Tribes are just for an identity not more than that one would like to proud. Well I also from Abbasi Family, Alkhamdu Lillah its Allah's Blessing to give me such a noble and honored family. Abbasi Family belongs to Hazrat Abbas (Rz) the Beloved Uncle of Hazrat Muhammad(SAWW). Abbasi Ruled more than 550 Years.After the death of last Abbasi Khalifa Ameer Channi Khan has migerated Baghdad to Sindh. he has two sons 1. Daud Khan ( The Ancestor of Tribe "Daud Pota") 2. Mehdi Khan ( The Ancestor of "Kalhora" Tribe and Rulers of Sindh)
Some people were migerated during and before starting of Abbasi's Rule to all over the world. In 1472, Nawab Azeem Khan Taniwal has arrived from Darra Tannal, Ghazni, Afghanistan to Swat Pakistan. He has defeated areas of Swabi, Mardan, Trbella, Hazara. He Has two sons 1. Mir Paal Khan (The Ancestor of Pllal Khel Taniwal (Tanoli) 2. Mir Hind Khan Taniwal (Tanoli) The ancestor of Hinwal Taniwals (Tanolis)
You should clear one Thing in Tanawal, Hazara the Tribe Tanoli is a Sub-Tribe of Tribe Abbasi.
One more intresting thing Nawabs of Bhawalpur, Bhawal Nagar and Rahim Yar Khan were and are Abbasis and The Nawabs of State of Amb (Dar Band) Mansehra, Hazara were also Nawab of Tribe Tanoli (Abbasi) As Nawab Akram Khan, Paienda Khan, Suba Khan, Nawab Khan, Nawab Khani Zaman Khan, Nawab Saeed Khan, Nawabzada Sallah ud Din Saeed Khan (he has currently loose the election from the Plate from of PPP).
I thinj it is enough for you today to digest and spread to others.
But these things are just for information not for proud becoz Allah will never justice on the basis of Tribes only Deeds of a person will play the Role.
