If a Hindu person were asked to explain the nature of the caste system, he or she might start to tell the story of Brahma — the four-headed, four-handed deity worshipped as the creator of the universe.
What does "Caste" Mean?
Even today, most Indian languages use the term "jati" for the system of hereditary social structures in South Asia. When Portuguese travelers to 16th-century India first encountered what appeared to them to be race-based social stratification, they used the Portuguese term "casta" — which means "race" — to describe what they saw. Today, the term "caste" is used to describe stratified societies based on hereditary groups not only in South Asia but throughout the world.
A caste system is a class structure that is determined by birth. Loosely, it means that in some societies, if your parents are poor, you're going to be poor, too.
Caste-based difference have also been practicing in other regions and religions in the indian subcontinent like Nepalese Buddhism,Christanity,Islam,Juddism and Sikhism.
