Persian and Greek invasions, and the rise of Magadha, 6th century BCE to 321 BCE

The word Hindu first appears, written as Hidus, in the Persian inscriptions of Darius I at Persepolis and Naqsh e Rustam.
In the inscriptions at Persepolis and Naqsh e Rustam, Hidus was a geographical term for the region and people of the Indus valley.
The historians and geographers who came with Alexander described the conditions prevailing in India, praising for example the carpentry of its chariots, boats and ships.
Greek accounts give an outside description of the Indian northwest at a crucial moment, which is their value as a historical source.
Buddhist tradition records the councils held under Magadha's rulers, the first Buddhist council being held at Rajagriha under Ajatashatru.
The second Buddhist council was held at Vaishali under Kalashoka, and the sources of the previous theme apply to Magadha as well.

The Achaemenid rulers who matter are Cyrus II, the founder of the empire, followed by Cambyses II, Darius I and Xerxes I.
Among them Darius I matters most for India, because under him the northwest of the subcontinent was brought into the Persian empire.
In the Punjab the northwest was politically fragmented, with Ambhi of Taxila choosing diplomacy and Porus choosing resistance against Alexander.
Bimbisara of Magadha made a marriage alliance with Kosala Devi, daughter of the king of Kosala and sister of Prasenajit.
He also married Chellana, a Licchavi princess and the mother of Ajatashatru, and made an alliance with the Madra clan of Punjab.

The Achaemenid Empire of Persia rose in the sixth century BCE, but its control never reached deep into the Gangetic heartland, remaining mainly a northwestern phenomenon.
Under Darius I, Gandhara became a satrapy and the Indian borderlands a province often called Hindush in Achaemenid usage.
In Old Persian usage the initial s often shifted, so Sindhu, the Indus, became Hindu or Hindush, and Greek forms later gave Indos and India.
Persian contact brought Persian and Aramaic into political communication in the northwest, and later Greek and Aramaic were known in Afghanistan and likely understood at Taxila.
Greek and Persian rivalry was the background to Alexander's march, and Darius I was defeated by the Greeks at Marathon in 490 BCE.
Alexander III of Macedon (336 to 323 BCE), Sikander in Persian accounts, marched into the northwest as the final stage of the Macedonian conquest of Persia.
In 327 to 326 BCE Alexander crossed the Indus near Attock and entered Taxila, whose ruler Ambhi welcomed him.
Porus, who ruled between the Hydaspes (Jhelum) and the Acesines (Chenab), fought Alexander in 326 BCE, lost, and was given back his kingdom as satrap.
After the battle with Porus, Alexander's tired soldiers turned back without attacking the Nanda ruler Dhana Nanda, and the march into India ended there.
This was the first direct contact between India and Europe, and it opened a direct India Hellenistic connection that mattered for later Indo Greek developments.
The campaign also showed the role of cavalry, mobility and organised command in warfare, and widened the subcontinent's diplomatic and commercial horizon.
After Alexander's death, Hellenistic zones stayed strongest in Afghanistan, Gandhara and northwest Pakistan, and Greek possessions were later lost to the Mauryan empire.

Persian	Cultural and linguistic contact	Persian and Aramaic entered political communication in the northwest; later Greek and Aramaic were known in Afghanistan and likely understood at Taxila
Persian	Opening of routes	Imperial roads, tribute and long distance exchange tied the northwest more firmly to West Asia
Greek	A direct India Hellenistic connection	It mattered greatly for later Indo Greek developments
Greek	Military lessons	The role of cavalry, mobility and organised command in warfare
Greek	Diplomatic and commercial links	The western horizon of the subcontinent widened
Greek	Historical source value	An outside description of the Indian northwest at a crucial moment

The middle Gangetic plain gave Magadha fertile alluvial land, which supported strong agriculture and a surplus of production.
A river advantage placed Magadha well to control the communication and trade that moved along the Ganga system.
The wider region lay near forest resources, elephants and the iron rich zones of eastern India, giving Magadha access to them.
Magadha's success is closely tied to ambitious and strong rulers such as Bimbisara and Ajatashatru of the Haryanka dynasty.
Through aggressive expansion Magadha conquered Anga, fought the Vrijjis, and outlasted rival powers such as Kosala and Avanti.
Rajagriha was a defensible capital, and later Pataliputra was even better placed for imperial expansion because of its riverine location.

Bimbisara
Haryanka, 544 to 492 BCE
- Considered the founder of the Haryanka dynasty, Bimbisara was a contemporary of the Buddha and Mahavira.
- He kept a standing army and was the first ruler to make marriage alliances to strengthen his kingdom.

- He won Kashi from Kosala and Vaishali from the Licchavis, extending the kingdom of Magadha.
Udayin
Haryanka, 460 to 444 BCE
- Udayin moved the capital of Magadha to Pataliputra, whose riverine location made it better placed for imperial expansion.
Shishunaga
Shishunaga dynasty, 412 to 344 BCE
- A minister under Nagadasaka, the last Haryanka ruler, Shishunaga killed him and founded his own dynasty in Magadha.
- He destroyed the power of Avanti, ending a century old rivalry between Magadha and the Avanti kingdom.

Achaemenid Empire: The Persian Empire relevant to Indian history, which rose in the sixth century BCE and became one of the largest of the ancient world.
Satrap: A governor of a province of the Persian Empire; Alexander also reinstated Porus as satrap.
Satrapy: A province of the Persian Empire governed by a satrap; Gandhara became one under Darius I.
Hindush: The province connected with India in Achaemenid usage, from Sindhu, the Indus.
Hellenistic: Of Greek history, art and culture, as in the Hellenistic zones left in Afghanistan, Gandhara and northwest Pakistan.
Hydaspes: The Greek name of the Jhelum, where Porus fought Alexander in 326 BCE.
Acesines: The Greek name of the Chenab.
Ekarat: The sole sovereign, the title Mahapadma Nanda took.
Rathamusala: A scythed or maced chariot, of which Ajatashatru is the presumed inventor.
Mahashilakantaka: An engine to throw big stones, of which Ajatashatru is the presumed inventor.
Patricide: The killing of one's father, as Ajatashatru killed Bimbisara, a rare case in ancient India.

In the northwest, Persian rule had connected the frontier to West Asia, and Alexander had then destroyed Persian power there.
After Alexander's death Macedonian authority in the region was unstable, and the Greek ruled satrapies and frontier garrisons were vulnerable.
In the Gangetic heartland, Magadha was already the strongest Indian power by the late fourth century BCE.
The Haryankas, Shishunagas and Nandas had built a strong state, with resources, taxation, river control and military organisation already in place.
This is the landscape into which Chandragupta Maurya emerged; tradition connects him with Taxila and Kautilya, and his empire is the next theme.
