Greece was a Roman province in all aspects from 146BC - AD86. The Greeks
wanted their independence, though, and when the Pontian king Mithridates
VI started invading Roman territories many Greek states supported him.
This proved to be a disastrous decision, for the Roman army answered by
chasing Mithridates out of Greece and by sacking Athens, Corinth and a
large part of central Greece. From now on Greece had lost any commercial
power, and basically only art and philosophy remained a major influence.
