In 89 BC, Mithridates VI Eupator, king of Pontus, seized the Roman Province of Asia (in western Anatolia). Mithridates then sent Archelaus (his leading military commander) to Greece, where he established Aristion as a tyrant in Athens.The Roman consul Lucius Cornelius Sulla landed in Epirus (in western Greece) and marched on Athens. He marched through Boeotia on his way to Attica. Sulla besieged Athens and Piraeus in 87-86 BC and then sacked Athens and destroyed Piraeus. He then defeated Archelaus at the Battle of Chaeronea and the Battle of Orchomenus, both fought in Boeotia in 86 BC. Roman rule was preserved. The commerce of Achaea was no longer a rival to that of Rome. After the defeat of Antony and Cleopatra, about 31 BC, the Emperor Augustus separated Macedonia from Achaea, though it remained a Senatorial province, as under the Republic. In AD 15, Emperor Tiberius, responding to complaints of mismanagement by the Senatorial proconsul made Achaea and Macedonia Imperial provinces. They were restored to the Senate as part of Emperor Claudius' reforms in AD 44. Over time, Greece would slowly rebuild, culminating during the reign of the Hellenophile Emperor Hadrian (117-138). Along with the Greek scholar Herodes Atticus, Hadrian undertook an extensive rebuilding program. He beautified Athens and many of the Greek cities. Copper, lead, and silver mines were exploited in Achaea, though production was not as great as the mines of other Roman-controlled areas, such as Noricum, Britannia, and the provinces of Hispania. Marble from Greek quarries was a valuable commodity. Educated Greek slaves were much in demand in Rome in the role of doctors and teachers, and educated men were a significant export. Achaea also produced household luxuries, such as furniture, pottery, cosmetics, and linens. Greek olives and olive oil were exported to the rest of the Empire.
