On the other hand there were many Brahmans who were landlords and businessmen, professions supposed to belong to the Vaisia Varna. Also among the other Varnas not all professed the occupations worthy of their Varna. In west India the Maratha were the warriors and the aristocracy. Originally the Marathas belonged to the different Jats in west India. Most of these Jats were in Sudra level. But the Marathas who became the aristocracy of west India claimed and acquired the Kshatria status.
In the 17th and the 18th century the Marathas even established an empire which ruled large parts of India. During the Maratha reign members of a Brahman Jat, Konkanash Brahman, were ministers. From 1750 these Brahmans became the rulers of the Maratha Empire. Like the Marathas there were other communities which, religiously did not belong to the Kshatria status but acquired this status. The Reddy in Andra Pradesh and Nayar in Kerala are such two examples.
Religiously marriage occurs within the Jat . The different Jats members almost always respected this rule and people who dared break this rule were outcasted. But this rule also had exceptions. Usually the higher Varnas were very strict about this custom. But in some of the higher level Jats of the society, they used to have polygamy. In these cases, because of scarcity of women, men use to marry women from the lower levels of the society.
In some Indian societies between-jat marriage was even an acceptable feature. One such example of marriages existed in Kerala, in south India. In Kerala, Nayar women (aristocracy community) married men from Numbodiri Brahman community. Another problem considering the Jat marriage was the internal structure of the Jats. As stated earlier some Jats break up into smaller communities.
In most of the cases each such community members marry only with members of their own community and not with other community members within the Jat. In some cases there is a hierarchy between the different communities of the same Jat. In such cases a daughter from the lower community could marry a son from the higher community but not vice versa. Each Varna had different diet . Hinduism has many strict dietary rules.
In general the higher Jats are more strict about their dietary customs than the lower Jats. The Brahman Jats have the most strict dietary customs. They will not eat in lower Jats homes or even with lower Jats (because of this reason many restaurants hired Brahman cooks).
