The ethnonym Afghan has been used historically to refer to the Pashtuns. Since the second half of the twentieth century, the term "Afghan" evolved into a demonym for all residents of Afghanistan, including those outside of the Pashtun ethnicity.

Pashtuns, also known as Pakhtuns, or Pathans, are a nomadic, pastoral, Eastern Iranic ethnic group primarily residing in northwestern Pakistan and southern and eastern Afghanistan. They historically were also referred to as Afghans until the ratification of the 1964 Constitution of Afghanistan, which stated anyone with citizenship is Afghan, and the 1970s after the term's meaning had become a demonym for members of all ethnic groups in Afghanistan.
