While Pashtuns dominated the country since they constitute the majority of the Afghan population, Persian culture still permeated. In the early history of Afghanistan as an independent country, many Pashtuns moved into urbanized areas and adopted Dari as their language. As a result, many ethnic Pashtuns in Afghanistan identify themselves as Tajiks[citation needed] but still have Pashtun names (such as a last name with the suffix "-zai") simply because they speak Dari and are assimilated into Tajiki culture in the country within a process known as "de-tribalization".
