Hinduism, but the caste system did not have it's origin in Hinduism, but was put in place in India, and still affects people in bad ways today.
Their belief in Reincarnation.
reincarnation moves you through the cast system
No this is simply not true. Thoughts of Reincarnation (punarjanma) & Caste System are completely different.
if you die you can have rebirth into a higher caste system
In a class, you can depending how well you do, improve from one class to another class. In the caste system, one is born in a caste, and cannot move to another caste, except by reincarnation
Various religions have influenced the caste system, but it is predominantly associated with Hinduism in India. The caste system is based on the belief in karma and reincarnation, where individuals are born into a particular caste based on their past actions. Hindu scriptures, such as the Manusmriti, have historically supported and enforced this hierarchical social structure.
(This has been remade and made better, original answer: it has to do with the gov't. spred the love -Sassycat000126)Karma and the Caste system are related because Karma means a good life and which that relates to Reincarnation because the higher Karma you have, the more of the chance you will live again from Reincarnation,an answer for how does Reincarnation and the Caste system relate: The same between the Caste System and reincarnation is when a person is born in a certain caste. The person cannot become a member of another caste. But some say that if that person was good, responsible and well-mannered, He or she could reincarnate (which means to be born again) and be born in a higher class, with a better life.Post remade by William
