Philippi was the first city of the Roman district called Macedonia Prima. It was made a Roman colony by Augustus in honor of his celebrated victory over Brutus and Cassius. As a colony it was considered an extension of Rome transplanted to the provinces. Its inhabitants were Roman citizens who had the privilege of voting and were governed by thier own Senate and legislature.
The epistle to the Philippians was written to the believers in this city which was the first place that the Word of God moved in Europe.
