When Augustus became emperor in 27
BC, he made Ephesus instead of Pergamon the capital of proconsular Asia, which covered the western part of Asia Minor. Ephesus entered an era of prosperity. It became the seat of the governor, growing into a metropolis and a major center of commerce. It was second in importance and size only to Rome. Ephesus has been estimated to be in the range of 400,000 to 500,000 inhabitants in the year 100, making it the largest city in Roman Asia and of the day. Ephesus was at its peak during the first and second century AD.
The city was famed for the Temple of Artemis (Diana), who had her chief shrine there, the Library of Celsus, and its theatre, which was capable of holding 25,000 spectators. This
open-air theater was used initially for drama, but during later Roman times gladiatorial combats were also held on its stage, with the first archaeological evidence of a gladiator graveyard found in May 2007. The population of Ephesus also had several major bath complexes, built at various points while the city was under Roman rule. The city had one of the most advanced aqueduct systems in the ancient world, with multiple aqueducts of various sizes to supply different areas of the city, including 4 major aqueducts.
.The city and the temple were destroyed by the Goths in 263. This marked the decline of the splendor of the city.
