The Grand Duchy of Diano is a mammoth, environmentally stunning nation, ruled by Grand Duke Maurizio I with a fair hand, and remarkable for its multi-spousal wedding ceremonies, daily referendums, and absence of drug laws. The compassionate, hard-working, democratic, devout population of 7.007 billion Dianese hold their civil and political rights very dear, although the wealthy and those in business tend to be viewed with suspicion.

The large government juggles the competing demands of Defense, Law & Order, and Administration. It meets to discuss matters of state in the capital city of Diano Marina. The average income tax rate is 55.6%, and even higher for the wealthy.

The all-consuming Dianese economy, worth 498 trillion Dianese Lire a year, is quite specialized and led by the Furniture Restoration industry, with major contributions from Gambling, Pizza Delivery, and Cheese Exports. Average income is 71,199 Dianese Lire, and evenly distributed, with the richest citizens earning only 3.0 times as much as the poorest.

Grand Duke Maurizio I can finally stop kneading the dough and start rolling in it instead, programmers often reinvent the wheel, foreign workers are flooding in as Dianese Lire flood out, and national chefs believe that you can eat anything so long as you deep fry it first. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Diano's national animal is the Seagull, which soars majestically through the nation's famously clear skies, and its national religion is Girolaismo.

Diano is ranked 110,083^rd in the world and 39^th in Carcassonne for Largest Populations, with 7.01 billion capita.
