Jerash, considered one of the most important and best preserved Roman cities in the Middle East, is the site of the ruins of the Greco-Roman city of Gerasa. Excavations show that Jerash was inhabited during the Bronze Age, 3200 BC - 1200 BC. In AD 90, Jerash was absorbed into the Roman province of Arabia, which included the city of Philadelphia, modern day Amman. The Persian invasion in AD 614 caused the rapid decline of Jerash, but the city continued to flourish during the Umayyad Period. Large parts of Jerash was destroyed by a strong earthquake in 749 AD, while subsequent earthquakes and wars contributed to additional destruction.
