 The name "Dalmatia" was in use probably from the second half of the 2nd century BC and certainly from the first half of the 1st century BC, defining a coastal area of the eastern Adriatic between the Krka and Neretva rivers.It was slowly incorporated into Roman possessions until the Roman province of Illyricum was formally established around 32–27 BC.In 9 AD the Dalmatians raised the last in a series of revolts together with the Pannonians, but it was finally crushed and, in 10 AD, Illyricum was split into two provinces, Pannonia and Dalmatia, which spread into larger area inland to cover all of the Dinaric Alps and most of the eastern Adriatic coast.
