Philadelphia and Laodicea
Philadelphia ( Revelation 3:7-13 ): The city of Philadelphia lay fifty kilometers southeast of Sardis and between it and Laodicea. It straddled a major road into the interior; trade with other regions was vital to its economic life. Philadelphia was established as a city around in 189 B.C. by Eumenés II, king of Pergamos. He named it in honor of his brother and successor, Attalus II . The city came under Roman rule when the last king, Attalus III, bequeathed Pergamos to Rome in his will (133 B.C.).
