The Ardiaei were an Illyrian people who resided in the territory of present-day Bosnia and Herzegovina, Albania, Kosovo, Montenegro, and Croatia between the Adriatic coast on the south, Konjic on the north, along the Neretva river and its right bank on the west, and extending to Lake Shkodra to the southeast. From the 3rd century BC to 168 BC the capital cities of the Ardiaean State were Rhizon and Scodra.
The Ardiaean kingdom was transformed into a formidable power—both on land and sea—under the leadership of Agron of Illyria. During this time, Agron captured parts of Epirus, Corcyra, Epidamnos, and Pharos in succession, establishing garrisons there. The Ardiaean realm became one of Rome's major enemies, and the primary threat to it in the Adriatic Sea. A series of wars were fought between the Roman Republic and the Illyrian (Ardiaean-Labaeatan) kingdom in the 3rd–2nd centuries BC. Polybius (203 BC–120 BC) wrote that they were subdued by the Romans in 229 BC. The Epitome of Livy reports the Roman consul Fulvius Flaccus put down an uprising in 135 BC undertaken by Ardiaei and Pleraei in Roman Illyria.
