Following the Battle of Corinth in 146 BC, Greece came under Roman rule, ruled from the province of Macedonia. In 27 BC, Augustus organised the Greek peninsula into the province of Achaea. Greece remained under Roman control until the break up of the Roman empire, in which it remained part of the Eastern Empire. Much of Greece remained under Byzantine control until the end of the Byzantine empire in 1453 AD. Ancient Rome was a civilization that grew out of the city-state of Rome, originating as a small agricultural community founded on the Italian Peninsula in the 9th century BC. In its twelve centuries of existence, Roman civilization shifted from a monarchy to an oligarchic republic to an increasingly autocratic empire.
