The Shroom Empire of New Mushroom Kingdom is a gargantuan, socially progressive nation, ruled by Kid-Emperor Napoleon II with an iron fist, and notable for its flagrant waste-dumping, smutty television, and irreverence towards religion. The hard-nosed, hard-working, cynical, humorless population of 29.938 billion Mushrooms are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The medium-sized, corrupt government juggles the competing demands of Defense, Law & Order, and Industry. It meets to discuss matters of state in the capital city of Toad Town. The average income tax rate is 91.9%, and even higher for the wealthy.

The frighteningly efficient Mushroomian economy, worth an astonishing 12,270 trillion mushroom coins a year, is broadly diversified and mostly comprised of black market activity, especially in Information Technology, Arms Manufacturing, Retail, and Uranium Mining. State-owned companies are reasonably common. Average income is an amazing 409,850 mushroom coins, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Death row inmates cower in fear at the phrase "one-year anniversary", there is a disproportionate number of poor people in prison, it can be a real jungle in a modern courtroom, and Kid-Emperor Napoleon II is considering changing the nation's name to Blackacre. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. New Mushroom Kingdom's national animal is the mushroom, which teeters on the brink of extinction due to widespread deforestation.

New Mushroom Kingdom is ranked 2,314^th in the world and 1^st in Vissella for Lowest Crime Rates, with 139.52 law-abiding acts per hour.
