1911 Encyclopædia Britannica/Aimak
AIMAK, or Eimak (Mongolian for “clan,” or section of a tribe), the name given to certain nomadic or semi-nomadic tribes of Mongolian stock inhabiting the north and north-west Afghan highlands immediately to the north of Herat. They were originally known as “chahar (the four) Eimaks,” because there were four principal tribes: the Taimani (the predominating element in the population of Ghur), the Ferozkhoi, the Iamshidi and, according to some authorities, the Hazara. The Aimak peoples number upwards of a quarter of a million, and speak a dialect said to be closely related to the Kalrnuck. They are Sunnite Mahommedans in distinction from the Hazara who are Shiites. They are predominantly of Iranian or quasi-Iranian blood, while the Hazara are Turanian. They are a bold, wild people and renowned fighters.
