Untouchability, in its literal sense, is the practice of ostracising a minority group by segregating them from the mainstream by social custom or legal mandate.
The term is most commonly associated with treatment of the Dalit communities in the Indian subcontinent who were considered "polluting". The term has also been used to refer to other groups, including the Burakumin of Japan, the Baekjeong of Korea, and the Ragyabpa of Tibet, as well as the Romani people and Cagot in Europe, and the Al-Akhdam in Yemen Traditionally, the groups characterized as untouchable were those whose occupations and habits of life involved ritually "polluting" activities, such as fishermen, manual scavengers, sweepers and washermen. In the medieval times, untouchables were also those who had eating habits like eating dead animals with diseases, in contrast to groups who supposedly followed higher standards of cleanliness.
Untouchability has been outlawed in India, Nepal and Pakistan. However, "untouchability" has not been legally defined. The origin of untouchability and its historicity are still debated. B. R. Ambedkar believed that untouchability has existed at least as far back as 400 AD. A recent study of a sample of households in India concludes that "Notwithstanding the likelihood of under-reporting of the practice of untouchability, 70 percent of the population reported not indulging in this practice. This is an encouraging sign."
B. R. Ambedkar, an Indian social reformer and politician who came from a social group that was considered untouchable, theorized that untouchability originated because of the deliberate policy of the upper-caste Brahmanas. According to him, the Brahmanas despised the people who gave up the Brahmanism in favour of Buddhism. Later scholars such as Vivekanand Jha have successfully refuted this theory.
Nripendra Kumar Dutt, a professor of history, theorized that the concept of untouchability originated from the "pariah"-like treatment accorded to the aboriginies of India by the early Dravidians, and that the concept was borrowed by the Indo-Aryans from the Dravidians. Scholars such as R. S. Sharma have rejected this theory, arguing that there is no evidence that Dravidians practised untouchability before coming into contact with the Indo-Aryans.
Austrian ethnologist Christoph von Fürer-Haimendorf theorized that untouchability originated as class stratification in urban areas of the Indus Valley Civilisation. According to this theory, the poorer workers involved in 'unclean' occupations such as sweeping or leather work were historically segregated and banished outside the city limits. Over time, personal cleanliness came to be identified with "purity", and the concept of untouchability eventually spread to rural areas as well. After the decline of the Indus Valley towns, these untouchables probably spread to other parts of India. Scholars such as Suvira Jaiswal reject this theory, arguing that it lacks evidence, and does not explain why the concept of untouchability is more pronounced in rural areas.
American scholar George L. Hart, based on his interpretation of Old Tamil texts such as Purananuru, traced the origin of untouchability to ancient Tamil society. According to him, in this society, certain occupational groups were thought to be involved in controlling the malevolent supernatural forces; as an example, Hart mentions the Paraiyars, who played drums during battles and solemn events such as births and deaths. People from these occupational groups came to be avoided by others, who believed that they were "dangerous and had the power to pollute the others". Jaiswal dismisses the evidence produced by Hart as "extremely weak" and contradictory. Jaiswal points out that the authors of the ancient Tamil texts included several Brahmanas (a fact accepted by Hart); thus, the society described in these texts was already under Brahmanical influence, and could have borrowed the concept of untouchability from them.
English merchant William Methwold who visited India during early seventeenth century says that he found certain castes who followed vegetarian diet, who had high standards of cleanliness practices he also found untouchable castes were those who ate dead animals even those with diseases. British anthropologist John Henry Hutton traced the origin of untouchability to the taboo on accepting food cooked by a person from a different caste. This taboo presumably originated because of cleanliness concerns, and ultimately, led to other prejudices such as the taboo on marrying outside one's caste. Jaiswal argues that this theory cannot explain how various social groups were isolated as untouchable or accorded a social rank. Jaiswal also notes that several passages from the ancient Vedic texts indicate that there was no taboo against accepting food from people belonging to a different varna or tribe. For example, some Shrauta Sutras mandate that a performer of the Vishvajit sacrifice must live with the Nishadas (a tribe regarded as untouchable in later period) for three days, in their village, and eat their food.
Scholars such as Suvira Jaiswal, R. S. Sharma, and Vivekanand Jha characterize untouchability as a relatively later development after the establishment of the varna and caste system. Jha notes that the earliest Vedic text Rigveda makes no mention of untouchability, and even the later Vedic texts, which revile certain groups such as the Chandalas, do not suggest that untouchability existed in the contemporary society. According to Jha, in the later period, several groups began to be characterized as untouchable, a development which reached its peak during 600–1200 AD. Sharma theorizes that institution of untouchability arose when the aboriginal tribes with "low material culture" and "uncertain means of livelihood" came to be regarded as impure by the privileged classes who despised manual labour, and regarded associated impurity with "certain material objects". According to Jaiswal, when the members of aboriginal groups were assimilated into the Brahmanical society, the privileged among them may have tried to assert their higher status by disassociating themselves from their lower-status counterparts, who were gradually branded as untouchables.
Untouchability is believed to have been first mentioned in Dharmashastra. According to the text, untouchables were not considered a part of the varna system because of their grievous sins, barbaric or unethical acts such as murder, harassment etc. Therefore, they were not treated like the savarnas (Brahmins, Kshatriyas, Vaishyas and Shudras).[page needed]
According to Sarah Pinto, an anthropologist, modern untouchability in India applies to people whose work relates to "meat, and bodily fluids". Based on the punishments prescribed in The Untouchability (Offences) Act, 1955 the following practices could be understood to have been associated with Untouchability in India:
At the time of Indian independence, Dalit activists began calling for separate electorates for untouchables in India to allow fair representation. Officially labeled the Minorities Act, it would guarantee representation for Sikhs, Muslims, Christians, and Untouchables in the newly formed Indian government. The Act was supported by British representatives such as Ramsay MacDonald. According to the textbook Religions in the Modern World, B. R. Ambedkar, who was also a supporter of the Act, was considered to be the “untouchable leader” who made great efforts to eliminate caste system privileges that included participation in public festivals, access to temples, and wedding rituals. In 1932, Ambedkar proposed that the untouchables create a separate electorate that ultimately led Gandhi to fast until it was rejected.
A separation within Hindu society was opposed by national leaders at the time such as Gandhi, although he took no exception to the demands of the other minorities. He began a hunger strike to protest this type of affirmative action, citing that it would create an unhealthy divide within the religion. At the Round Table Conferences, he provided this explanation for his reasoning:
I don't mind untouchables if they so desire, being converted to Islam or Christianity. I should tolerate that, but I cannot possibly tolerate what is in store for Hinduism if there are two divisions set forth in the villages. Those who speak of the political rights of the untouchables don't know their India, don't know how Indian society is today constituted and therefore I want to say with all the emphasis that I can command that if I was the only person to resist this thing that I would resist it with my life.
Gandhi achieved some success through his hunger strike. Dalit activists faced pressure from the Hindu population at large to end his protest at the risk of his ailing health. The two sides eventually came to a compromise where the number of guaranteed seats for Untouchables would be increased at both central and provincial levels, but there would be a common electorate.
The 1950 national constitution of India legally abolished the practice of untouchability and provided measures for positive discrimination in both educational institutions and public services for Dalits and other social groups who lie within the caste system. These are supplemented by official bodies such as the .
Despite this, instances of prejudice against Dalits still occur in some rural areas, as evidenced by events such as the Kherlanji massacre.
