Prehistoric & Ancient India (Until c. 650 CE)
c. 2,500,000 - 10,000 BCE
Paleolithic (Old Stone Age) Period
This era marks the earliest human presence in India, characterized by nomadic hunter-gatherer societies. Early humans used crude stone tools made of quartzite, such as hand axes and choppers. Key sites like Bhimbetka (Madhya Pradesh) and Attirampakkam (Tamil Nadu) provide invaluable evidence, including some of the world's oldest stone tools and rock paintings that offer a glimpse into their life.
c. 10,000 - 4,000 BCE
Mesolithic & Neolithic Ages
The Mesolithic Age saw the development of smaller, more refined stone tools called microliths and the beginning of animal domestication. The subsequent Neolithic Age heralded the 'Neolithic Revolution', marked by the beginning of agriculture, settled villages, pottery, and the polishing of tools. The site of Mehrgarh in Balochistan shows the earliest evidence of farming and herding in South Asia.
c. 2600 – 1900 BCE
Indus Valley Civilization (Harappan Civilization)
One of the world's first great urban civilizations, the IVC flourished in the Indus River basin. It was a highly advanced Bronze Age society known for its meticulous urban planning, with cities like Harappa and Mohenjo-daro featuring sophisticated drainage systems and a grid-like street layout. Key features include the Great Bath at Mohenjo-daro, dockyards at Lothal, and unique terracotta seals like the Pashupati Seal. Their script remains undeciphered, and theories for their decline include climate change and Aryan invasion. Learn more about the great Dynasties of India.

The Vedic Period
This era is defined by the composition of the Vedas. Early Vedic Period (c. 1500-1000 BCE): Described in the Rigveda, society was semi-nomadic and pastoral, with the tribe (jana) as the main political unit, led by a Rajan. Later Vedic Period (c. 1000-600 BCE): Society became agrarian with the use of iron. Large kingdoms (Janapadas) emerged, and the social structure became rigid with the Varna system. The concept of divine kingship grew stronger.
c. 600 – 322 BCE
Age of Mahajanapadas & Religious Awakening
An era of intense political and philosophical development. Sixteen powerful kingdoms, or Mahajanapadas, emerged, including Magadha, Kosala, and Avanti. This period also witnessed the rise of new philosophical schools (Shramana traditions) challenging Vedic orthodoxy, most notably Buddhism, founded by Gautama Buddha, and Jainism, propagated by Mahavira.
322 – 185 BCE
The Mauryan Empire
Founded by Chandragupta Maurya and his mentor Chanakya, this was the first great pan-Indian empire. Its centralized administration, detailed in Kautilya's Arthashastra, was a marvel of efficiency. Under Ashoka the Great, the empire reached its zenith. After the bloody Kalinga War, Ashoka's conversion to Buddhism and his policy of Dhamma marked a unique experiment in governance based on peace, propagated through his famous rock and pillar edicts.
c. 200 BCE - 300 CE
Post-Mauryan Period: A Time of Flux

In the Deccan, the Satavahanas established a powerful empire.
c. 320 – 550 CE
The Gupta Empire: The Golden Age of India
The Gupta period is renowned for its extraordinary achievements in science, mathematics, literature, and art. Key contributions include the decimal system and the concept of zero, astronomical discoveries by Aryabhata, and the literary masterpieces of Kalidasa.

The Tripartite Struggle
A century-long conflict for control over the imperial city of Kannauj between three major powers: the Gurjara-Pratiharas of the west, the Palas of the east, and the Rashtrakutas of the Deccan.
