From pastoral tribes on the Sapta Sindhu to settled kingdoms of the Ganga-Yamuna Doab — Aryan origins, the Rig Vedic pantheon and polity, the rise of varna, and the full body of Vedic literature.
It is difficult to say the Aryans belonged to a single race. Max Müller held that they first lived near the steppes of Central Asia (hence "European"), based on shared linguistic roots — they spoke an Indo-European language. Other theories differ sharply: Tilak argued for an Arctic homeland; Dayanand Saraswati argued for Tibet. The Aryans entered the Sapta Sindhu region through the Khyber and Bolan passes. Indo-European links appear in inscriptions well before the Rig Veda itself — the Mitanni inscriptions (c. 1400 BC, Syria) invoke Vedic gods and mention the Indus and its five branches, suggesting an Iranian route of entry; the term "Arya" also appears in horse-sacrifice records from Tajikistan and the Swat Valley. Society was early on pastoral, agricultural and male-dominated; there was no domination by Brahmins at this stage.
Two recorded conflicts mark this period. Aryans vs pre-Aryans: the Rig Veda describes clashes with the indigenous Dasas and Dasyus — the latter phallus-worshippers who did not use cattle for dairy. Aryan soldiers used Varman (coats of mail); the chief Trasadasyu overpowered the Dasyus in what is termed Dasyuhatya. The Battle of the Ten Kings (Dasarajna) was an intra-tribal war rooted in a rivalry between the sages Vishwamitra and Vasishtha over who would serve as the Bharatas' guru. Vishwamitra led ten kings (five Aryan, five non-Aryan) against the Bharatas under King Sudas at the river Parushni (the Ravi) — the Bharatas won, later allying with the Purus to form the Kurus, the dynasty that dominates the Later Vedic age.
The Rig Veda, dated 1500-1200 BC, is the earliest Indo-European text, organised into 10 Mandalas (2-7 the oldest; 1, 8, 9, 10 the latest), addressed mainly to Indra, Agni and Varuna. It shares similarities with the Iranian Zend Avesta. The Indus (Sindhu) and its 5 branches are named — Vitasta (Jhelum), Askini (Chenab), Purushni (Ravi), Vipas (Beas), Sutudri (Sutlej) — while the Saraswati is praised as "Naditama" (best of rivers). Geographically the hymns reach east to the Ganga-Yamuna, south to the Vindhyas, and west to the Himalayas.
The Rig Vedic Aryans were pastoral — wars were fought over cows and wealth (Gavishthi = search for cows) — with a wooden ploughshare mentioned only in the text's earliest portions. Ayas meant copper/bronze; the sea (samudra) appears just once, suggesting little seafaring knowledge, and there is no clear evidence of organised trade. Politically, the Rajan (chief) was not yet fully hereditary and had no standing army. The Sabha (council of elders) and Samiti (open assembly, binding on the king) were the key institutions — notably, women were allowed to attend the Samiti, making this the last period of relative freedom for women, who could also study the Vedas, undergo Upanayana, and choose a husband via Swayamvara. The Jana was the basic tribal unit; the varna system began purely as an occupational distinction (Arya vs Dasa varna) — a fourth class, the Shudras, appears only at the very end of the age, in the 10th Mandala's Purushasukta.
Religion reflected Henotheism (one God, many forms) rather than monotheism. Indra (≈250 hymns) was the chief deity, followed by Agni (≈200 hymns) and Varuna, guardian of Rita (cosmic law). Soma, linked to an intoxicating drink, has the entire 9th Mandala dedicated to him. Female deities included Aditi, Ushas and Savitri (to whom the Gayatri Mantra is addressed). The only non-Aryan god accepted by the Aryans was Rudra, later identified with Pashupati/Shiva. Notable women scholars (Brahmavadinis) of this milieu — Gargi, Maitreyi and Lopamudra — are associated with the court of King Janaka.
Barring the Rig Veda itself, all other Vedic literature was composed in this period, as the centre of activity shifted from the Sapta Sindhu to the Ganga-Yamuna Doab. New tribes emerged as older ones merged — the Kurus (Bharatas + Purus), Panchalas, Kasis and Magadha. The Mahabharata war, between Kaurava and Pandava branches of the Kuru clan, is dated to roughly 950 BC; both sides held their capital at Hastinapur.
Politically, the Vidhata assembly disappeared, and while the Sabha and Samiti survived, nobles and women were no longer permitted to participate — a sharp reversal from the Rig Vedic age. The Rajan grew more powerful and hereditary, validated through an escalating sequence of royal sacrifices: Rajasuya → Ashwamedha → Vajapeya → Naramedha. Rashtra (territory) appears for the first time, and the political unit shifted from tribal Jana to settled Janapada.
The varna system now expanded to four fixed varnas, and — critically — varna became hereditary: inter-varna marriage and dining were no longer permitted. The Varna-Ashrama-Dharma system (Brahmacharya, Grihastha, Vanaprastha, Sanyasa) took shape, compulsory in full only for Brahmins. Untouchability appears for the first time in this period, alongside Anuloma and Pratiloma marriage (the latter's offspring termed Chandalas) and the concept of Gotra (leading to gotra exogamy). The first three varnas gradually withdrew from production — Brahmins to ritual, Kshatriyas to territorial expansion, Vaishyas to trade — leaving the burden of production to Shudras, which paradoxically spurred trade, guilds (headed by a Jyestaka or Shreshti) and a "second urbanisation" after the Indus Valley Civilisation. Iron technology ("Krishna Ayas") arrived in this period, and rice and wheat became the chief crops alongside barley.
Vedic literature divides into Sruti (revealed, "Apaurusheya" — not of human origin; the four Vedas) and Smriti (commentaries on them). The four Vedas, together called Trayi Vidya (Rig, Yajur, Sama):
| Veda | Theme | Recited by |
|---|---|---|
| Rig Veda | Oldest; prayers & hymns; Gayatri Mantra (3rd Mandala) | Hotri |
| Sama Veda | First text on music; melody & Chandas | Udgatri |
| Yajur Veda | Sacrificial rituals, in prose; Shukla & Krishna branches | Adhvaryu |
| Atharva Veda | Long not considered a "proper" Veda; evil spirits, ~99 diseases | — |
Each Veda is followed by Brahmanas (ritual explanation, in prose — 108 in all; the Shatapatha Brahmana is largest), Aranyakas (forest texts) and Upanishads (108 in number, the "Vedanta" or last portion — the highest source of Indian philosophy, structured as student-teacher dialogues). The 6 Vedangas (Nirukta, Shiksha, Chandas, Vyakarana, Kalpa, Jyotisha) aid correct understanding of the Vedas, while the 4 Upavedas cover medicine (Ayurveda), music (Gandharvaveda), sculpture (Shilpa) and archery (Dhanurveda).
Indra and Varuna's importance declined; new conceptions emerged — Brahma-Prajapati (Kshatriyas), Vishnu (Vaishyas), Maheshwara/Rudra (the Destroyer), and Kubera (wealth). By the end of this age, Brahmin domination was firmly established — rigid caste division, untouchability, and elaborate, costly sacrifices (2,40,000 cows reportedly gifted at one Rajasuya). This unrest is precisely what triggered the 6th-century BC reformist movement that produced Buddhism, Jainism and the Six Schools of Philosophy (Shaddarshanas) — Sankhya, Yoga, Nyaya, Vaisheshika, Vedanta and Purva Mimamsa.
