Historical Vedic religion

The historical Vedic religion, also called Vedism or Brahmanism, and sometimes ancient Hinduism or Vedic Hinduism, constituted the religious ideas and practices prevalent amongst some of the Indo-Aryan peoples of the northwest Indian subcontinent (Punjab and the western Ganges plain) during the Vedic period (c. 1500–500 BCE). These ideas and practices are found in the Vedic texts, and some Vedic rituals are still practised today. The Vedic religion is one of the major traditions which shaped modern Hinduism, though present-day Hinduism is significantly different from the historical Vedic religion.

The Vedic religion has roots in the Indo-Iranian culture and religion of the Sintashta (c. 2200–1750 BCE) and Andronovo (c. 2000–1150 BCE) cultures of Eurasian Steppe. This Indo-Iranian religion borrowed "distinctive religious beliefs and practices" from the non-Indo-Aryan Bactria–Margiana culture (BMAC; 2250–1700 BCE) of south of Central Asia, when pastoral Indo-Aryan tribes stayed there as a separate people in the early 2nd millennium BCE. From the BMAC Indo-Aryan tribes migrated to the northwestern region of the Indian subcontinent, and the Vedic religion developed there during the early Vedic period (c. 1500–1100 BCE) as a variant of Indo-Aryan religion, influenced by the remnants of the late Indus Valley Civilisation (2600–1900 BCE).

During the late Vedic period (c. 1100–500 BCE) Brahmanism developed out of the Vedic religion, as an ideology of the Kuru-Panchala realm which expanded into a wider area after the demise of the Kuru-Pancala realm and the domination of the non-Vedic Magadha cultural sphere. Brahmanism was one of the major influences that shaped contemporary Hinduism, when it was synthesized with the non-Vedic Indo-Aryan religious heritage of the eastern Ganges plain (which also gave rise to Buddhism and Jainism), and with local religious traditions.

Specific rituals and sacrifices of the Vedic religion include, among others: the Soma rituals; fire rituals involving oblations (havir); and the Ashvamedha (horse sacrifice). The rites of grave burials as well as cremation are seen since the Rigvedic period. Deities emphasized in the Vedic religion include Dyaus, Indra, Agni, Rudra and Varuna, and important ethical concepts include satya and ṛta.

Vedism refers to the oldest form of the Vedic religion, when Indo-Aryans entered into the valley of the Indus River in multiple waves during the 2nd millennium BCE. Brahmanism refers to the further developed form of the late Vedic period which took shape at the Ganges basin around c. 1000 BCE. According to Heesterman, "It is loosely known as Brahmanism because of the religious and legal importance it places on the brāhmaṇa (priestly) class of society." During the late Vedic period, the Brahmanas and early Upanishads were composed. Both Vedism and Brahmanism regard the Veda as sacred, but Brahmanism is more inclusive, incorporating doctrines and themes beyond the Vedas with practices like temple worship, puja, meditation, renunciation, vegetarianism, the role of the guru, and other non-Vedic elements important to Hindu religious life.

The terms ancient Hinduism and Vedic Hinduism have also been used when referring to the ancient Vedic religion.

According to Heinrich von Stietencron, in 19th century western publications, the Vedic religion was believed to be different from and unrelated to Hinduism. Instead, Hinduism was thought to be linked to the Hindu epics and the Puranas through sects based on purohita, tantras and Bhakti. In response to western colonialism and (Protestant) proselytizing, Hindu reform movements like the Brahmo Samaj and the Neo-Vedanta in the late 19th and early 20th century rejected the 'superstitions' of Puranic Hinduism, which in their view had deviated from the Vedic heritage, instead propagating a return to the Vedas and to restore an "imagined" original, rational and monotheistic ancient Hinduism with an equal standing as Protestant Christianity.

In the 20th century, the neo-Hindu emphasis on Vedic roots, and a better understanding of the Vedic religion and its shared heritage and theology with contemporary Hinduism, led scholars to view the historical Vedic religion as ancestral to modern Hinduism. The historical Vedic religion is now generally accepted to be a predecessor of modern Hinduism, but they are not the same because the textual evidence suggests significant differences between the two. These include the belief in an afterlife instead of the later developed reincarnation and samsāra concepts.^{[page needed]} Nevertheless, while "it is usually taught that the beginnings of historical Hinduism date from around the beginning of the Common Era," when "the key tendencies, the crucial elements that would be encompassed in Hindu traditions, collectively came together," some scholars have come to view the term "Hinduism" as encompassing Vedism and Brahmanism, in addition to the recent synthesis.
