Karzai is believed to be from the Shamizai subtribe of the Popalzais. His grandfather, Khair Muhammad Karzai, was a head of the Popalzai tribe from Kandahar who relocated to Kabul and ran the business of a guest house. This allowed Karzai's father Abdul Ahad, to gain a foothold in the royal family, and subsequently, the parliament. These actions and upwards movement within the Popalzai tribal system, led to the Karzai family furnishing a viable Shamizai clan alternative to Sadozai leadership in the aftermath of the Soviet invasion when the Sadozai clan failed to provide a tribal leader. He is often seen wearing a Karakul hat, something that has been worn by many Afghan kings in the past.
