Timeline — Sanātana Dharma Through the Ages

c. 3300–1300 BCE Indus Valley Period

c. 3300–1900 BCE

Indus Valley Civilisation — Mature Phase

Major urban centres at Mohenjo-daro and Harappā. Sophisticated drainage, standardised weights. Evidence of proto-religious practices: seated figures possibly in yoga posture, fire altars. Script undeciphered. Direct relationship to later Sanātana Dharma is debated.

Flood, An Introduction to Hinduism (1996), pp. 21–28

c. 1900–1300 BCE

Decline and Late Indus / Transition Period

Gradual decline of Indus urban centres. Multiple causes proposed (climate change, river course shifts, internal change). Overlap with or transition into early Vedic culture — the nature and extent of this transition is one of the most debated questions in South Asian archaeology and history.

Michael Witzel, "Vedas and Upaniṣads" in The Blackwell Companion to Hinduism (2003)

c. 1500–900 BCE Early Vedic Period

c. 1500–1200 BCE

Ṛg Veda — composition of the earliest layers

The oldest surviving Indo-European literature. 1,028 hymns to the Vedic devas — Agni (fire), Indra (storm), Varuṇa (cosmic order), Sūrya (sun). Key concepts: Ṛta (cosmic order), Satya (truth), the Aśvins, the Maruts. Oral composition; transmitted with extraordinary precision for over 3,000 years.

Jamison and Brereton, The Rigveda (OUP, 2014), Introduction

c. 1200–900 BCE

Sāmaveda, Yajurveda, Atharvaveda — composition

The three later Vedas. Sāmaveda: the Ṛg Veda's hymns arranged for liturgical singing. Yajurveda: prose sacrificial formulas for the adhvaryu priest. Atharvaveda: spells, charms, and early philosophical speculation; earliest prominent use of Dharma as an ethical term.

Witzel (2003); Hiltebeitel, Dharma (OUP, 2011), Chapter 1

c. 900–500 BCE Brāhmaṇa and Early Upaniṣad Period

c. 900–700 BCE

Brāhmaṇa texts — composition

Elaborate prose explanations of Vedic ritual. Śatapatha Brāhmaṇa is the most comprehensive. Identify cosmic correspondences between sacrificial actions and cosmic events. Begin philosophical speculation about the ātman (self) and its relationship to ultimate reality.

Jan Gonda, Vedic Literature (1975)

c. 800–500 BCE

Early Upaniṣads — Bṛhadāraṇyaka and Chāndogya

The two oldest and longest Upaniṣads. Bṛhadāraṇyaka: Yājñavalkya's dialogues on Ātman, Brahman, the self that transcends death. Chāndogya: the Tat Tvam Asi teaching (6.8.7) and the five-fire doctrine of rebirth (5.3–5.10). Systematic philosophical speculation about ultimate reality begins.

Olivelle, The Early Upaniṣads (OUP, 1998), Introduction

c. 600–200 BCE Classical Period — Darśanas and Epics

c. 600–400 BCE

Middle Upaniṣads — Kaṭha, Muṇḍaka, Māṇḍūkya, Śvetāśvatara

Further development of Brahman-Ātman identity, karma and rebirth doctrine, and the first theistic Upaniṣad (Śvetāśvatara) explicitly identifying the supreme with a personal God (Rudra/Śiva). Muṇḍaka: distinction between lower and higher knowledge. Māṇḍūkya: the three states of consciousness and the fourth (Turīya).

Olivelle (1998); Flood (1996), Chapter 4

c. 500–200 BCE

Mahābhārata — core composition

The world's longest epic — 100,000+ ślokas. Contains the Bhagavad Gīta (Chapters 25–42 of the Bhīṣmaparva) — the tradition's most widely read philosophical text. Also contains the Śāntiparva and Anuśāsanaparva — extensive discussions of Dharma, ethics, political philosophy. BORI Critical Edition is the standard scholarly text.

Hiltebeitel, Dharma (2011); BORI Critical Edition (1933–1966)

c. 400–200 BCE

Six Darśanas take shape — Sāṃkhya, Yoga, Nyāya, Vaiśeṣika, Mīmāṃsā, Vedānta

The six āstika (Veda-accepting) philosophical schools systematise their core positions. Patañjali's Yoga Sūtras (c. 4th–2nd century BCE or earlier) codify the eight-limbed Yoga path. Bādarāyaṇa's Brahmasūtras summarise Upaniṣadic teaching in 555 aphorisms — the foundational Vedānta text on which all later commentaries are written.

Flood (1996), Chapter 8; Bryant, Yoga Sūtras (2009), Introduction

c. 300 BCE

Kauṭilya's Arthaśāstra

The most systematic ancient Indian treatise on statecraft, political economy, and the pursuit of Artha. Attributed to Kauṭilya (Cāṇakya), minister to Candragupta Maurya. Treats the relationship of Dharma, Artha, and Kāma with unsentimental political realism. Olivelle's 2013 OUP translation is the standard critical edition.

Olivelle, King, Governance, and Law (OUP, 2013)

c. 200 BCE – 500 CE Dharmaśāstra, Purāṇas, Rāmāyaṇa

c. 200 BCE – 200 CE

Manusmṛti (Mānava Dharmaśāstra)

The most influential Dharmaśāstra text — law, ethics, social organisation, and the duties of the four Varṇas across the four Āśramas. Elaborates Dharma as the first Puruṣārtha in systematic legal form. Olivelle's 2005 OUP critical edition with commentary is the standard scholarly text.

Olivelle, Manu's Code of Law (OUP, 2005)

c. 300 BCE – 300 CE

Rāmāyaṇa — Vālmīki's version reaches its current form

The story of Rāma, Sītā, and the conquest of Laṅkā — the tradition's primary exploration of ideal kingship (Rāmarājya), ideal womanhood, and ideal brotherly duty. Shorter than the Mahābhārata (~24,000 ślokas) but pervasively influential across South and Southeast Asian culture.

Flood (1996), Chapter 5

c. 500–1200 CE Age of Commentaries and Bhakti Beginnings

c. 788–820 CE

Śaṅkara — Advaita Vedānta systematised

Śaṅkara writes his commentaries on the Brahmasūtras, the principal Upaniṣads, and the Bhagavad Gīta — establishing Advaita Vedānta as the most philosophically rigorous of the Vedānta schools. Establishes four monastic centres (Maṭhas) across India. His works become the primary interlocutor for all subsequent Vedānta.

Deutsch, Advaita Vedānta (1969); Gambhirananda trans. (BSB, 1996)

c. 1017–1137 CE

Rāmānuja — Viśiṣṭādvaita Vedānta

Rāmānuja writes the Śrī-Bhāṣya — the most sustained philosophical critique of Advaita and the systematic establishment of Viśiṣṭādvaita. Identifies Brahman with Viṣṇu-Nārāyaṇa. The world and souls are Viṣṇu's real body. Liberation is eternal loving proximity to Viṣṇu, not absorption into an impersonal absolute.

Carman, The Theology of Rāmānuja (Yale, 1974); Thibaut trans. (SBE Vol. 48, 1904)

c. 1238–1317 CE

Madhva — Dvaita Vedānta

Madhva establishes Dvaita — the most strictly theistic of the three Vedānta schools. The absolute distinction between God (Viṣṇu), souls, and world is eternal and real. Viṣṇu alone is absolutely independent (Svatantra). All other reality is absolutely dependent (Paratantra). The highest liberation is eternal blessed service to Viṣṇu.

Nicholson, Unifying Hinduism (Columbia, 2010), Chapter 3

c. 600–1700 CE Bhakti Movement

c. 600–900 CE

Tamil Bhakti — Āḷvārs and Nāyaṉmārs

The Vaiṣṇava Āḷvārs (12 saints, including Tiruppāṇ Āḷvār and Āṇṭāḷ) and the Śaiva Nāyaṉmārs (63 saints, including Appar, Campantar, Cuntarar) compose intense devotional poetry in Tamil. This marks the earliest and most powerful phase of what becomes the pan-Indian Bhakti movement — devotion as the primary path to God, transcending Varṇa distinctions.

Flood (1996), Chapter 6

c. 1200–1700 CE

North Indian Bhakti — Kabīr, Mīrābāī, Tukārām, Sūrdās, Tulasīdās

The Bhakti movement reaches northern India. Kabīr (c. 1440–1518): weaver-poet composing in vernacular Hindi, transcending Vaiṣṇava and Islamic boundaries. Mīrābāī (c. 1498–1547): Rajput princess composing intense Kṛṣṇa-bhakti poetry. Tulasīdās (c. 1532–1623): Rāmcaritmānas — the Hindi Rāmāyaṇa, among the most widely read texts in North India. Tukārām (c. 1598–1650): Marathi devotional poet.

Flood (1996), Chapter 6; Nicholson (2010)

1800s – present Modern Period

1828

Ram Mohan Roy founds the Brahmo Samāj

First major reformist movement responding to colonial encounter. Emphasises monotheism, rejects murti worship and caste discrimination, draws on Upaniṣadic non-dualism. Marks the beginning of the modern reform tradition.

Flood (1996), Chapter 11

1863–1902

Swami Vivekananda — global Vedānta

Disciple of Ramakrishna. Address to the Parliament of World's Religions, Chicago (1893), marks the beginning of Vedānta's global reach. Founds the Ramakrishna Mission (1897). His practical Vedānta — combining Advaita with social action — becomes one of the most influential modern readings of Sanātana Dharma.

Nicholson (2010); Flood (1996), Chapter 11

1869–1948

Mohandas Gandhi — Ahiṃsā and political independence

Grounds his political programme of non-violent resistance (Satyāgraha) explicitly in Ahiṃsā and the Bhagavad Gīta. Indian independence movement (1947) demonstrates Ahiṃsā as a practical political force on a civilisational scale.

Flood (1996), Chapter 11; Chapple, Nonviolence (1993)

On ancient dating: Dates for Vedic and early classical texts are scholarly estimates based on linguistic analysis, archaeological correlation, and internal evidence. They are not traditional dates. The tradition itself uses different chronological frameworks. For example, the Mahābhārata war is traditionally dated to 3102 BCE (start of the Kali Yuga); scholarly estimates for the core composition range from c. 500–200 BCE. Both frameworks are documented here; neither is endorsed over the other.
