The United Kingdom of Marie Byrd is a massive, efficient nation, ruled by King Terrance with an iron fist, and notable for its keen interest in outer space, anti-smoking policies, and devotion to social welfare. The hard-nosed, cynical, humorless, devout population of 4.052 billion Marie Byrdians are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The medium-sized, corrupt government juggles the competing demands of Defense, Education, and Industry. It meets to discuss matters of state in the capital city of Deheubarth. The average income tax rate is 68.5%.

The frighteningly efficient Marie Byrdian economy, worth 691 trillion Grant Island Pounds a year, is quite specialized and led by the Arms Manufacturing industry, with major contributions from Information Technology, Book Publishing, and Uranium Mining. Black market activity is rampant. State-owned companies are reasonably common. Average income is an impressive 170,544 Grant Island Pounds, and evenly distributed, with the richest citizens earning only 3.1 times as much as the poorest.

Snap elections are called over every minor impasse, it is a common belief that a sport isn't sport if there are no decapitations, any body part that can be cut off a person is no longer considered to be their property, and with great power generation comes great responsibility. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Marie Byrd's national animal is the Penguin, which frolics freely in the nation's sparkling oceans, and its national religion is Church of Marie Byrd.

Marie Byrd is ranked 198,436^th in the world and 216^th in Thaecia for Lowest Overall Tax Burden, scoring -55.55 on the Hayek Index.
