Caste is a system of social status and hierarchy characterized not only by social rankings, wealth, and prestige, but also by hereditary occupations and endogamy. Well-behaved and properly brought-up members of a caste are supposed to marry within that caste, or occasionally with members of similarly situated castes.
Legally-entrenched social classes, also endogamous and hereditary, have been found in Europe, while anthropologists associate the paradigmatic ethnographic caste-system with Indian subcontinent (India, Pakistan, Nepal, Sri Lanka), where it is typically known as Jāti, from the Sanskrit for "birth" (जाति). Similar social structures have existed in a number of societies, however, including Edo-era Japan and various places in Latin America. The word caste, from the Spanish and Portuguese casta ("lineage" or "breed"), originated in Latin America. Latin Americans constructed elaborate classifications based on individuals' degree of European, African, and Native American "blood".
In the Indian subcontinent
The caste system is based on a theological concept called varna, again from the Sanskrit for "color" or "form" (वर्ण). Varna divides Hindu society and the many subgroupings of caste into four broad categories:
- the Brahmins: priests, teachers and preachers.
- the Kshatriyas: rulers and warriors.
- the Vaishyas: agriculturists, herdsmen, merchants, and artisans.
- the Shudras: laborers.
In the Hindu theology of reincarnation, the first three varnas are held to have been "twice born", meaning that those born into those groups must have spiritually progressed in their prior incarnations as human beings. Only members of the first three varnas are permitted to study the Vedas.
These varnas were organized into castes during the British rule of India the castes become much more elaborate than this fourfold theological division, and include multiple subgroupings (jāti) that vary from one region to another.
Untouchable and defiling castes
In many places it is considered defiling for members of the higher castes to have any dealings or conversation with certain low caste people. These people have occupations that are locally considered unclean but necessary, such as burying the dead or butchering animals. Such group of the "untouchable" is collectively called dalits in India. They suffer from untouchability; it is defiling for a member of a non-untouchable caste:
- to be touched by a Dalit,
- to touch an object previously touched by a Dalit,
- to touch a Dalit's shoes or clothing,
- to eat with a Dalit,
- to enter the home of a Dalit, or
- for a Dalit to enter the home of non-untouchable.
A statute in India seeks to redress social problems caused by discrimination against Dalits, but enforcement has been only sporadic and discrimination within the legal system continues to exist. The Hindu caste system is nevertheless slowly succumbing to social change due to transportation and capitalism. Marriages outside the caste have increased, especially since the 1970s, a process which blurs the lineages upon which caste itself is founded. However, while marriages among different jati have increased, marriages outside the four varna remain relatively less common.
Similar untouchable or outcast groups have existed elsewhere, including:
- The Burakumin of Japan;
- The Cagots of southern France and northern Spain
- The Al-Akhdam of Yemen
- The Roma or Gypsy people, especially in Eastern Europe.
In Latin America
A comparably elaborate system of racial classification existed in Latin America. The Spanish and Portuguese colonists of the New World brought with them a pre-existing notion of limpieza de sangre, 'purity of blood', which they had already developed as a result of the Reconquista, the reconquest of the Iberian Peninsula from the Islamic Moors of Grenada and Andalusia.
The concept of limpieza de sangre originally involved favoring purely European and Christian ancestry over descendants of African Moors and other disfavored groups including Jews. After the last Muslim state fell to Ferdinand and Isabella in 1492, the remaining Jews and Muslims were given the ultimatum to convert to Catholicism, leave, or die. Those who chose conversion faced abiding discrimination in Spanish society and their ancestors were often believed to practice Judaism or Islam in secret.
The Latin American system, though it gave English the word caste, is not a true caste system, lacking the critical component of endogamy, marriage within the caste. Indeed, the system recognizes the inevitability of miscegenation, and is based on classifying people according to their numbers of European, African, and Native American ancestors.
Other regions of the world
A similar system of describing people by the proportion of their European and African ancestry was also in play in much of the Caribbean and parts of the U.S. South, giving rise to racialized identities such as "quadroon" and "octoroon."
