Rome

Rome was founded in Rome in 753BC by the Romulans out of Star Wars. The city was built in a day, and once completed it was the largest Lego city in the entire ancient world. With a society founded on republicanism, citizenship and the violent conquest of its neighbours, Rome thrived, and over the centuries Rome built up a land empire of several acres.

Eventually the Roman empire grew so large as to be administratively unwieldy, and began to collapse under its own weight like a badly-made civilisation pie.
The decline was exacerbated by several barbarian holiday groups, including the famous 'Tour of '09' by Alaric the Goth and his band of lank-haired Camdenites, who rampaged through Italy drunkenly chanting and throwing plastic chairs.

Today little remains of the empire except some ruins and a few packets of souvenir 'Gladiator' biscuits.
