The Illyrians produce and trade cattle, horses, agricultural goods, and wares fashioned from locally mined copper and iron.

Feuds and warfare are constant facts of life for the Illyrian tribes, and Illyrian pirates plague shipping on the Adriatic Sea.

Councils of elders choose the chieftains who head each of the numerous Illyrian tribes.

From time to time, local chieftains extend their rule over other tribes and form short-lived kingdoms.

During the fifth century BCE, a well-developed Illyrian population center exists as far north as the upper Sava River valley in what is now Slovenia.

Illyrian friezes discovered near the present-day Slovenian city of Ljubljana depict ritual sacrifices, feasts, battles, sporting events, and other activities.

…Emona (Ljubljana, Slovenia), together with the portion of the tribe of the Taurisci that lives near the source of the Sava River.

Emona or Aemona, short for Colonia Iulia (A)emona, is a Roman castrum founded in 14/15 CE, possibly by the XV Legio Apollinaris (theory proposed by the noted historian and epigraphy expert Balduin Saria), on a territory already populated by ancient settlers of uncertain origin.

Situated on the Ljubljanica River near its junction with the Sava, its location overlaps with the southwestern part of the old nucleus of the modern city of Ljubljana, capital of Slovenia, where numerous remains of Emona can still be seen today (substantial parts of the ancient city walls, several mosaics, parts of the paleochristian baptistry, residential houses, statues, tombstones etc.).

(A)emona is, along with Nauportus, Celeia and Poetovio, one of the main cities on the eastern coast of the Adriatic.

Formerly, it was assumed to have been a part of the Roman province of Pannonia.

However, recent research seems to indicate that Aemona was actually the easternmost city of the Roman empire proper.

The Huns, led by Attila in 452, virtually destroy the city of Emona. Its remaining inhabitants flee the city; some of them made it to the coast of Istria.
