Dilazak (Pashto: دیلازک) is a Pashtun tribe from the Karlani confederation of Pashtuns.
History
The Dilazak Pashtuns are believed to have first settled the regions across the Khyber Pass in the 11th century, from the areas of Bajaur to the Peshawar Valley with Sultan Mahmud of Ghazni, and a large contingent of Dilazaks joined Sultan Mahmud for his expedition against Somnath.Ḥayāt-i Afghānī (1867) by Muhammad Hayat KhanThe Pathans: 550 B.C.—A.D. 1957 by Olaf Caroe pg. 175
The natives were written to be red-complexioned "kafirs" and were displaced or left due to subjection by the Dilazaks, who after conquering the region drove out the natives away into the mountain retreats of the neighbouring valleys.The Races of Afghanistan by Henry Walter Bellew pg. 66
Around 1520, another Pashtun tribe, the Yousafzai, was expelled from Kabul by Mirza Ulugh Beg, a Timurid."The Pathans" by Sir Olaf Caroe Page 153,173/174 The Yusufzai migrated to Peshawar Valley where they sought and received help from the Dilazaks."Mukhtasur Taareekh-e-Pashtoon (Short History of Pashtoons) by Professor Hameedullah (2004) Page 49 Later, the relationships between the two tribes deteriorated and a long war ensued."Tawareekh-e-Hafiz Rahmat Khani" (Urdu) by Pir Moazzam Shah rearranged with notes by 'Roshan Khan', Published by Pashto Academy, Peshawar University (1976) Pages 83-570 20 years later, at the battle of Katlang, the Yousafzai and Allied forces pushed the Dilazak east of the Indus River under the leadership of Malik Ahmad Khan."The Kingdom of Afghanistan - A Historical Sketch" by G.P.Tate (1911), Reproduced by 'Indus Publications' (1973) Page 12 (Foot Note)
