Mr Abir...i had a huge debate on the issue of ethinicity of people of Pakistani Punjab with a indian dude on this forum this morning..u can check it..here is my part which will explain u why other than gujjars, jutts, rajputs and araees which are in considerable amount...other than these there are people of diverese ethinic backgrounds in Pakistan's Punjab who fluently speak Punjabi....Indian Punjabis are natives while most of ppl on Pakistan's Punjab side arn't dendents of natives...here is why
The group which indians claim is associated with them is punjabis.
Let's examine this province of punjab.
-you have millions of people in punjab from families of Sayyed, Qureshi, shah, Salara, Awans, the Khagga, the Dhund Abbasi, the Dhanyal, the Hans, the Hashmi (Nekokara), the Kahut and the Bodla,Thaheem ...their ancestors started comming to south punjab once it was part of ummayad caliphate and later abbasid caliphate....Muhammad Bin Qasim himself came up to Multan with 20000 Syrian Cavilary...and all of these have family histories dating back to arrival of arabs during rule of ummayads and abbasids.
- The families whose ancestors converted to islam include jatts, rajputs , araees and few other muhajir families and they are in large numbers but not in majority as our indian friends claim.
-There were mass migrations from muslim areas of central asia and persia to muslim ruled indian subcontinent due to Mongol invasions...and from Karachi to Punjab..people with their decent could be found ranging from sindh to northern pakistan and even in kashmir......
- In Punjab tribes who claim to come from afghanistan are gardezis (from gardez) a shia tribe in south punjab, sadozai ( again from Tarnak, Kandahar, and Kabul and are decendants of ahmed shah abdali) are spread out from peshawar to lahore and kashmir with some decedants even in present day india.
- Northern Punjab...u have people like niazis (pushtun tribe but mainly in mianwali, with significant niazi diaspora in lahor, karachi, islamabad , chakwal, parts of afghanistan)...some also call these ppl "punjabi pathans" espeacialy those in punjab...some famous niazis include imran khan a famous politician.
Hence in Pakistan's Punjab unlike Indian Punjab.....there are people from diverse ethinic backgrounds...including the local indian background...but they arnt in majority as u claim...dont forget more than 4-5 million natives of Punjab..migrated from Pakistan's Punjab to India
