent kingdoms which were large states (also known as Mahajanapadas).
The Buddhist literature Anguttara Nikaya gives a list of sixteen kingdoms called Sixteen Mahajanapadas. These were:
Anga, Magadha, Kasi, Kosala, Vajji, Malla, Chedi, Vatsa, Kuru, Panchala, Matsya, Surasena, Asmaka, Avanti, Gandhara and Kambhoja.
Then, from 6th to 4th century BC, Indian political history went through a period of struggle. During this time, four kingdoms – Magadha, Kosala, Vatsa and Avanti – struggled for dominance among themselves.
In the end, Magadha triumphed and arose as the most powerful and prosperous kingdom in North India.
Reasons for the Rise of Magadha
It was advanced in military organization and was the first Indian state to use elephants on a large scale in war.
It had a favourable geographical location and was situated near the richest iron deposits.
It had an immensely fertile soil since it was at the centre of the middle Gangetic plains.
Both of its capitals, Rajagriha and later Pataliputra, had a geographical advantage.
Rajgir was surrounded by hills and could not be seized.
Pataliputra was surrounded by rivers and therefore remained secure from siege.
The society of Magadha was of unorthodox character. It was racially mixed and was enthusiastic about expansion of the kingdom.
Dynasties and Kings of Magadha
It is during the reign of Bimbisara that Magadha rose to power and prominence. Bimbisara began his expansion of Magadha by defeating the neighbouring kingdom of Anga. He belonged to Haryanka clan.
Thus, Haryanka dynasty was the first to rule Magadha. This was followed by Shishunagas and Nandas.
