The Grand Duchy of Rivienland is a colossal, genial nation, ruled by Grand Duke Willem-Christoffel the Fourth with an even hand, and notable for its museums and concert halls, ban on automobiles, and punitive income tax rates. The compassionate, hard-working, devout population of 5.379 billion Rivienlanders have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The enormous government juggles the competing demands of Education, Environment, and Administration. It meets to discuss matters of state in the capital city of Hindeveen. The average income tax rate is 68.3%.

The all-consuming Rivienlandian economy, worth 314 trillion Rivenlander guilders a year, is highly specialized and mostly made up of the Beef-Based Agriculture industry, with significant contributions from Book Publishing and Cheese Exports. State-owned companies are reasonably common. Average income is 58,387 Rivenlander guilders, and evenly distributed, with the richest citizens earning only 3.6 times as much as the poorest.

The recently unemployed can often be seen at the local homeless shelter, travelers are subject to extensive searches if beet stains are visible on their clothing, kindergartners' favourite dance move is the stop-drop-and-roll, and thousands of children die every day from easily curable illnesses. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Rivienland's national animal is the Rivienlander yellow warbler, which is also the nation's favorite main course, and its national religion is Catholicism.

Rivienland is ranked 115,722^nd in the world and 281^st in Forest for Highest Wealthy Incomes, with 106,337 Standard Monetary Units.
