The Republic of Mercia Regnum is a massive, efficient nation, ruled by MatBoyler with an even hand, and notable for its compulsory military service, multi-spousal wedding ceremonies, and state-planned economy. The hard-nosed, hard-working, devout population of 4.091 billion Mercians 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 relatively small, corrupt government juggles the competing demands of Defense, Education, and Industry. It meets to discuss matters of state in the capital city of Tamworth. Citizens pay a flat income tax of 29.5%.

The frighteningly efficient Mercian economy, worth 540 trillion Pounds a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is broadly diversified, is led by the Arms Manufacturing industry, with major contributions from Information Technology, Tourism, and Beef-Based Agriculture. Average income is an impressive 132,044 Pounds, with the richest citizens earning 5.8 times as much as the poorest.

There's a lot of mouth-breathers about these days, disadvantaged youths often commit felonies to enhance their educational prospects, street crime is on the rise as police officers spend most of their time in prisons, and the sun now sets on the Mercian Empire. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Mercia Regnum's national animal is the Falcon, which soars majestically through the nation's famously clear skies, and its national religion is Celtica.

Mercia Regnum is ranked 149,888^th in the world and 4,232^nd in the West Pacific for Most Politically Free, scoring 38.1 on the Diebold Election Inking Scale.
