Pakistani Punjabis
Punjabis make up almost 45% of the population of Pakistan. The Punjabis found in Pakistan belong to groups known as biradaris, which descend from a common male ancestor. In addition, Punjabi society is divided into two divisions, the zamindar groups or qoums, traditionally associated with farming and the moeens, who are traditionally artisans. Zamindars are further divided into qoups that claim pre-Islamic ancestry such as the Rajput,Aheers, Harals, Ghosi (tribe), Jat, Shaikhs or (Muslim Khatri), Kambohs, Gujjars, Dogars and Rahmani (Muslim Labana). Zamindar groups claiming Central Asian or Middle Eastern ancestry include the Gakhars, Khattar, Awan, Mughal and Arain, comprising the main tribes in the north of the province, while Khagga, Bodla, Jhandir, Daudpota, Gardezi, Syed and Quraishi are found in the south, all of whom claim Arab ancestry. Immigrants from neighbouring regions, such as the Kashmiri, Pashtun and Baluch ,also form important element in the Punjabi population. Pashtun tribes like the Niazis and the Khakwanis, are integrated into Punjabi village life. Especially the members of the Niazi tribe, who see themselves as Punjabis first. They have big communities in Mianwali, Bakkar, Lahore, Faisalabad, Sahiwal and Toba Tek Singh. Major Moeen groups include the Lohar, Khateek, Rawal, Chhimba Darzi, Teli, Julaha, Mallaah, Mirasi, who are associated with a particular crafts or occupation.[34]
Punjabis have traditionally and historically been farmers and soldiers, which has transferred into modern times with their dominance of agriculture and military fields in Pakistan. In addition, Punjabis in Pakistan have been quite prominent politically, having had many elected Members of Parliament. As the most ardent supporters of a Pakistani state, the Punjabis in Pakistan have shown a strong predilection towards the adoption of the Urdu language but nearly all speak Punjabi, and still identify themselves as ethnic Punjabis for the most part. Religious homogeneity remains elusive as a predominant Islamic Sunni-Shia population and a Christian minority have not completely wiped out diversity since the partition of British India. A variety of related sub-groups exist in Pakistan and are often considered by many Pakistani Punjabis to be simply regional Punjabis including the Seraikis (who overlap and are often considered transitional with the Sindhis) and Punjabi Pathans (which publications like Encyclopædia Britannica consider a transitional group between Punjabis and Pathans.
