Shudra in the context of "Varna (Hinduism)"

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.

Christianity is India's third-most followed religion with 28 million adherents, who make up 2.3 percent of the population as of the 2011 census. Christianity is the largest religion in parts of Northeast India, specifically in Nagaland, Mizoram, and Meghalaya. It is also a significant religion in Manipur, which is 41 percent Christian.

Nearly two-thirds (65 percent) of India's Christians are found in South India, Goa, & Mumbai (Bombay). The oldest known Christian group in North India are the Hindustani-speaking Bettiah Christians of Bihar, formed in the early 1700s through a Capuchin mission and under the patronage of Rajas (kings) in the Moghal Empire. The Church of North India and the Church of South India are a United Protestant denomination; which resulted from the evangelism/ ecumenism of Anglicans, Calvinists, Methodists and other Protestant groups who flourished in colonial India. Consequently, these churches are part of the worldwide Anglican Communion, World Communion of Reformed Churches, and World Methodist Council. Along with native Christians, small numbers of mixed Eurasian peoples such as Anglo-Indian, Luso-Indian, Franco-Indian and Armenian Indian Christians also existed in the subcontinent. Also, there is the Khrista Bhakta movement, who are unbaptised followers of Christ and St Mary, mainly among the Shudras and Dalits.

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.
