Āryāvarta

Āryāvarta is a term for the northern Indian subcontinent in the ancient Hindu texts such as Dharmashastras and Sutras, referring to the areas of the Indo-Gangetic Plain and surrounding regions settled during and after the Indo-Aryan migrations by Indo-Aryan tribes and where Indo-Aryan religion and rituals predominated. The limits of Āryāvarta extended over time, as reflected in the various sources, as the influence of the Brahmanical ideology spread eastwards in post-Vedic times.

Geographical boundaries

Ganges-Yamuna doab

The Baudhayana Dharmasutra 1.1.2.10 declares that Āryāvarta is the land that lies west of Kālakavana, east of Adarsana, south of the Himalayas and north of the Vindhyas, but in BDS 1.1.2.11 Āryāvarta is confined to the doab of the Ganges-Yamuna. BDS 1.1.2.13-15 considers people from beyond this area as of mixed origin, and hence not worthy of emulation by the Aryans. Some sutras recommend expiatory acts for those who have crossed the boundaries of Aryavarta. Baudhayana Srautasutra recommends this for those who have crossed the boundaries of Aryavarta and ventured into far away places.
The Vasistha Dharma Sutra I.8-9 and 12-13 locates the Āryāvarta to the east of the disappearance of the Sarasvati River in the desert, to the west of the Kālakavana, to the north of the Pariyatra Mountains and the Vindhya Range and to the south of the Himalayas.
Patanjali's defines Āryāvarta like the Vashistha Dharmasutra. According to Bronkhost, he "situates it essentially in the Ganges plan, between the Thar Desert in the west and the confluence of the rivers Ganges and Jumna in the east."

From sea to sea

The Manusmṛti gives the name to "the tract between the Himalaya and the Vindhya Ranges, from the Eastern Sea to the Western Sea ".
The Manava Dharmasastra gives aryavarta as stretching from the eastern to the western seas, which Bronkhorst directly associates with the growing sphere of influence of the Brahmanical ideology.

Greater Magadha and its association with Aryavarta

Following the description of Aryavarta in early Brahmanical sources, Bronkhorst notes that the Greater Magadha area was outside Aryavarta, the heartland of Vedic Brahmanism, and proposes that "Greater Magadha" had a distinct culture. According to Bronkhorst, Aryavarta was primarily associated with a single state, the Kuru kingdom. According to Bronkhorst, the various emperors of Magadha had little interest in Brahmanism, and the conquest of the Vedic heartland by the Nanda and Maurya rulers deprived the Brahmins of their patrons, threatening the survival of the Vedic ritual tradition and creating opportunities for Buddhists and Jains to spread their religions outside the confines of Magadha. According to Bronkhorst, the Brahmins overcame their deprivation of patrons by providing new services and by incorporating the non-Vedic Indo-Aryan religious heritage of the eastern Ganges plain along with local religious traditions, giving rise to the Hindu synthesis.
Geoffrey Samuel, following Thomas Hopkins, also proposed that the Central Gangetic region formed a "distinct but related cultural complex," as exemplified by the Painted Grey Ware, which did not spread past the Ganga-Yamuna Doab. It was the area of the earliest known rice cultivation in South Asia, and had reached the Chalcolithic when the Aryans first entered northwestern India. According to Hopkins, the Aryan societies and this eastern Gangetic culture formed two separate sources for the development toward iron-working and urbanisation. According to Hopkins, the Brahmins of the Aryan, Vedic cultural sphere perceived this eastern, non-Aryan, Jain-Buddhist cultural sphere as wholly different, with a "world of female powers, natural transformation, sacred earth and sacred places, blood sacrifices, and ritualists who accept pollution on behalf of their community." Yet, Samuel notes that the distinction "was cultural, not racial," assuming that "populations in both regions were mixtures of earlier Indo-Aryan and non-Indo-Aryan speaking populations." While forming different cultural spheres, they also interacted, and shared some common Indo-Aryan elements."
Critics have questioned some of these assertions. The claim of a sharp cultural divide between east and west was questioned by Konrad Klaus in his 2011 review of "Greater Magadha." According to Norelius, Wynne and Witzel questioned the supposed lesser influence of Brahmanisation in early Magadha, or Bronkhorst's proposed revision of textual chronology, while Fynne criticised Bronkhorst for overlooking the role of socioeconomic and political developments in shaping new ideological trends.
In his 2011 review, Wynne calls Bronkhorst's argument "compelling" and "persuasive," but also notes that "Bronkhorst argues that the ideas of karma, rebirth, and liberation originated within Greater Magadha," proposing later dates for some Upanishads to make this possible. Yet according to Wynne, "his is problematic, however, because these ideas are stated in the Bṛhadāraṇyaka and Chāndogya Upaniṣads--texts usually assigned to the sixth or fifth century BCE, early enough to suppose an origin within the sphere of Vedic religion." Instead, Wynne proposes that the Yājñavalkya-kāṇḍa was composed in the Videha-Kosala region by a Vedic school which was isolated from the Vedic mainstream, circulated as a separate work outside Aryavarta, and "was an important source for the ideas of karma, rebirth, and liberation," "eventually trigger the culture of world renunciation, asceticism, and meditation" as an "unintended consequence of the early Videhan kings’ attempt to legitimize their rule through the Vedic tradition."
Additionally, Patrick Olivelle, writing in 1993, is critical of scholars who portray the Śramaṇa seers of Magadha as non-Brahmanical, anti-Brahmanical, or even non-Aryan precursors of later sectarian ascetics. According to Olivelle, scholars who attempt to draw such sharp divisions are reaching conclusions that far exceed the available empirical evidence.

Other regional designations

The Manusmṛti mentions Brahmavarta as the region between the Sarasvati and the Drishadvati in northwest India. The text defines the area as the place where the "good" people are born, the twice-born who adhere to the Vedic dharma, in contrast to the mlecchas, who live outside the Aryan territory and Vedic traditions. The precise location and size of the region has been the subject of academic uncertainty. Some scholars, such as the archaeologists Bridget Allchin and Raymond Allchin, believe the term Brahmavarta to be synonymous with Aryavarta.
Madhyadesa extended from the upper reaches of the Ganges and the Yamuna to the confluence of the two rivers at Prayaga, and was the region where, during the time of the Mahajanapadas, the Kuru kingdom and Pañcāla existed. The entire region is considered sacred in the Hindu mythology as gods and heroes mentioned in the two epics, the Ramayana and Mahabharata, lived here.

Political history

or modern day Kannauj was a central city of Aryavarta and was used as capital-city from 510 CE to 1197 CE under Maukharis, Harshavardhana, Varmans, Pratiharas and Gahadavala dynasty.
The Gurjara-Pratihara king in the tenth century was titled the Maharajadhiraja of Aryavarta. Devapala, the emperor of Pala Empire was known to be the Overlord of Aryavarta.
