The Jireček Line is a conceptual boundary through the ancient Balkans that divides the influence of the Latin (in the north) and Greek (in the south) languages in the Roman Empire from antiquity until the 4th century. The border has been repeatedly corrected by the discovery of new inscriptions. A possible rough outline of it goes from near Lissus (near Lezhë and Laç in modern Albania) to Serdica (now Sofia, in Bulgaria) and then follows the Balkan Mountains to Odessus (Varna) on the Black Sea or continuing along the coastline northwards to the Danube Delta.
This line is important in establishing the area where the Romanian, Aromanian, Megleno-Romanian and Albanian people formed (see Origin of the Romanians and Origin of the Albanians). It was originally used by Czech historian Konstantin Jireček in 1911 in a history of the Slavic people.
The placement of the line is based on archaeological findings. Most of the inscriptions found to the north of it are written in Latin, and most of the inscriptions found to the south of it are in Greek.
The proposed line, in its various forms, is a theoretical tool. Already in antiquity there were significant exceptions: there were Hellenized groups north of the line (e.g. the Greek colonies along the western coastline of the Black Sea) and Latinized groups may have lived south of the line. Even so, it is a useful — although approximate — instrument for determining which influence a certain area was predominantly exposed to.
More recent scholars have revised it somewhat: Kaimio (1979) places Dalmatia and Moesia Superior in the Latin area and Moesia Inferior in the Greek sphere. MacLeod (1982) suggests that there may not have been "an official language policy for each and every aspect of life", but that "individual Roman officials [made] common sense ad hoc decisions". He also points out that while the area was under pre-Byzantine Roman rule, "even in Greek areas... Latin was the dominant language in inscriptions recording public works, on milestones, and in the army".
