The Pakistani caste system has developed along lines similar to those in India. Syeds (also known as Shahs in Sindh) claim to be the descendants of the prophet Muhammad (SAW) and are the highest caste in most places. In Punjab, the Ranas (Rajpoots), Chaudhurys and Maliks are considered higher caste, whereas the Kammis (workers), Chuhras (“untouchable” sweepers who are mostly Christian), Mussali (Muslim shaikh - menial workers) and Miraasi (musicians) are considered lower caste. In the NWFP, “lower castes” are referred to as Neech Zaat (low caste) and Badnasal (of bad lineage). In Balochistan the “lower castes” include Ghulams (slaves), Lohris (musicians), and Lachhis (Dalits). In Sindh, “high-caste” Muslims, in addition to Shahs and Syeds, include the Akhunds, Effendis, Soomros, Talpurs, and Pirs. Hajjams (barbers), Dhobis (washers), Kumbhars (potters), Maachis/ Mallahs (fisherfolk) and Bhajeer (Dalit converts to Islam) are considered “low caste”. In places like Swat, the Quom system is comparative to the Hindu caste system. Here, groups are divided rigidly according to occupation. Quoms do not intermarry or live together. The fact that caste is an important social identity for Pakistani Muslims is reinforced in matchmaking/ marriage services, where caste is one of the key attributes mentioned by prospective brides and grooms. Caste based marriage preferences and associations are documented amongst Pakistanis in the Diaspora, especially in the UK.
