Mazaei or Maezaei (Ancient Greek: Μαζαῖοι/Μαιζαῖοι) were a sub-tribe of the Illyrians, autochthonous to the interior of today's Bosnia and Herzegovina, settled mainly in the Sana river basin, the middle course of Vrbas, and around the Vrbanja and Ugar rivers.
[2] They settled in the Sana river basin, the middle course of Vrbas, and around the Vrbanja and Ugar rivers, and were bordered on the east by the Dardans[citation needed], on the west by Iapodes, the Una river, Krka waterfalls, and Iasis, on the north by Sava – Drava – Danube, and on the south by Liburni, Delmatae, and Breuci on the north-east.
Like other Illyrians, Mazaei lived in fortified or semi-fortified settlements, subsisting on agriculture, hunting and fishing, and craftsmanship.
Ancient writers like Herodian, Livy, Pliny, Strabo, Theophrastus and others described the Illyrians as tall, strong warriors, and heavy drinkers.
The term Illyria remained in use in Late Latin and throughout the medieval period.
