Dictionary Summary: A country to the north-west of Macedonia, on the eastern shores of the Adriatic, now almost wholly comprehended in Dalmatia, a name formerly given to the southern part of Illyricum ([2 Tim. 4:10](/2tim#2Tim.4.10)). It was traversed by Paul in his third missionary journey ([Rom. 15:19](/rom#Rom.15.19)). It was the farthest district he had reached in preaching the gospel of Christ. This reference to Illyricum is in harmony with [Acts 20:2](/acts#Acts.20.2), inasmuch as the apostle’s journey over the parts of Macedonia would bring him to the borders of Illyricum. ²
