Colony
Easton’s Bible Dictionary
Colony: The city of Philippi was a Roman colony (Acts 16:12), i.e., a military settlement of Roman soldiers and citizens, planted there to keep in subjection a newly-conquered district. A colony was Rome in miniature, under Roman municipal law, but governed by military officers (praetors and lictors), not by proconsuls. It had an independent internal government, the jus Italicum; i.e., the privileges of Italian citizens.
