The Duchy of Masovia is a gargantuan, pleasant nation, ruled by Duke Bolesław VII with an even hand, and notable for its burgeoning eagle population. The hard-nosed, hard-working population of 16.769 billion Masovians 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 medium-sized government juggles the competing demands of Defense, Education, and Healthcare. It meets to discuss matters of state in the capital city of Warszawa. The average income tax rate is 25.7%.

The strong Masovian economy, worth 817 trillion zloties a year, is led by the Beef-Based Agriculture industry, with major contributions from Gambling, Information Technology, and Cheese Exports. Average income is 48,761 zloties, with the richest citizens earning 5.1 times as much as the poorest.

More and more students are taking up a career in medicine, Duke Bolesław VII has just been declared ruler of Masovia in an international press conference, panels from bankrupt rooftop solar companies are used as props for sci-fi B-movies, and a major religion has been named as Masovia's national religion. Crime is relatively low, thanks to a capable police force and progressive social policies in education and welfare. Masovia's national animal is the eagle, which can occasionally be seen dodging aircraft in the nation's cities.

Masovia is ranked 274,365^th in the world and 62^nd in Terranova for Most Extreme, scoring 7.01 on the Paul-Nader Subjective Decentrality Index.
