Religiously anyone who does not belong to the four Varnas is an outcast and untouchable. It means, all foreigners and non-Hindus are all supposed to be untouchables. But in reality neither all foreigners nor non-Hindus were treated as untouchables. Foreigners and non-Hindus were treated differently in different parts of India. Some of the foreigners adopted Hinduism and integrated in the upper level of the Hindu hierarchy.
The Rajputs of Rajasthan belong to the Kshatria Varna (warrior castes). The Rajputs, more than any other Indian Jat, represent the warrior castes of India. Almost any Indian community which claims to be a warrior community, claims a Rajput ancestry. But it is believed that many foreign invaders of ancient India (see- India in the past), like Scythians; Huns; Greeks and others, who adopted Hinduism, integrated in the Rajput community and acquired a Kshatria status (see also Sati - burning of the widow).
The Konkanash Brahmans of west India are also believed to have non- Indian descent. According to a Hindu legend, an incarnation of Lord Vishnu, Parsuram, found on the Konkan beach some dead bodies which were washed to the shore. In order to cremate them Parsuram gathered them on a pyre. These dead bodies woke up on pyre, probably because they were not dead in the first place but were only unconscious. Parsuram converted these people to Hinduism and made them Brahmans. There are other theories about the origins of these Kokanasth Brahmans. Many of these Brahmans have gray-green eyes. Some claim them to be Vikings or of other European origin. In the Konkan coast there is Jewish community called Bene Israel. Some claim that these Jews are from the 'Lost Tribes'. These Jews who arrived in India after their ship-wrecked near the Konkan coast claim that they and the Kokanastha Brahmans are descendants of the survivals from the same ship. And in their version, it was not an incarnation of Lord Vishnu who converted the Kokanastha Brahmans but a local Brahman. Anyway these Jews do not have gray-green eyes like the Kokanastha Brahmans.
Different religion followers got different status in different parts of India. The Jews of west India (called Bene Israel) had a different status from Jews of south India (Cochini Jews). The Bene Israels professed oil pressing and they had a status equal to a Hindu Jat called Somwar Teli, which also professed oil pressing and were part of Sudra Varna. Some orthodox Hindus treated anyone who wasn't one of them as untouchable and therefore treated the Jews also as untouchables. But even though the Jews in west India had low status there were among them some who were landlords, businessmen and high rank officers in local armies.
Comparing to the Bene Israels, the Jews in south India had higher status. The Jews in Kerala were the business community of Kerala. They even ruled a small principality. They had aristocratic rights, such as use of elephants and sedans. They even had servants whose job was to announce their coming to the streets so that the low castes could move away from their way.
The relations between the Jewish communities of India are sometimes explained as affected by the Indian caste system but these relations can also be explained according to Jewish religious laws. There were three main Jewish communities in India. The Baghdadis, the Bene Israels and Cochinis. The Baghdadi Jews were much strict about religious laws than the Bene Israel Jews. The Baghdadis did not mingle with Bene Israel Jews. The Baghdadis did not allow marriages between their children and the children of Bene Israel. They did not eat food prepared by Bene Israel and they refused to count the Bene Israel as part of the Minyan (the ten necessary to start a Jewish prayer). Many explain these relations as an influence of the Indian caste system on the Jewish communities. According to this explanation, the Baghdadi Jews referred to themselves as higher caste than the Bene Israel Jews and therefore did not mingle with them. But these relations between the Jewish communities can also be explained according to the Jewish Halacha laws. The Baghdadi Jews who were much strict about Jewish laws and diet did not mingle with the Bene Israels because the Bene Israels were secular Jews and they perceived in Bene Israel Jews as impure Jews.
The Muslims who arrived in India were strong and powerful to be treated as untouchables. Not only were they strong in the military sense, they also tried to enforce their religion on the Indians. The Indians who converted to Islam in most of the cases remained in the same social status as they had before their conversion to Islam. Hindus from the higher Varnas remained at the higher levels of Indian society. Hindus from the lower levels of the hierarchy thought that by converting to Islam they would come out from the Hindu hierarchy system, but in most of the cases they remained in the same hierarchy level after they converted. Among the Muslims of India there has developed a two-tier hierarchy. The upper class, called Sharif Jat, includes Muslims who belonged to the higher levels in caste hierarchy and also Muslims who arrived to India from foreign countries. The lower class, called Ajlaf Jat, includes Muslim converts from lower castes. As in the world, the upper classes do not have close social relations with lower classes, the same way the Sharif Jat do not normally have close social relations with Ajlaf Jat.
The different Christian communities of India were treated in different ways in different parts of India. The Syrian Christians of Kerala had a high status. Along with the Jews, they were the business communities of Kerala and they too had aristocratic rights. The Indians who were baptized from the 16th century by Christian missionaries remained mostly in the same status they had before. As in the Muslim community of India, the Christians also have a two-tier social hierarchy. Many untouchables who converted to Christianity are still treated as untouchables, sometimes by other Christians.
The European Christians are also supposed to be untouchables to Hindus. Some Europeans in the 17th and 18th century even claimed that they were treated as untouchables. But later on with British rule over India it were the upper level Hindu castes, specially the Brahmans, who adopted the European democratic philosophy according to which all are equal and they introduced it to other Indians.
Other religions which were established in India - Buddhism, Jainism and Sikhism - also have some marks of caste system, even though they oppose caste system. Sikhism rejects caste system. But different Jats who adopted Sikhism act according to traditional Jat lines. The different Jats normally marry within caste lines. The Jats which were the elite of the Punjab and converted to Sikhism do not give equal respect to Sikhs who belong to the lower levels of Indian hierarchy. The Jains also have separate communities who marry within the community lines. The Buddhist in India have a two-tier hierarchy and just like in the cases of Christians and Muslims it is also related to the status of the community to whom the person belongs. On the other hand the Mahar community of west India, who were untouchables and converted mostly to Buddhism, prefer, because of different political reasons to recognize themselves as Mahars and not always as Buddhists.
Not all residents of India were part of the caste system. About 7% of India's population are referred to as tribes and not as castes or Jats. These tribes are scattered all around India and they are descendants of communities who were not interested in the Varna hierarchy. They preferred to live away from the main societies deep in the jungles, forests and mountains of India. They survived mostly on fishing, hunting or simple agriculture, and also from stealing, robbing and plundering. These tribes had different religious beliefs and different gods. Some of them had simple beliefs, but others use to sacrifice human beings in their ceremonies. One such tribe, called Gond, had a strong kingdom in central India. Most of the tribes adopted Hinduism, others adopted Islam or Christianity. Some tribes in East India claim to Jewish origin.
