Reasons for Magadha’s success
- Advantageous geographical position:
- Magadha’s strategic location provided its proximity to the rich iron deposits. Magadhan Army had the high-quality weapon
- Its capital Rajagriha: surrounded by 5 hills – provided a natural fortification
- Patliputra: On the confluence of Rivers Ganga and Son: provided route for trade and commerce
- Ganga plains provided rich ground for agriculture to feed its standing Army
- Used Elephants on large scale: Unlike horses (used by Magadha’s rivals), Elephants can be used for storming fortresses and marching over areas lacking roads
- Good leaders: E.g. Bimbisara, Ajatashatru, Mahapadma Nanda
- Enthusiasm for expansion: Magadhan society support for unorthodox religion led to the quest for expansion to other areas

Persian Invasion in India

In India’s North-west, the three Mahajanapadas of Kamboja, Madra, and Gandhara were continuously fighting with each other (there was no central authority as Magadha in the East). Taking advantage of political instability, the Persian Empire in the 6th century penetrated northwestern India. All Indian tribes west of the Indus River submitted to him and paid tribute.
Impact of the Persian Invasion:
- The impetus to Indo-Persian trade and commerce
- Persian Sigloi-type coins were copied in India
- The use of Kharoshti script (a form of Persian writing) became popular in India’s north-west
- Few of Ashoka’s edicts were also written in Kharoshti script.
Influenced Mauryan art e.g. the monolithic pillars of Ashoka and sculptures carved on them esp. bell-shaped capitals and preambles of Ashoka’s Edict have a lot of Iranian Influence
Macedonian (Greek) Invasion in India
Alexander’s Invasion (326BC): Alexander (356-323 BC) after defeating Persian ruler Darius, captured most of North-West India. All the Kings submitted to him except for Porus who fought the battle of Hydaspas (near Jhelum River). His Armies were exhausted of battles and didn’t cross River Beas. On the Way to Greece, he died in Babylonia (323 BC)
Impact of Alexander’s Invasion to India:
- Established direct contact between India and Greece: Writings of Greek Historians provide an invaluable source of information for Indian historical events
- Greek merchants and craftsmen started trading with India
- Established Gandhara school of arts
- Exposed India to Invasion from the west: By opening four lines of communication (three routes by land and one by sea)
- Unification of North India under Chandragupta Maurya: Alexander’s Invasion destroyed smaller states and thus aided Mauryan Empire’s expansion to the north-west.
