India’s ancient history begins with one of the world’s earliest urban cultures – the Indus Valley Civilization (IVC) – and later the Vedic Period, which laid the social, political, and cultural foundation of Indian society.

Both these periods are extremely important for UPSC, SSC, State PSC, and other competitive exams.

Indus Valley Civilization (3300 BCE – 1300 BCE)

Also called the Harappan Civilization, it flourished along the Indus and Ghaggar-Hakra rivers (present-day Pakistan & northwest India).

Key Features

• Urban Planning – well-planned cities like Harappa, Mohenjo-Daro, Dholavira, Lothal with grid pattern and drainage system.
• Architecture – Great Bath (Mohenjo-Daro), Granaries, Citadels, Dockyard (Lothal).
• Economy – agriculture (wheat, barley, cotton), trade with Mesopotamia, weights & measures, seals.
• Crafts – pottery, bead-making, metallurgy (bronze, copper).
• Religion – worship of Mother Goddess, Proto-Shiva (Pashupati seal), animals, sacred trees.
• Decline Theories – climate change, decline in trade, Aryan invasion, river shift (Indus/Saraswati).

Vedic Period (1500 BCE – 600 BCE)

The Vedic Age began with the arrival of the Indo-Aryans, who composed the Vedas, the earliest religious texts of India. It is divided into two phases:

1. Early Vedic (Rig Vedic) Period (1500 BCE – 1000 BCE)

• Texts – Rigveda (oldest Veda).
• Society – tribal, patriarchal, kinship-based.
• Economy – pastoral (cattle as wealth), later agriculture (barley, wheat).
• Polity – monarchy; assemblies like Sabha and Samiti were important.
• Religion – nature worship (Indra, Agni, Varuna, Surya). No idol worship.

2. Later Vedic Period (1000 BCE – 600 BCE)

• Texts – Samaveda, Yajurveda, Atharvaveda, Brahmanas, Aranyakas, Upanishads.
• Society – Varna system became rigid; women’s status declined.
• Economy – agriculture flourished (rice mentioned), use of iron (Krishna Ayas).
• Polity – kings became powerful; rise of larger kingdoms (Mahajanapadas).
• Religion – rituals, sacrifices (yajnas), priestly dominance; philosophical ideas (Upanishads) emerged.
