Dalmatia was a Roman province. Its name is derived from the name of an Illyrian tribe called the Dalmatae, which lived in the central area of the eastern coast of the Adriatic Sea. It encompassed the northern part of present-day Albania, much of Croatia, Bosnia and Herzegovina, Montenegro, and Serbia, thus covering an area significantly larger than the current Croatian and Montenegrin region of Dalmatia. Originally this region was called Illyria or Illyricum.
