The structure of Indian society is based on the caste system. At the apex of this system are the Brahmins, temple priests who are considered as the connection between people and the gods. They perform religious rites and rituals . Next are the Kshatriyas, the rulers and warriors. They are responsible for offering gifts and make sacrifices to gods via Brahmins to protect the people. After them comes the Vaishyas, the merchants and farmers. Below them are the Shudras, the unskilled labour classes. It is their duty to serve the three higher classes. At the lowest level of the system are the untouchables. They are viewd as unclean and perform the unclean tasks in society. They are alienated from the society, excluded from education, religious temples and so on.
