The term Caste hierarchy means the social division of people in different groups in society. According to the Hindu religion, there are four caste - Brahmin, Kshatriya, Vaishya, and Shudra. In this caste hierarchy, Brahmins are placed at the top and Shudras are placed at the bottom. Earlier this caste hierarchy was based on occupation but now it is based on birth. It means, if someone is Brahmin then his children will be Brahmin automatically.
