The first uncontested mention of the city is from the 5th century BC in the work of
Hellanicus of Lesbos. The first famous event connected with the city is in 190 BC, when
Antiochus the Great was defeated in the
battle of Magnesia by the
Roman consul Lucius Cornelius Scipio Asiaticus. It became a city of importance under Roman rule and, though nearly
destroyed by an earthquake in the reign of
Tiberius, was restored with financial help from that emperor and flourished through the Roman Empire. It was an important regional centre through the
Byzantine Empire, and during the 13th-century interregnum of the
Empire of Nicea. Magnesia housed the Imperial mint, the Imperial treasury, and served as the functional capital of the Empire until the recovery of
Constantinople in 1261. The city prospered under the
Laskaris and its warehouses and depots received goods from as far as Egypt and India through the
Italian city-states. In the late 13th and early 14th centuries the region of Magnesia was subject to repeated raids by invading Turkish bands. After a failed campaign in 1302 by then co-emperor
Michael IX and his unsuccessful defence of the city, most inhabitants fled to the Aegean coast and the European part of the Byzantine Empire. At least 100 refugees were killed by the Turks on their way to neighbouring
Pergamon. As a result of the Turkish invasion of the region, and the destruction of the city, the area became largely desolate. == Landmarks ==
