Evolution Period: ~5,300 YA to ~2,450 YA
[3300 BCE to 500 BCE]
Note on “History”:
Consensus: Prehistory becomes history at the moment humans start leaving written records.
Writing lets us hear people from the past in their own words instead of only guessing from tools, bones, and ruins.
Still mixed prehistoric/historic globally
First cities and state societies
Administrative economies, long-distance trade
Bronze metallurgy:
Earlier bronze objects exist, but are rare and experimental.
~3300 BCE (Mesopotamia) + 2600 BCE (Indus): Systematic copper–tin bronze → proper Bronze Age
Writing emerges —
Mesopotamia (Sumerians): ~3200 BCE → often cited as the classic start of history; Cuneiform; administrative accounting; historiography begins. [Today: Core region → Tigris–Euphrates river basin (southern Iraq); Iraq, Eastern Syria, Southeastern Turkey, Western Iran.]
Egypt: ~3100 BCE → Hieroglyphs; inscriptions. [Today: Core region → Nile Valley and Delta; Egypt.]
Indus Valley: ~2600 BCE → script still undeciphered; seals and short inscriptions. [Today: Core region → Indus River system; Pakistan, Northwestern India, Eastern Afghanistan.]
Pre-literate but system-critical regions —
Aegean: ~4000–2000 BCE → Maritime trade zone, metallurgy, redistribution; transition into literate around 1900–1800 BCE with Cretan scripts. [Today: Core region → Cyclades, Crete (Minoan civilization); Greece (especially Crete), Western Turkey (Aegean coast/Anatolia).]
Sar-e-Sang (Badakhshan/Central Asia): ~4000–2000 BCE → pre-literate, active mining zone; supplying lapis lazuli to early literate civilizations; not a civilization per se, but indispensable to early states. [Today: Core region → Badakhshan; Northeastern Afghanistan.]
Ural Mountains: ~4000–2000 BCE → Pre-literate during most of this span; corridor between Europe and Asia. a metal source: copper and early bronze. [Today: Core region → Russia (primary), Northern Kazakhstan.]
Indian Plate (sutured):
Early Harappan / Pre-Harappan cultures
Planned villages, regional interaction networks
Indus script appears (undeciphered)
Agricultural surplus and craft specialization
Trade: ~3000-2001 BCE → There is robust evidence of trade between the Indus, Mesopotamia, and Iran regions. Mesopotamian records from the Ur III period (~2100–2000 BCE) mention a Meluhhan village and Meluhhan individuals residing abroad, but direct long-distance contact with them appears to decline after the collapse of Indus urbanism.
Meluhha/Melukhkha/Melukham: This (likely) was the Mesopotamian name for the Indus Valley Civilization trade world—whose economic system extended northward to access Badakhshan lapis lazuli—without incorporating the region itself into Indus political or urban structures.
Badakhshan lapis lazuli stones: ~4000–2000 BCE → Pamir Mountains informally a circular/ring-like highland (today’s Pamir Knot). “Circle” didn’t imply a single closed range but a ring of mountains enclosing a high plateau: today’s Hindu Kush (southwest), Karakoram (southeast), Tian Shan (north), and Kunlun Mountains (east). On the southwestern arc of this “circle” lay Badakhshan—a resource zone for lapis lazuli—which the Mesopotamians loosely grouped under Meluhha. From an ancient viewpoint, the Pamir region was a circular highland hub that connected early civilizations.
(aka: Mid-Third to Late Second Millennium BCE)
Fully developed urban civilizations
Monumental architecture, standardized weights, laws
Writing widely used for administration and ritual
Horses used in warfare: ~2100–1800 BCE → Sintashta–Petrovka culture (southern Urals); evidence: chariot burials
Chariot warfare spreads to civilizations: ~1800–1600 BCE → Mesopotamia, Egypt, Indus periphery, Shang China.
Dock-like maritime structure: ~2600–1900 BCE (Mature Harappan, Indus Valley—Lothal): Purposely-built, indicating organized maritime trade. Supported loading/unloading of goods: agriculture, animal husbandry, and craft production.
Indian Plate (sutured):
Mature Harappan Civilization
Large planned cities: Harappa, Mohenjo-daro, Dholavira
Advanced urban sanitation and trade
Script in use, but meaning unknown
(aka: Second Millennium BCE)
Collapse or transformation of early states
Climate stress, shifting river systems
Decline of Bronze Age urbanism
Indian Plate (sutured):
Decline of Harappan urban centers: ~1900 BCE.
Ruralization, regional cultures, new tradition: ~1900–1200 BCE → Harappan population disperses into smaller rural settlements—their writing, languages, identities unknown.
Indo-Iranian religious system: ~1800–1500 BCE → A shared Indo-Iranian religious system appears to have existed before 1800 BCE. By 1500 BCE, distinct Vedic and Iranian traditions are visible in the Rigveda and the Avesta. Both traditions retain the same inherited religious terminology but use it differently. Asura in the Vedas corresponds linguistically to Ahura in Iranian texts, while Deva in the Vedas corresponds to Daeva in Iranian texts. In the two traditions, these categories are applied in opposite ways: figures treated as gods in one tradition are treated as hostile or demonic in the other.
Indo & Iranian manuscripts: There seem to be overlaps in Old Iranian and Vedic Sanskrit—enough to club them into one Indo-Aryan bucket. Although the scriptures of both cultures are understood to have been composed earlier, the oldest surviving manuscripts of the Rigveda date to ~11th century CE, and the oldest surviving manuscripts of the Avesta date to ~13th–14th centuries CE.
Indus Valley script: Disappeared by around 1900 BCE, with the decline of the Mature Harappan urban system and the abandonment of major cities. After this point, the use of writing ceases entirely in the archaeological record. The script remains undeciphered, and there is no evidence that it was transmitted to or adopted by later cultures.
(aka: Early-Second to Early-First Millennium BCE)
Iron metallurgy spreads (The Iron Age)
Smaller polities, kingdoms, tribal states
Oral traditions formalized; writing re-emerges regionally
Elephants used for warfare: ~1200–1000 BCE → South Asia (northwest and Gangetic regions)
China: ~1200 BCE → fully literate; Oracle bone script (Shang dynasty); first unambiguous writing system—no evidence before this; [Today: Core region → Yellow River (Huang He) basin, North China Plain; China.]
Indian Plate (sutured):
Iron use expands in Ganga basin
Elephants used in warfare
Janapadas form: ~900 BCE.
Gradual reorganization from 1200–900 BCE.
Then, janapadas emerge; urbanization resumes from 900–600 BCE.
Unsolved mystery: There is a gap of about 1,000–1,300 years from 1900 BCE onwards before writing reappears in South Asia with the Brahmi script in the 3rd century BCE.
(aka: Early-First to Mid-First Millennium BCE)
Continuous, deciphered writing
Coins, inscriptions, chronicles
Named rulers and states persist
Indian Plate (sutured):
The Sixteen Mahajanapadas: ~600–400 BCE
Unsolved mystery continues: No inscriptions survive, so written scripts are archaeologically unknown. Indirect evidence from later Mauryan inscriptions suggests that regional Prakrit (Middle Indo-Aryan) languages were already in use; Sanskrit likely functioned as an oral elite language (Vedic Sanskrit evolved into Classical in elite circles). But no direct linguistic, epigraphic evidence from the period.
Gautama Buddha: ~480–400 BCE (modern scholarly consensus);
Traditional dating (563–483 BCE). Born into the Śākya clan, who formed a gaṇasaṅgha (oligarchic republic).
Śākya clan's territory lay between the Mahājanapadas of Kosala and Magadha, in the Himalayan foothills (modern Nepal–UP border).
Buddha didn’t hail from a Mahājanapadas, but he operated within the Mahājanapada political and cultural milieu.
