Easton's 1897 Bible Dictionary:

Dalmatia
   a mountainous country on the eastern shore of the Adriatic, a
   part of the Roman province of Illyricum. It still bears its
   ancient name. During Paul's second imprisonment at Rome, Titus
   left him to visit Dalmatia (2 Tim. 4:10) for some unknown
   purpose. Paul had himself formerly preached in that region (Rom.
   15:19).

     The present Emperor of Austria bears, among his other titles,
   that of "King of Dalmatia."
