The Grand Duchy of Great Dunmow is a colossal, genial nation, ruled by Grand Duke Willem Laurence von Amstel with an even hand, and notable for its barren, inhospitable landscape, state-planned economy, and punitive income tax rates. The devout population of 3.68 billion Dunnishes 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 Spirituality, Education, and Administration. It meets to discuss matters of state in the capital city of Stavenhearth. The average income tax rate is 52.2%, and even higher for the wealthy.

The large but underdeveloped Great Dunmowian economy, worth 110 trillion Dunmow Crowns a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector is dominated by the Trout Farming industry, with significant contributions from Arms Manufacturing, Retail, and Automobile Manufacturing. Average income is 30,091 Dunmow Crowns, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Ship captains always order a return to port at the slightest sign of rain, student athletes gaze forlornly at abandoned grey heronball fields, science centers and state of the art laboratories are ubiquitous, and advertisements for jobs in the sciences run in fashion magazines. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Great Dunmow's national animal is the grey heron, which teeters on the brink of extinction due to toxic air pollution.

Great Dunmow is ranked 187,955^th in the world and 2^nd in Imperium of Austria Hungary for Largest Arms Manufacturing Sector, scoring 1,933.91 on the Charon Conveyancy Index.
