The Imperium of Romae in Perpetuum is a titanic, efficient nation, ruled by Gemellus Caesar with an iron fist, and notable for its pith helmet sales, infamous sell-swords, and keen interest in outer space. The hard-nosed, hard-working, cynical, humorless, devout population of 18.97 billion Romans are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The medium-sized, corrupt, moralistic, well-organized government prioritizes Defense, although Law & Order, Industry, and Education are also considered important, while Social Policy and Welfare are ignored. It meets to discuss matters of state in the capital city of Nova Roma. Citizens pay a flat income tax of 90.5%.

The frighteningly efficient Roman economy, worth a remarkable 8,121 trillion Denarii a year, is broadly diversified and mostly comprised of black market activity, especially in Arms Manufacturing, Information Technology, Uranium Mining, and Retail. State-owned companies are reasonably common. Average income is an amazing 428,102 Denarii, but there is an enormous disparity between incomes, with the richest 10% of citizens earning 2,363,039 per year while the poor average 39,189, a ratio of 60.3 to 1.

It is illegal to distribute Girl Guide Cookies without an advanced food hygiene diploma, prime commercial land is being swamped with archaeological teams, families returning from international vacations are unable to get their children back into the country, and bouncers at the door of the sweet shop warn five-year-olds not to cause trouble. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Romae in Perpetuum's national animal is the Eagle, which is also the nation's favorite main course, and its national religion is Cultus Imperator.

Romae in Perpetuum is ranked 437^th in the world and 1^st in The Fourth Sovereign Charter for Largest Black Market, with 12,066 trillion Standard Monetary Units.
