 They were led by Bato the Daesitiate, a chieftain of the Daesitiatae in the central part of present-day Bosnia, and were later joined by the Breuci, a tribe in Pannonia led by Bato the Breucian.Many other tribes in Illyria also joined the revolt.The Romans referred to the conflict as "Bellum Batonianum" ("Batonian War") after these two leaders with the same name; Velleius Paterculus called it the Pannonian and Dalmatian War because it involved both regions of Illyricum, and in English it has also been called the Great Illyrian Revolt, Pannonian–Dalmatian uprising, and Bato uprising.
