This paper deals with the existence of the Illyrian people Ardiaei from their first appearance in the classical sources to their defeat by Rome and their migration into the interior when they disappeared from the historical scene. The paper tries to determine the geographical position of the Ardiaei in different periods according to both the ancient sources and their modern interpretations. The paper presents both the major problems relating to the geographical location of the Ardiaei, such as the position of the "great lake" and "salt springs", which are found in classical sources and the opposing views of modern authors, which come from different interpretations of those sources. A part of the content deals with an important Adriaeian economic branch, piracy, because of which the classical sources often referred to them and for which they were attacked by Rome. The Ardiaei were in their full strength just before the First Illyrian War, during the reign of Agron and Teuta whose, conquests and the defeat in the above-mentioned war, are also some of the most important topics in the work. At the very end there is a modern interpretation of Polybius, who spoke about Teuta as a temerity and irrational woman, where the author attempted to show what was the Greek view on women like.
