Endogamy is the cultural practice of only marrying within a specific social group, religious denomination, caste, or ethnic group, rejecting any from outside of the group or belief structure as unsuitable for marriage or other close personal relationships. Its opposite, exogamy, describes the social norm of marriage outside of the group.

Untouchability is a form of social institution that legitimises and enforces practices that are discriminatory, humiliating, exclusionary and exploitative against people belonging to certain social groups. Untouchability also refers to the condition of belonging to such groups, members of whom are historically called untouchables, outcastes, or archaically pariahs. Although comparable forms of discrimination are found all over the world, untouchability involving the caste system is largely unique to South Asia.

Neo-feudalism or new feudalism is a theorized contemporary rebirth of policies of governance, economy, and public life, reminiscent of those which were present in many feudal societies. Such aspects include, but are not limited to: Unequal rights and legal protections for common people and for nobility, dominance of societies by a small and powerful elite, a lack of social mobility, and relations of lordship and serfdom between the elite and the people, where the former are rich and the latter poor.
