The Roman province of Asia comprised generally the southwest portion of Anatolia. Its first capital was Pergamum, but the capital was later changed to Ephesus. Asia residents were in Jerusalem at Pentecost (Acts 2:9 ). Paul the apostle traveled and preached extensively in Asia (Acts 19:10 ,Acts 19:10,19:22 ) especially in the neighborhood of Ephesus; but God forbade him to preach there prior to his Macedonian call (Acts 16:6 ). Men of Asia led to Paul's arrest in Jerusalem (Acts 21:27 ). 1Peter was addressed to Christians in Asia. Asia was the location of the seven churches to whom the Book of Revelation was addressed. Asia was known for its worship of Artemis (Acts 19:27 ). See Rome; Roman Empire.
