The Imperium of Leonism is a titanic, socially progressive nation, ruled by Imperator Konsul Leo I with an even hand, and remarkable for its smutty television, free-roaming dinosaurs, and national health service. The hard-nosed, humorless population of 22.824 billion Imperials are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The large government juggles the competing demands of Defense, Education, and Law & Order. It meets to discuss matters of state in the capital city of Leestcheck. The income tax rate is 100%.

The frighteningly efficient imperial economy, worth a remarkable 7,873 trillion Imperialmarks a year, is quite specialized and led by the Information Technology industry, with major contributions from Arms Manufacturing, Book Publishing, and Tourism. State-owned companies are reasonably common. Average income is an amazing 344,946 Imperialmarks, and evenly distributed, with the richest citizens earning only 2.1 times as much as the poorest.

Public loudspeakers constantly tell citizens they are "happy people", East Lebatuckese astronauts' favorite game during downtime on the Multinational Space Station is 'I Spy', the Smalltopian embassy doubles as an electoral campaign headquarters, and politicians are often found scavenging bins at night to supplement their income. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Leonism's national animal is the Blaumeise, which frolics freely in the nation's many lush forests.

Leonism is ranked 1,043^rd in the world and 48^th in Lazarus for Most Eco-Friendly Governments, scoring 15,455.8 on the Dolphin Recycling Awareness Index.
