Note 1 at Acts 16:9: Macedonia was the country just north of Achaia (see note ? at Acts 18:12). It occupied the northern part of what we know today as Greece.

It's principal cities were Neapolis (see note ? at Acts 16:11, p. ???), Philippi (see note ? at Acts 16:12, p. ???), Amphipolis (see note ? at Acts 17:1, p. ???), Apollonia (see note ? at Acts 17:1 p. ???), Thessalonica (see note ? at Acts 17:1, p. ???), and Berea (see note ? at Acts 17:10).

The first importance of the country of Macedon came in 359 B.C. when Philip of Macedon began to expand it's borders through conquest. His son, Alexander the Great (336-323 B.C.), brought Macedon, or Greece, to be a world-wide power that was prophesied in Dan. 8:5, 8, 21-23.

Paul brought the gospel to Macedonia on his second missionary journey (Acts 15:40-19:22) and also passed through this area at least twice on his third missionary trip (Acts 20:1, 3). Gaius, Aristarchus, Sopater, and Secundus, Paul's companions, were Macedonians (Acts 19:29; 20:4).
