Before the Vedic Age (roughly before 1500 BCE), South India was characterized by a distinct, indigenous cultural sequence spanning from the Mesolithic (c. 6000–3000 BCE) to the Neolithic period (2500–1000 BCE). This period was defined by farming communities, microlith production, and later the Megalithic culture, which was independent of the northern Bronze Age, directly entering the Iron Age.
The earliest Iron Age sites in southern India date from c. 1200 to 200 BCE, and some of the sites are contemporary with the Sangam period.
Hallur in Karnataka and Adichanallur in Tamil Nadu are notable Iron Age sites of ancient southern India
Key Aspects of Pre-Vedic South India:
Cultural Stages: The region remained in the Mesolithic stage until around 2500 BCE, transitioning into a Neolithic, and later, an Iron Age characterized by Megalithic, or "big stone," burials.
Lifestyle: Early inhabitants were largely hunter-gatherer tribes and early agriculturalists, with farming communities developing in areas like modern Tamil Nadu, Andhra Pradesh, and Karnataka.
Technological Shift: South India did not experience a traditional Bronze Age, moving directly from the Chalcolithic or Neolithic phase to the Iron Age.
Regional Independence: Before 1500 BCE, the region had a distinct culture often separate from the Indus Valley Civilization. Early Megalithic sites indicate an independent, specialized culture.
Migration Evidence: Excavations in sites like Adichanallur suggest that Megalithic cultural practices spread from the south, with evidence suggesting a migration or movement between northern and southern India.
Following this period, the Iron Age Megalithic culture became dominant, leading up to the historic period of the Chera, Chola, and Pandya kingdoms.
