Varna (Hinduism) in the context of "History of India"

In India, social classification based on caste has its origin in ancient times. It was transformed by various ruling elites in medieval, early-modern, and modern India, especially in the aftermath of the collapse of the Mughal Empire and the establishment of the British Raj. Caste is traditionally associated with Hinduism, but is more pervasive in extent: an estimated 98% of contemporary Indians, including Hindus, Muslims, Christians, Sikhs, Buddhists, and Jains, identify with a caste.

Beginning in ancient India, the caste system was originally centered around varna, with Brahmins (priests) and, to a lesser extent, Kshatriyas (rulers and warriors) serving as the elite classes, followed by Vaishyas (traders and merchants) and finally Shudras (labourers). Outside of this system are the oppressed, marginalised, and persecuted Dalits (also known as "Untouchables") and Adivasis (tribals). Over time, the system became increasingly rigid, and the emergence of jati led to further entrenchment, introducing thousands of new castes and sub-castes. With the arrival of Islamic rule, caste-like distinctions were formulated in certain Muslim communities, primarily in North India. The British Raj furthered the system, through census classifications and preferential treatment to Christians and people belonging to certain castes. Social unrest during the 1920s led to a change in this policy towards affirmative action.

Brahmin (/ˈbrɑːmɪn/; Sanskrit: ब्राह्मण, romanized: brāhmaṇa) is a varna (theoretical social classes) within Hindu society. The other three varnas are the Kshatriya (rulers and warriors), Vaishya (traders, merchants, and farmers), and Shudra (labourers). The traditional occupation of Brahmins is that of priesthood (purohit, pandit, or pujari) at Hindu temples or at socio-religious ceremonies, and the performing of rite of passage rituals, such as solemnising a wedding with hymns and prayers.

Traditionally, Brahmins are accorded the supreme ritual status of the four social classes, and they also served as spiritual teachers (guru or acharya). In practice, Indian texts suggest that some Brahmins historically also became agriculturalists, warriors, traders, and had also held other occupations in the Indian subcontinent. Within the jati (caste) system, Brahmins similarly occupy the highest position, though that is complicated by strict stratification even among Brahmins and historical attempts by other castes and sub-castes to challenge Brahminical dominance.

Kshatriya (Sanskrit: क्षत्रिय, romanized: Kṣatriya) (from Sanskrit kṣatra, "rule, authority"; also called Rajanya) is one of the four varnas (social orders) of Hindu society and is associated with the warrior aristocracy. The Sanskrit term kṣatriyaḥ is used in the context of later Vedic society wherein members were organised into four classes: brahmin, kshatriya, vaishya, and shudra.

Vaishya (Sanskrit: वैश्य, vaiśya) is one of the four varnas of the Vedic Hindu social order in India. Vaishyas are classed third in the order of Varna hierarchy.

The occupation of Vaishyas consists mainly of agriculture, taking care of cattle, trade and other business pursuits as mentioned in the Bhagavad Gita.

Shudra or Shoodra (Sanskrit: Śūdra) is one of the four varnas of the Hindu class and social system in ancient India. Some sources translate it into English as a caste, or as a social class. Theoretically, Shudras constituted a class like workers.

According to Richard Gombrich's study of Buddhist texts, particularly relating to castes in Sri Lankan Buddhist and Tamil Hindu society,

Newar (/nɪˈwɑːr/; Newar: नेवार, endonym: Newa; Newar: नेवा, Pracalit script: 𑐣𑐾𑐰𑐵𑑅‎), or Nepami, are primarily inhabitants in Kathmandu Valley of Nepal and its surrounding areas, and the creators of its historic heritage and civilisation. Newars are a distinct linguistic and cultural group, primarily Indo-Aryan and Tibeto-Burman ethnicities, who share a common language, Nepal Bhasa, and predominantly practice Newar Hinduism and Newar Buddhism.Newars have developed a division of labour and a sophisticated urban civilisation not seen elsewhere in the Himalayan foothills. Newars have continued their age-old traditions and practices and pride themselves as the true custodians of the religion, culture and civilisation of Nepal. Newars are known for their contributions to culture, art and literature, trade, agriculture and cuisine. Today, they consistently rank as the most economically and socially advanced community in Nepal, according to the annual Human Development Index published by UNDP. Newars are ranked the 8th largest ethnic group in Nepal according to the 2021 Nepal census numbering 1,341,363 people constituting 4.6% of the total population.

The Kathmandu Valley and surrounding territories constituted the former Newar kingdom of the Nepal Mandala. Unlike other common-origin ethnic or caste groups in Nepal, the Newars are regarded as an example of a nation community with a relict identity, derived from an ethnically diverse, previously existing polity. The Newar community within it consists of various strands of ethnic, racial, caste and religious heterogeneity, as they are the descendants of the diverse group of people that have lived in Nepal Mandala since prehistoric times. Indo-Aryan tribes like Maithils of Madhesh Province, the Licchavis, Kosala, and Mallas (N) from respective Indian Mahajanapada (i.e. Licchavis of Vajji, Kosala, and Malla (I)) that arrived at different periods eventually merged with the local native population by marriage as well as adopting their language and customs. These tribes however retained their Vedic culture and brought with them their Sanskritic languages, social structure, Hindu religion and culture, which were assimilated with local cultures and gave rise to the current Newar civilisation. Newar rule in Nepal Mandala ended with its conquest by the Gorkha Kingdom in 1768.

Dharmaśāstra (Sanskrit: धर्मशास्त्र) are Sanskrit Puranic Smriti texts on law and conduct, and refer to treatises (śāstras) on Dharma. Like the Dharmasūtras which are based upon the Vedas, these texts are also elaborate law commentaries based on the Vedas, and evolved from Dharmasutras. There are many Dharmaśāstras, variously estimated to number from 18 to over 100. Each of these texts exists in many different versions, and each is rooted in Dharmasutra texts dated to the 1st millennium BCE that emerged from Kalpa (Vedanga) studies in the Vedic era.

The textual corpus of Dharmaśāstra were composed in poetic verse, and are part of the Hindu Smritis, constituting divergent commentaries and treatises on ethics particularly duties, and responsibilities to oneself and family as well as those required as a member of society. The texts include discussion of ashrama (stages of life), varna (social classes), purushartha (proper goals of life), personal virtues and duties such as ahimsa (non-violence) against all living beings, rules of just war, and other topics.

A Hindu priest may refer to either of the following

• A Pujari or an Archaka is a Hindu temple priest.

• A Purohita or Pujari officiates and performs rituals and ceremonies, and is usually linked to a specific family or, historically, a dynasty.

Traditionally, priests have predominantly come from the Brahmin varna, whose male members are designated for the function in the Hindu texts.
