A dera is a type of socio-religious organization in northern India. Jacob Copeman defines the deras as "monasteries or the extended residential sites of religious leaders; frequently just glossed as sect". Several deras started out as non-orthodox Sikh sects, and many of them are now centres of distinct non-Sikh religious movements. Many Deras have attracted a large number of outcast Dalits, who earlier embraced Sikhism to escape the Hindu casteism, but felt socially excluded by the Jat Sikh-dominated clerical establishment.
