The c. 600 BCE turning point and the sources

Detail

Why the sixth century BCE is the "watershed"

• Historians treat the sixth century BCE as the great dividing line in early Indian history. Several big changes cluster together in this one period.
• What changes at once:
• Early states appear — the mahajanapadas, the first large kingdoms and republics.
• Cities appear — this is called the second urbanisation (the first was the Harappan one).
• Iron use grows wider — more iron tools, more iron weapons.
• Coinage develops — money begins to be used in exchange.

• Buddhism and Jainism are born in the same window.

• For an economy note, the point is simple: states + cities + iron + coins together create surplus farming, market exchange and craft groups. None of the four alone would do it.

The south and central Indian side: megaliths

• In central and south India, the first millennium BCE brings megaliths (large stone burial structures marking graves).
• The dead were buried with a rich range of iron tools and weapons. So iron was not a northern monopoly — the south had its own iron-using societies at the same time.
• Adichanallur (Tamil Nadu) is one such burial site excavated by the ASI and published as a full excavation report. [4]

The archaeological register — reading the pots

• Archaeologists date and rank these societies by pottery types found in dig layers. Two pottery names matter for this section.
• PGW — Painted Grey Ware:
• First-millennium BCE Ganga settlements show iron implements, a wider variety of grains, and PGW.
• PGW is called the earliest pottery of the Iron Age in this region. It was first noticed in the lowest levels of Ahichchhatra (Bareilly district) in 1940–44, but its importance was not understood then. [3]
• In 1950–52, the excavation at Hastinapura (Meerut district) gave, for the first time, a cultural index (a fixed ladder of layers used to date other sites) for the upper Ganga basin. [3][5]

• The PGW phase is usually dated c. 1200–800 BCE, and PGW settlements spread east into the Ganga–Yamuna valleys — the same spread that by the second quarter of the first millennium BCE produced the first cities. [2][3]

• NBPW — Northern Black Polished Ware:

• Comes after PGW, in the middle Ganga region — roughly Prayagraj to eastern Bihar.
• It is a glossy black "deluxe ware" — fine, shiny, expensive pottery. Its arrival marks a richer material culture: more wealth, more specialised craft, more people who can afford fine goods.
• NBPW generally starts around the 6th century BCE — the same watershed date. [2]
• NBPW appears from the earliest levels at Ahichchhatra, Sonkh, Atranjikhera, Noh, Ropar and Sravasti. [2]
• At Old Rajagir (Bihar), real occupation of the site begins only when NBPW appears; the early NBPW layers also gave a new burial type — half-oval pits with cremated bone bits and ash. [2]

The sources for economic history — and what each one hides

• Inscriptions (epigraphy)
• Two main kinds: votive records (gifts recorded by donors) and land-grant copper plates.
• Strength: they are virtually permanent — metal and stone survive.

• Weakness: they record grand and unique events, written from the commissioner's point of view (the person who paid for the record). They never describe routine agriculture or daily life. So a farmer's normal year leaves no inscription.

• Texts

• Jatakas — stories in Pali, written down in the middle of the first millennium CE from older oral tales. Full of merchants, caravans, debt and village life.
• Arthashastra — a manual on state, revenue and administration.
• Sangam poems — the south Indian window on trade, ports and chiefs.
• Banabhatta's Harshacharita — c. 7th century CE.

• The Periplus — a Greek sailing and trading handbook for the Indian Ocean.

• Coins (numismatics) — the study of coins. Coins date layers, show which rulers issued money, and show how far trade reached when a coin turns up far from its mint.

• Excavation
• The big practical block: many early historic cities are still inhabited today. You cannot dig under a living town, so the evidence stays buried.
• Where digging is possible, the ASI publishes formal excavation memoirs — for example Memoirs of the ASI No. 113, Excavations at Hulas. [6]

Putting it together for the exam

• Each source has a blind spot. Inscriptions skip the ordinary; texts are written by elites and copied late; coins tell circulation but not who farmed. Historians therefore cross-check all four — text, inscription, coin and dig layer.
• Pottery is the neutral witness. PGW and NBPW do not flatter a king. That is why the 600 BCE turning point rests so heavily on them.

Prelims Hooks

• Sixth century BCE = watershed: mahajanapadas, cities, wider iron use, coinage, Buddhism and Jainism.
• PGW = Painted Grey Ware, earliest Iron Age pottery of the region; phase dated c. 1200–800 BCE. [2][3]
• PGW first noticed at Ahichchhatra (Bareilly district) in 1940–44. [3]
• Hastinapura (Meerut district), excavated 1950–52, gave the first cultural index for the upper Ganga basin. [3][5]
• NBPW = Northern Black Polished Ware, glossy black "deluxe ware"; starts around the 6th century BCE. [2]
• NBPW core zone = middle Ganga, Prayagraj to eastern Bihar; also at Sonkh, Atranjikhera, Noh, Ropar, Sravasti. [2]
• At Old Rajagir, real occupation begins only with the NBPW phase. [2]
• Megaliths of central and south India = first millennium BCE burials with iron tools and weapons; Adichanallur is an ASI-excavated example. [4]
• Land-grant copper plates and votive records are the two inscription types; both record grand events, never routine farming.
• Harshacharita by Banabhatta, c. 7th century CE; Jatakas in Pali, written down mid-first millennium CE.

Mains Points

• The 600 BCE turning point is a package, not a single cause. Iron raised farm output; surplus fed towns; towns needed exchange, so coins spread; kingdoms taxed the surplus. Answers that credit iron alone are weak — the NBPW "deluxe ware" evidence shows the change was as much about wealth and craft specialisation as about tools. [2]
• Source bias shapes what we can say about the economy. Inscriptions speak for donors and kings, not cultivators. So most of what we know about ordinary agriculture comes from archaeology (grain remains, tools, pottery) and from incidental detail in the Jatakas — not from official records.
• North–south simultaneity. The Ganga valley (PGW → NBPW) and peninsular India (megaliths with iron grave goods) both enter the iron-using phase in the first millennium BCE. Early Indian economic change was not a single northern story radiating outward. [4]
• Archaeology has a built-in limit. Because early historic cities are still lived in, our urban sample is skewed towards sites that were abandoned. Any claim about the scale of the second urbanisation is therefore a minimum, not a total.
