<human>:  Why are they called Dalits?
<bot>: The word Dalit is derived from the Sanskrit word D<unk>lak<unk>, which means “untouchable”. In ancient India, people were divided into four social classes: Brahmins, Kshatriyas, Vaishyas, and Shudras. The lowest class was the Shudras, who were considered to be “untouchable” and could not enter temples or perform other religious rituals. They were also forbidden from eating at the same table as higher caste people. The Dalits were the lowest caste, and they were not allowed to marry into the higher castes.
