There are four castes in Hindu religion arranged in a hierarchy. The highest caste is Brahman, and they are the priest caste of Hinduism. After them are the Kshatria, who are the warrior castes. After them are the Vaishya caste , who are business people.
The caste system in India is an important part of ancient Hindu tradition and dates back to 1200 BCE. The term caste was first used by Portuguese travelers who came to India in the 16th century. Caste comes from the Spanish and Portuguese word casta which means race, breed, or lineage. Many Indians use the term jati.
