The name "Kakazai" means "descendants/offspring/children of Kaka (? / )" (in Pashto, Kaka literally means Uncle and used to address an elderly person as well as Paternal Uncle whereas Kakae = a contemporary but obsolete Afghan name for a male.Zai (Pashto: , Urdu, Persian: ?) = descendants/offspring/children of, a root also used in other Pashtun tribes such as Yousafzai). Given that Mamund, the father of Kakazai, had two sons: Kakazai and Wur or Wara (Urdu: / , Pashto: ), meaning small, little or minor, also known as Wur Mamund or Wara Mamund (Urdu: / ? ? , Pashto: ? / ?), meaning small, little or minor Mamund or descendants/offspring/children of small, little, minor Mamund, thus, in this particular case Kakazai means descendants/offspring/children of the elder person/brother hence also known as Loi Mamund (Pashto: ; Urdu: ? / ? ?), meaning great, large, huge, big Mamund or descendants/offspring/children of great, large, huge, big Mamund. Spelling variants include: Kakizi, Kakaezai, Kakezai, Kakaizai, Kakay Zai, Kakayzai, Kakeyzai, Kaka Zai and Kakkayzai.
Noting the martial legacy of the Kakazai Pashtuns, Pir Moazzam Shah in his book 'Tawareekh-e-Hafiz Rahmat Khani' (Page 89-91 - Originally Published in 1624 AD) and Olaf Caroe in his book 'The Pathans 550 BC-AD 1957' (Page 184-185 - First published in 1958), wrote about a battle between the Yousafzais and the Dilazaks in which Malik Haibu (Dilazak) was given the first sword blow by Payenda Kakazai Tarklanri but eventually got beheaded by Burhan Kakazai Tarklanri sword blow while fighting on the side of the Yousafzais in order to aid them to conquer Bajour from the Dilazaks.
For the invading armies, much of Punjab and other areas became a repository with rest houses, cantonments and border posts established to keep an eye on things in the region as well as to keep abreast of any new information (such as the possible weakening of another empire etc.), and many officers along with their families would settle there. As is still very true in large areas of Khyber Pakhtunkhwa and Afghanistan's Pashtun belt, the land is often quite barren and hostile only capable of hosting a limited population. Once the population or a tribe's numbers exceeded a certain threshold, they would often travel East to more settled areas (Sindh, Punjab, Kashmir etc.) or would be pushed out by other tribes in the search of productive agricultural land. The area of Sialkot principally, as well as Faisalabad, Wazirabad and parts of Lahore, had much productive agricultural lands and were ruled by a series of Pashtun families many of whom were Kakazai but also Burki and NiaziPashtuns.
