Hello Dear,

The factors that contributed to the rise of Magadha were the strategic locations of its two capitals Rajagriha and Pataliputra, very rich alluvial soil contributing to agricultural surplus production, and the availability of minerals, which resulted in the introduction of iron tools especially for warfare. Magadha was strategically located. The capital of Magadha, Rajgriha was surrounded by 5 hills which made it difficult to be conquered. Pataliputra, it's later capital was also strategically located at the confluence of the Ganges, the Gond and the Sone and therefore, formed a water fort or a jaldugra.

Good Luck
