Vedic period
The Vedic period, or the Vedic age, is the period in the late Bronze Age and early Iron Age of the history of India when the Vedic literature, including the Vedas, was composed in the northern Indian subcontinent, between the end of the urban Indus Valley Civilisation and a second urbanisation, which began in the central Indo-Gangetic Plain BCE. The Vedas are liturgical texts which formed the basis of the influential Brahmanical ideology, which developed in the Kuru kingdom, a tribal union of several Indo-Aryan tribes. The Vedas contain details of life during this period that have been interpreted to be historical and constitute the primary sources for understanding the period. These documents, alongside the corresponding archaeological record, allow for the evolution of the Indo-Aryan and Vedic culture to be traced and inferred.
The Vedas were composed and orally transmitted with precision by speakers of an Old Indo-Aryan language who had migrated into the northwestern regions of the Indian subcontinent early in this period. The Vedic society was patriarchal and patrilineal. Early Indo-Aryans were a Late Bronze Age society centred in the Punjab, organised into tribes rather than kingdoms, and primarily sustained by a pastoral way of life.
Around –1000 BCE the Aryan culture spread eastward to the fertile western Ganges Plain. Iron tools were adopted, which allowed for the clearing of forests and the adoption of a more settled, agricultural way of life. The second half of the Vedic period was characterised by the emergence of towns, kingdoms, and a complex social differentiation distinctive to India, and the Kuru kingdom's codification of orthodox sacrificial ritual. During this time, the central Ganges Plain was dominated by a related but non-Vedic Indo-Aryan culture, of Greater Magadha. The end of the Vedic period witnessed the rise of true cities and large states as well as śramaṇa movements which challenged the Vedic orthodoxy.
The Vedic period saw the emergence of a hierarchy of social classes that would remain influential. Vedic religion developed into Brahmanical orthodoxy, and around the beginning of the Common Era, the Vedic tradition formed one of the main constituents of "Hindu synthesis".
Archaeological cultures identified with phases of Indo-Aryan material culture include the Ochre Coloured Pottery culture, the Gandhara grave culture, the Black and Red ware culture and the Painted Grey Ware culture.
History
Origins
The early Vedic age is historically dated to the second half of the second millennium BCE. Historically, after the collapse of the Indus Valley Civilisation, which occurred around 1900 BCE, groups of Indo-Aryan peoples migrated into north-western India and started to inhabit the northern Indus Valley. The Indo-Aryans represented a sub-group that diverged from other Indo-Iranian tribes at the Andronovo horizon before the middle of the 2nd millennium BCE. The Indo-Iranians originated in the Sintashta culture, from which arose the subsequent Andronovo horizon. The Indo-Aryans migrated through the adjacent Bactria–Margiana area to northwest India, followed by the rise of the Iranian Yaz culture at 1500 BCE, and the Iranian migrations into Iran at 800 BCE.File:Indo-Iranian origins.png|thumb|left|Archaeological cultures associated with Indo-Iranian migrations. The Andronovo, BMAC and Yaz cultures have often been associated with Indo-Iranian migrations. The GGC, Cemetery H, Copper Hoard and PGW cultures are candidates for cultures associated with Indo-Aryan movements.
Some Indian writers and archaeologists have opposed the notion of a migration of Indo-Aryans into India, and argued for an indigenous origin of the Indo-Aryans. In this view, "the Indian civilization must be viewed as an unbroken tradition that goes back to the earliest period of the Sindhu-Sarasvati tradition." Though popular in India, and reflecting Indian views on Indian history and religion, the idea of a purely indigenous origin of the Indo-Aryans is outside the academic mainstream.
The knowledge about the Aryans comes mostly from the Rigveda-samhita, i.e. the oldest layer of the Vedas, which was composed 1400–1000 BCE. They brought with them their distinctive religious traditions and practices. The Vedic beliefs and practices of the pre-classical era were closely related to the hypothesised Proto-Indo-European religion and the Indo-Iranian religion. Funeral sacrifices from the Sintashta culture show close parallels to the sacrificial funeral rites of the Rigveda, while, according to Anthony, the Old Indic religion probably emerged among Indo-European immigrants in the contact zone between the Zeravshan River and Tajikistan. It was "a syncretic mixture of old Central Asian and new Indo-European elements", which borrowed "distinctive religious beliefs and practices" from the Bactria–Margiana culture, including the god Indra and the ritual drink Soma.
Early Vedic period (c. 1500 BCE – c. 1000 BCE)
The Rigveda contains accounts of conflicts between the Aryas and the Dasas and Dasyus. It describes Dasas and Dasyus as people who do not perform sacrifices or obey the commandments of gods. Their speech is described as mridhra which could variously mean soft, uncouth, hostile, scornful or abusive. Other adjectives which describe their physical appearance are subject to many interpretations. However, some modern scholars such as Asko Parpola connect the Dasas and Dasyus to Iranian tribes Dahae and Dahyu and believe that Dasas and Dasyus were early Indo-Aryan immigrants who arrived into the subcontinent before the Vedic Aryans. Likewise, Bronkhorst has argued that the central Ganges Plain was dominated by a related but non-Vedic Indo-Aryan culture, a difference also noted by Samuel.Accounts of military conflicts in between the various tribes of Vedic Aryans are also described in the Rigveda. Most notable of such conflicts was the Battle of the Ten Kings, which took place on the banks of the river Parushni. The battle was fought between the tribe Bharatas, led by their chief Sudas, against a confederation of ten tribes. The Bharatas lived around the upper regions of the river Saraswati, while the Purus, their western neighbours, lived along the lower regions of Saraswati. The other tribes dwelt north-west of the Bharatas in the region of Punjab. Division of the waters of Ravi could have been a reason for the war. The confederation of tribes tried to inundate the Bharatas by opening the embankments of Ravi, yet Sudas emerged victorious in the Battle of Ten Kings. The Bharatas and the Purus merged into a new tribe, the Kuru, after the war.
Later Vedic period (c. 1000 – c. 600 BCE)
After the 12th century BCE, as the Rigveda had taken its final form, the Vedic society, which is associated with the Kuru-Panchala region but were not the only Indo-Aryan people in northern India, transitioned from semi-nomadic life to settled agriculture in north-western India. Possession of horses remained an important priority of Vedic leaders and a remnant of the nomadic lifestyle, resulting in trade routes beyond the Hindu Kush to maintain this supply as horses needed for cavalry and sacrifice could not be bred in India. The Gangetic plains had remained out of bounds to the Vedic tribes because of thick forest cover. After 1000 BCE, the use of iron axes and ploughs became widespread and the jungles could be cleared with ease. This enabled the Vedic Aryans to extend their settlements into the western area of the Ganga-Yamuna Doab. Many of the old tribes coalesced to form larger political units.The Vedic religion was further developed with the emergence of the Kuru kingdom, systematising its religious literature and developing the Śrauta ritual. It is associated with the Painted Grey Ware culture, which did not expand east of the Ganga-Yamuna Doab. It differed from the related, yet markedly different, culture of the Central Ganges region, which was associated with the Northern Black Polished Ware and the Mahajanapadas of Kosala and Magadha.
In this period the varna system emerged, state Kulke and Rothermund, which in this stage of Indian history were a "hierarchical order of estates which reflected a division of labor among various social classes". The Vedic period estates were four: Brahmin priests and warrior nobility stood on top, free peasants and traders were the third, and slaves, labourers and artisans, many belonging to the pre-Aryan groups, were the fourth. This was a period where agriculture, metal, and commodity production, as well as trade, greatly expanded, and the Vedic era texts including the early Upanishads and many Sutras important to later Hindu culture were completed.

The Kuru kingdom, the earliest Vedic "state", was formed by a "super-tribe" which joined several tribes in a new unit. To govern this state, Vedic hymns were collected and transcribed, and new rituals were developed, which formed the now orthodox Śrauta rituals. Two key figures in this process of the development of the Kuru state were the king Parikshit and his successor Janamejaya, transforming this realm into the dominant political and cultural power of northern Iron Age India.
The most well-known of the new religious sacrifices that arose in this period were the Ashvamedha. This sacrifice involved setting a consecrated horse free to roam the kingdoms for a year. The horse was followed by a chosen band of warriors. The kingdoms and chiefdoms in which the horse wandered had to pay homage or prepare to battle the king to whom the horse belonged. This sacrifice put considerable pressure on inter-state relations in this era. This period saw also the beginning of the social stratification by the use of varna, the division of Vedic society into Brahmins, Kshatriya, Vaishya and Shudra.
The Kuru kingdom declined after its defeat by the non-Vedic Salva tribe, and the political center of Vedic culture shifted east, into the Panchala kingdom on the Ganges, under King Keśin Dālbhya. Later, in the 8th or 7th century BCE, the kingdom of Videha emerged as a political center farther to the East, in what is today northern Bihar of India and southeastern Nepal, reaching its prominence under the king Janaka, whose court provided patronage for Brahmin sages and philosophers such as Yajnavalkya, Uddalaka Aruni, and Gargi Vachaknavi; Panchala also remained prominent during this period, under its king Pravahana Jaivali.
