In simple words: After the Harappan cities declined, a group of people who spoke an early form of Sanskrit, the Aryans, became dominant in north-west India. They composed the Vedas, India’s oldest religious texts. The period named after these texts (c. 1500–600 BCE) is called the Vedic Age.
Vedic literature was composed mainly between 1500 and 1000 BC (the core Rig Vedic phase). → PYQ: WBCS Prelims 2009
Unlike the Harappans, the Vedic people were mainly rural and pastoral (cattle-keepers). They knew the horse well. Iron appears only in the Later Vedic period.
Remember “Harappa = city + no horse; Rig Veda = village + horse”.
2. Who were the Aryans? Origin Theories
In simple words: “Arya” in Sanskrit means “noble”. Today historians use “Aryan” for people who spoke Indo-Aryan languages. It refers to a language group, not a biological race.
Older books describe the Aryans as a race; today the term is used for a linguistic and cultural group, as Max Müller himself stressed. → PYQ: WBCS Prelims 2009
Most accepted view today: speakers of Indo-European languages came from the Eurasian steppes, arriving in phases of migration, not as one “invasion”, from about 2000–1500 BCE. A 2019 ancient-DNA study (Narasimhan et al.) shows steppe ancestry arriving after about 2000 BCE.
Evidence of Aryan links outside India:
Boghazkoi inscription (Turkey, c. 1400 BCE). It is a treaty between the Hittite and Mitanni kings that names the Vedic gods Indra, Mitra, Varuna and the Nasatyas. → PYQ: WBCS Prelims 2020
The Avesta, the holy book of Iran, uses language very close to the Rig Veda.

Each Veda has four parts: Samhita (hymns), Brahmana (ritual explanations), Aranyaka (“forest texts”) and Upanishad (philosophy). → PYQ: WBCS Mains 2017

The Rig Veda has 1,028 hymns (1,017 plus 11 Valakhilya hymns), in 10 mandalas of unequal size. It is NOT monolithic: it was composed in layers over centuries. → PYQ: WBCS Prelims 2024 | WBCS Mains 2016
Mandalas II–VII are the oldest “family books“. They belong to the families of Gritsamada (II), Vishvamitra (III), Vamadeva (IV), Atri (V), Bharadvaja (VI) and Vasishtha (VII).
Brahmanas: prose manuals that explain sacrifices. The Shatapatha Brahmana is the largest. It tells the story of Videgha Mathava carrying Agni east across the Sadanira (Gandak), which shows Aryan expansion eastward.
Aranyakas: “forest books” for hermits. They form a bridge between ritual and philosophy.
Upanishads (upa-ni-shad, “sitting near” the teacher) are also called Vedanta, “end of the Vedas”. There are 108 in the traditional list, of which about 13 are principal. They were compiled around 800–500 BCE; WBCS’s answer is “around 600 BC”. → PYQ: WBCS Prelims 2016 They teach Brahman, Atman, karma, rebirth and moksha, and react against ritualism.
Upanishad
Famous for
Brihadaranyaka (oldest and largest)
Yajnavalkya debates Gargi and teaches Maitreyi. “Asato ma sadgamaya, tamaso ma jyotirgamaya…” → PYQ: WBCS Prelims 2024
Chandogya
“Tat tvam asi” (Uddalaka Aruni to Shvetaketu); three ashramas; mention of Devakiputra Krishna; the earliest reference to untouchables (Chandala). → PYQ: WBCS Mains 2021
Mundaka
“Satyameva Jayate“, the national motto
Katha
Nachiketa and Yama (dialogue on death)
Mandukya
Shortest; explains Om
Isha, Kena, Shvetashvatara, Jabala
Isha opens the Isha-Kena group; Jabala mentions all four ashramas
3.3 Vedangas (six “limbs of the Veda”)
Use “SKV-NCJ” (Shiksha, Kalpa, Vyakarana, Nirukta, Chhanda, Jyotisha):
They come in pairs: Sankhya–Yoga, Nyaya–Vaisheshika, Mimamsa–Vedanta.
3.5 Smritis, Sutras & Epics
Smritis (Dharmashastras):Manu Smriti (the oldest), then Yajnavalkya, Narada, Brihaspati and Parashara. → PYQ: WBCS Mains GK 2022
Epics (final form after the Vedic period, c. 400 BCE–400 CE):
Mahabharata: by Vyasa. It grew from Jaya to Bharata to Mahabharata, and has about 100,000 verses (the Shatasahasri Samhita) in 18 parvas. The Bhagavad Gita is in the Bhishma Parva.
Ramayana: by Valmiki, the Adi Kavya. It has about 24,000 verses in 7 kandas.
4. Geography: Rivers (Ancient → Modern)
Rivers of the Sapta Sindhu with their ancient (Rig Vedic) and modern names.
In simple words: The Rig Vedic people lived in Sapta Sindhu, the “land of seven rivers” (roughly Punjab and the north-west). Later they moved east into the Ganga–Yamuna plains.
“Vit-Jhel, Asi-Chen, Paru-Ravi, Vipa-Beas, Shutu-Sut”. Go west to east across Punjab: Jhelum, Chenab, Ravi, Beas, Sutlej.
Sarasvati is called “Naditama” (best of rivers) and is the most praised and most celebrated river of the Rig Veda; it is mentioned again and again in the hymns. → PYQs: WBCS Mains 2017, 2021. The Sindhu (Indus) is the river after which the region and India itself are named.
The Ganga is mentioned once and the Yamuna three times in the Rig Veda. The Nadistuti Sukta (X.75) praises the rivers.
Later Vedic: the heartland became the Kuru–Panchala area (the Ganga–Yamuna doab), and the culture spread to Kosala, Kashi and Videha. Anga, Magadha and Vanga were seen as impure and outside the Vedic heartland. → PYQs: WBCS Mains 2016, 2017
5. Rig Vedic vs Later Vedic: Master Comparison
The eastward shift: from the Sapta Sindhu (Rig Vedic) to the Ganga–Yamuna Doab and beyond (Later Vedic).
Aspect
Rig Vedic (1500–1000 BCE)
Later Vedic (1000–600 BCE)
Region
Sapta Sindhu (Punjab, Afghanistan border)
Ganga–Yamuna doab to Videha (north Bihar)
Polity
Tribal. The Rajan was a chief who protected cattle and was elected/approved by the Samiti.
Territorial kingdoms (rashtra, janapada). Kingship became hereditary, with grand titles: Samrat, Ekarat, Virat, Bhoja.
Assemblies
Sabha (council of elders, which women could attend), Samiti (general assembly; elected the chief), Vidatha (oldest; mentioned 122 times; had religious, military and economic roles), Gana
Sabha and Samiti lost power. Women were excluded from the Sabha. The Vidatha disappeared.
The Ratnins (about 12, listed in the Rajasuya), including Bhagadudha (tax collector), Samgrihitri (treasurer), Suta (charioteer/bard), Akshavapa (accounts), Palagala (messenger) and Kshattri (chamberlain)
Tax
Bali, a voluntary gift
Bali became compulsory, collected by the Bhagadudha
Society
Fairly egalitarian; varna based on occupation and not rigid. The four varnas appear first in the Purusha Sukta (Mandala X).
Varna became hereditary and rigid. Gotra appeared. The status of Shudras declined.
Women
Better status: they could attend assemblies, study and compose hymns (Ghosha, Apala, Lopamudra, Vishvavara). No child marriage. Widow remarriage and niyoga existed.
Status declined: no assemblies. A few women scholars remained (Gargi, Maitreyi).
Economy
Pastoral: the cow = wealth (gavishti, “search for cows”, meant war; the king was gopati). Some farming (yava = barley). Barter. Nishka (a gold ornament) was used as a unit. Metal: ayas (copper/bronze).
Settled agriculture dominates: rice (vrihi) and wheat, with large ploughs pulled by many oxen. Iron (shyama/krishna ayas) appears. Crafts and guilds begin. Trade grows.
Pottery
Ochre/OCP links
Painted Grey Ware (PGW)
Religion
Nature gods: Indra (most important), Agni, Varuna, Soma. Simple prayers for cattle, sons and victory. No temples or idols.
Prajapati (the creator) becomes supreme, with Vishnu and Rudra rising. Elaborate sacrifices and priestly dominance. The Upanishads react against ritual.
Sabha and Samiti were the two assemblies of the early Vedic period and are called democratic institutions of the Rigvedic Aryans. The Atharva Veda calls them the “two daughters of Prajapati“. → PYQs: WBCS Prelims 2000, 2020
The assembly that elected the tribal chief was the Samiti. → PYQ: WBCS Mains 2015
Earliest reference to the four varnas: the Purusha Sukta (Rig Veda X.90). Brahmins came from Purusha’s mouth, Kshatriyas from the arms, Vaishyas from the thighs and Shudras from the feet. → PYQ: WBCS Mains 2016 | WBCS Prelims 2012
Gotra (literally “cow-pen”) came to mean a lineage from a common ancestor in the Later Vedic period. Marriage within the same gotra was forbidden (gotra exogamy).
Ashramas (stages of life):Brahmacharya (student), Grihastha (householder) and Vanaprastha (forest-dweller) appear in the Chandogya. Sannyasa (renunciation) is added later; the Jabala Upanishad first names all four.
6. Religion & Gods
God
Role / fact
Indra
Most important god (about 250 hymns). God of rain and thunder (vajra). Called Purandara, “destroyer of forts”. Killed the demon Vritra. → PYQs: WBCS Mains 2017, 2020, 2023
Agni
Second most important (about 200 hymns). Messenger between gods and humans.
Varuna
God of water and the sky. Upholder of Rita (cosmic order). → PYQ: WBCS Mains 2015
