At one time the Selecuids owned most of the known world and were at the gates of Rome. After Rome was defended the Julii, Brutii and Scipii launched a counter-attack to retake Italy.
After Italy was secured Greece was then invaded by the Julii and the Scipii. After much bloodshed Greece was retaken for the glory of Rome.
Now you have a choice ... Do you continue on into Turkey and destroy the Selecuids once and for all or do you halt your progress to the east and take out the Britons who own Britannia, Gaul and Germania?
