Chronological Breakdown

To arrange these periods, we look at the technological and social evolution of ancient India:

1. (A) Chalcolithic (c. 4000 – 1500 BCE): This is the "Copper-Stone" age. It marks the first use of metal (copper) alongside stone tools. While some Chalcolithic cultures were contemporary with the Harappans, the transition to metal-using sedentary farming communities began here.
2. (C) Harappan Civilisation (c. 2600 – 1900 BCE): Also known as the Indus Valley Civilisation, this was the first major urbanisation in India. Although it is technically a Bronze Age culture, in the context of this sequence, it represents the organized urban phase following the initial Chalcolithic developments.
3. (B) Early Iron, Megalithic Burials (c. 1200 – 600 BCE): Following the decline of the Harappan cities, the use of Iron became widespread. In South India, this period is characterized by "Megaliths" (large stone burial structures).
4. (D) Early Historic (c. 600 BCE – 4th Century CE): This period begins with the "Second Urbanisation," the rise of the Mahajanapadas (16 great kingdoms), the life of the Buddha, and eventually the Mauryan Empire.
