History of Hinduism

The history of Hinduism covers a wide variety of related religious traditions native to the Indian subcontinent. It overlaps or coincides with the development of religion in the Indian subcontinent since the Iron Age, with some of its elements possibly tracing back to prehistoric religions such as those of the Bronze Age Indus Valley Civilisation. Hinduism has been called the "oldest religion" in the world, but scholars regard Hinduism as a relatively recent synthesis of various Indian cultures and traditions, with diverse roots and no single founder, which emerged around the beginning of the Common Era.

The history of Hinduism is often divided into periods of development. The first period is the pre-Vedic period, which includes the Indus Valley Civilization and local pre-historic religions. Northern India had the Vedic period with the introduction of the historical Vedic religion by the Indo-Aryan migrations, starting somewhere between 1900 BCE and 1400 BCE. The subsequent period of the second urbanisation (600–200 BCE) is a formative period for Hinduism, Jainism and Buddhism followed by "a turning point between the Vedic religion and Hindu religions," during the Epic and Early Puranic period ( to 500 CE), when the Epics and the first Purānas were composed. This was followed by the classical "Golden Age" of Hinduism (–650 CE), which coincides with the Gupta Empire. In this period the six branches of Hindu philosophy evolved, namely, Samkhya, Yoga, Nyaya, Vaisheshika, Mīmāṃsā, and Vedānta. Monotheistic sects like Shaivism and Vaishnavism developed during this same period through the Bhakti movement. It flourished in the medieval period from roughly 650 to 1100 CE, which forms the late Classical period or early Middle Ages,

with the decline of Buddhism in India and the establishment of classical Puranic Hinduism is established.

Hinduism under both Hindu and Islamic rulers from to 1750 CE saw the increasing prominence of the Bhakti movement, which remains influential today. Adi Shankara became glorified as the main proponent of Advaita Vedanta, in response to the success of Vaishnavite bhakti.

The colonial period saw the emergence of various Hindu reform movements partly inspired by western movements, such as Unitarianism and Theosophy. The Partition of India in 1947 was along religious lines, with the Republic of India emerging with a Hindu majority. During the 20th century, due to the Indian diaspora, Hindu minorities have formed in all continents, with the largest communities in absolute numbers in the United States and the United Kingdom.

Roots of Hinduism

While the Puranic chronology presents a genealogy of thousands of years, scholars regard Hinduism as a fusion, synthesis, or amalgamation of various Indian cultures and traditions.

Among its roots are the historical Vedic religion, itself already the product of "a composite of the Indo-Aryan and Harappan cultures and civilizations", which evolved into the Brahmanical religion and ideology of the Kuru kingdom of Iron Age northern India; but also the Śramaṇa or renouncer traditions of northeast India, and mesolithic and neolithic cultures of India, such as the religions of the Indus Valley Civilisation, Dravidian traditions, and the local traditions and tribal religions.

This Hindu synthesis emerged after the Vedic period, between 500–200 BCE and , in the period of the second urbanisation and the early classical period of Hinduism, when the Epics and the first Puranas were composed. This Brahmanical synthesis incorporated śramaṇic and Buddhist influences and the emerging bhakti tradition into the Brahmanical fold via the smriti literature. This synthesis emerged under the pressure of the success of Buddhism and Jainism, starting with the conquest of the Vedic heartland by the Nanda and Maurya rulers, which deprived the Brahmins of their patrons, threatening the survival of the Vedic ritual tradition. In response, Brahmins broadened their services, eventually resulting in the Hindu synthesis of Brahmanical orthodoxy with local religious traditions, which, centuries later, came to dominate India. During the Gupta reign the first Puranas were written, which were used to disseminate "mainstream religious ideology amongst pre-literate and tribal groups undergoing acculturation." The resulting Puranic Hinduism differed markedly from the earlier Brahmanism of the Dharmasutras and the smritis. Hinduism co-existed for several centuries with Buddhism, to finally gain the upper hand at all levels in the 8th century.
