The history of Hinduism — and the cultural history of India at large — is the history of assimilation.
The culture of the ancient Vedic elites occupies the dominant role in our understanding of Indian history due to their superiority in transmitting knowledge and their cosmopolitanism; however, throughout time there have been distinct cultures on this land, whose histories are shrouded in relative mystery, but which were eventually syncretized into the great alloy that is the Indian ethos of today.
This is a topic that gets a lot of unwanted attention from half-witted “sub-nationalist/separatist” (i.e. Periyarist, Ambedkarite, Khalistani, caste kangers) movements: these people’s historical knowledge is limited to idiotic interpretations of a few popular myths (”Vāmana-Bali/Mahiśāsura is about Aryans and Dravidians”, “Mohini/Ardhanārīśvara is about LGBT”). These crackpot delusions are anachronistic projections of simplistic racial narratives on the past, yet often obtain approval from mainstream writers due to the unholy leftist-subnat alliance. However, they are easily washed away with a rational and dispassionate analysis of the topic, which is what we will do here.
The history of Indian theology is however a rather vast topic, and this article only provides a broad overview. For those who want to read precise details, the undisputed living expert on this topic is mānasa-taraṃgiṇī (blog, theology).
Contents:
Early Vedic literature mentions a number of outgroups — noobs often incorrectly map this onto “Aryan” and “Dravidian” (categorizations which do not reflect how people in the Vedic era saw themselves), so it is important to more reasonably identify who these groups were.
List
Speculative claims about Paṇis:
The revival of many IVC traditions in the Second Urbanization (800 BC onward) is well-known, e.g.
Based on the especial prominence of activities related to trade and finance in these, and the fact that modern baniya (mercantile) castes have the greatest proportion of IVC ancestry, I am inclined to suggest that the Paṇi were the descendants of the IVC mercantile elite who preserved various IVC traditions and crafts into the Vedic period. Note also the similarity between the terms paṇi and paṇa and the derivation paṇi → vaṇij → baniya.
The comprehensive resource on this topic is [5] SC Malik (1968), Indian Civilization: the formative period, who postulates a similar theory. However, note that the book does make some mistakes, such as claiming the word pura has no Indo-European cognate (the Greek cognate is polis).
Speculative comments about Nāgas:
You will often see claims variously associating the Nāgas with tribes in Northeast India, Southeast Asia or Central-East India. Certainly, the term was later used to describe these tribes, but is quite absurd to claim that they all belonged to some widespread “Nāga culture”.
Instead, it seems to me that the Nāgas were a symbol of Hindu assimilation: a label assigned to any people who were initially foreign and hostile to the Āryas but eventually yielding to our ways. Of course, the motif would have been based on a real serpent-worshipping culture in the time of the Kuru kingdom (1000—900 BC), who were initially hostile to the Kurus but eventually made peace with them and assimilated culturally, as attested in the Mahābhārata in the story of Janamejaya and Takṣaka.
(Note that I am willing to accept the Mahābhārata for information on the Vedic period despite its varied period of composition ~1000 BC—400, because e.g. the sarpasatra is independently attested by Vedic literature without appearing to have been copied.)
Note on demons:
Sub-nat circles suffer from the Euhemeristic tendency of believing every mythic or legendary race of “demons” must be based on some race of people (invariably their own), e.g. Asura, Daitya, Dānava, Rākṣasa, Yakṣa. None of these are of Euhemeristic origin: Asura was a generic honorific for a powerful being like “Lord” and grew a negative connotation due to the popularity of David-vs-Goliath-style storytelling; this was not due to some conflict against the Zoroastrians, who simply retained the positive meaning of Asura (however, the Zoroastrian rejection of the Devas as demons was due to their dissent from the prevailing Vedic or para-Vedic culture in their early homeland in Afghanistan). The term Rākṣasa first appears in the epics, and based on its etymology (”protector”) could have either have been motivated by wild tribes protecting forests from the light of civilization or by guards of castles and treasures in heroic mythology. Alternatively they could be based on the Rakṣas people of Baluchistan mentioned by Pāṇini 5.3.117 (see VS Agarwala). Dānava frequently occurs in the r̥g Veda; both only appear in the Purāṇas; Daitya appears in classical texts such as the Manusmr̥iti only as celestial beings without any further negative connotation, both are purely mythical beings from their very conception. Yakṣa is a minor nature spirit in the r̥g Veda itself, a similar class of beings as the Gandharva, etc.
All the aforementioned groups mentioned lived in the same geographic region as the Vedic people, i.e. Udīchya+Brahmāvarta+Madhyadeśa (Punjab+Haryana+UP) — except the Vrātyas who in the latter Vedic period settled the Magadha region (see source [3]), and perhaps the Mlecchas who I might have been of Sindh or the Baloch highlands. What, then, were the religions and cultures in the rest of the Loka, pre-Maurya?
Language distribution: One piece of information is the current distribution of languages, which suggests a peninsular distribution of the Dravidian languages, Eastern distribution of Munda (Austro-asiatic), and the language isolates of Nihali, Burushaki, Kusunda and the remnants in Vedda, which may at one point have had a wider distribution.

Substrate identification: However, it is quite difficult to imagine that e.g. Dravidian could have had such a wide geographical distribution in neolithic/chalcolithic times, and this also doesn’t answer any question about the “pre-Aryan” languages in the North, or the language of the IVC. Certainly if we are willing to entertain that Nihali could have once had a wider distribution, then so could any language completely lost to us today. To have any shot at answering these questions, one must study substrates in extant languages: words in the language not attested in any cognate language, and which share some structure. Hypothesized substrates in Vedic Sanskrit:
Also worthy of note is the “Inner-Outer hypothesis” of e.g. Zoller [6x.5] (see also the comments by mānasataraṃgiṇī therein) which postulates two waves of Aryan migrations into India, one with more archaic Indo-Iranic features, preserved in the North-West, and another a standard Indo-Aryan one.
See also [6x.6] mānasataraṁginī’s comments on all this.
Mālaya tribe: The talk of a “para-Munda” language in Punjab may strike one as odd given its generally presumed Eastern provenance (indeed, Munda resurfaces in the names of Eastern provinces). However, a major Austro-asiatic presence has been noted by several authors including:
[7.1] PC Bagchi (1929), “Pre-Aryan And Pre-Dravidian in India”
[7.2] RC Majumdar (1937), Ancient Indian colonies in the Far East: Vol II (Suvarnadvipa), Part I (Political History). pgs 19-24. (my comments thereon)
[7.3] Joseph Minattur (1966), “Malaya: What’s in a name?”
E.g. Majumdar suggests that the various Mālayas:
Are related, and that the tribe is of Austro-asiatic, i.e. “Para-Munda” origin.
Fish-eater colonialism: However incredible this claim of a great lost civilization spanning the seas in the LBA/EIA may seem, there is a third context wherein it has independently arisen, namely the early trade between the Indian West coast (both IVC Gujarat and the Konkan, Karnataka) and Sub-Saharan Africa [8x.1] [8x.2] and the mastery over the monsoon winds:
Material cultures: Perhaps we can get some hints from looking at archaeology? Here is a list of material cultures from North India known to archaeologists:
Table S1 of [9x.1]
In the Deccan you have the famous megalithic culture (dolmens and such) and ashmounds, which I cannot even find reliable dating for, and in the Tamil country you have sites at Keezhadi, Adichanallur, Anuradhapura etc. But this is all really disappointingly unexplored and doesn’t help us, though it is notable that the only clear examples we have of material cultures ~1300—800BC outside the Vedic realm are those of Madhya Pradesh, something also attested in e.g. the famous Bhimbetka caves. Indeed, even in the literature one observes the culture of the Pulindas is mentioned somewhat distinctly, e.g. [9x.2].
The Rāmāyaṇa
The Rāmāyaṇa appears to be based on a combination of real events of importance from the 8th or 7th centuries BC as well as an account of information from the earliest Ārya explorations of the peninsula (similar in mystique to e.g. the accounts of Indica by Herodotus or Ctesias). If you accept this general view, then the ambiguous names in the Rāmāyaṇa can be seen as a sample of words or names in the peninsula in those times: Hanumān, Vālī, Rāvaṇa, , Jaṭāyu, Sampāti, Kiṣkindhā, Rumā, Khara (note the name of later Kaliṅga king Kharavela), Mālyavān & related Māli, Mārīca, Śabarī (perhaps from the river Śabarī, a tributary to the Godāvarī), Tāṭakā (the yakṣa).
I think that in cases where a place is said to be named after a character, it is likely to be the reverse. E.g. according to [10x.1], the Śabarī river is named after the “Śabara”, a Telugu people; or the tale of Takṣaka in the Mahābhārata indicating a Nāga culture in Gandhāra before the dominance of the Kurus, or the tale of Mahiṣāsura for Mysore, of Vātāpi, of Śūrpaṇakhā based on the city of Śūrparaka. Their true etymology may lie in some (lost?) peninsular language.
(There have been some claims that the Vālmīki Rāmāyaṇa actually does not refer to an expedition to the South, that Laṅka is actually in Amarakaṇṭaka in Madhya Pradesh and that its identification with Siṃhala comes from the period of the Cōḻa imperialism in the island. This is definitively false: Vālmīki Rāmāyaṇa 4.41 identifies the location of Laṅkā as being in the South, past the Pāṇdya country, opposite the ocean from the Mahendra mountains (Eastern Ghats): this can only be Sri Lanka. Besides, the Rāmāyaṇa is quite explicit in its geography, describing an overall Southern voyage, e.g. Pañcavaṭī forest, the site of Sītā’s abduction, is on the Godāvari river (Vālmīki Rāmāyaṇa 3.64) and probably identifiable as Nashik. In the 4th century, the Laṇkāvatāra Sūtra, a Bauddha text, was composed in Siṃhala itself.)
The culmination of the theology of the previous period is the Br̥haddevatā, c. 500 BC. Subsequently many theological cults developed, some absorbing non-Vedic elements from the Vrātyas, Nāgas etc. some canonizing the songs of bards (the Sūta caste), and some independent developments.
