03 Ancient South Asia

Harappan cities and trade

The Harappan civilization, also called the Indus Valley civilization, flourished in parts of present-day Pakistan and northwestern India. Its mature urban phase lasted roughly from 2600 to 1900 BCE.

Harappa and Mohenjo-daro had carefully planned streets, standardized baked-brick construction, wells, and drainage systems. These features suggest coordinated civic planning, but the precise form of political authority remains unknown.

Harappan craftspeople made pottery, metal objects, beads, and carved seals. Seals and other evidence indicate trade with regions to the west, including Mesopotamia. The civilization used a distinctive script that remains undeciphered, so written records do not allow historians to confidently reconstruct its rulers, beliefs, or institutions.

The cities declined gradually after about 1900 BCE amid changing settlement patterns and regional conditions. No single cause explains this transformation.

Vedic traditions and changing society

From about the second millennium BCE, Indo-Aryan languages and cultural practices spread and developed in South Asia, interacting with communities already living there. The Vedic period is known chiefly through the Vedas, collections of Sanskrit hymns and ritual texts transmitted orally. The Rigveda, the oldest collection, praises deities and preserves prayers and ritual poetry. Later texts, including the Brahmanas and Upanishads, explain ritual practices and explore philosophical questions.

Early Vedic society included pastoral life, cattle wealth, and ritual offerings. Over time, communities spread eastward into the Indo-Gangetic plain. Agriculture, ironworking, and more settled political organization grew in importance.

Texts describe a social ideal organized into four varnas: Brahmins (priests), Kshatriyas (rulers and warriors), Vaishyas (cultivators and traders), and Shudras (service groups). This model should not be treated as a complete description of how every community lived; social practices varied across place and time.

Vedic ritual centered on offerings performed by trained priests. Later Vedic and Upanishadic thought also emphasized karma, or action and its consequences; samsara, or rebirth; and liberation from the cycle of rebirth. These ideas became important in several South Asian religious traditions. What is now called Hinduism developed over a long period from Vedic and other traditions; it was not a single, fully formed religion in the earliest Vedic age.

States and political change

During the first millennium BCE, farming expansion, iron tools, towns, and trade helped transform northern South Asia. By roughly the eighth to sixth centuries BCE, texts refer to the mahajanapadas, or “great states,” a group of large territorial polities. Some were monarchies; others had governing assemblies or oligarchic institutions.

Competition among these states strengthened some rulers and centers. Magadha, in the lower Ganges region, became especially powerful and later formed the core of the Mauryan Empire.

Buddhism and Jainism

Political and urban change coincided with the growth of religious communities that questioned or reinterpreted Vedic ritual authority. Buddhism teaches that suffering is connected to craving and that ethical conduct, disciplined attention, and insight can lead toward liberation.

Jainism emphasizes liberation through disciplined conduct and ahimsa, or nonviolence toward living beings. Both Buddhism and Jainism developed monastic communities while also addressing lay followers.

Their teachers and early communities emerged in the same broad era as expanding states and towns. These traditions developed alongside Brahmanical traditions rather than simply replacing them.
