The Duchy of Masovia is a titanic, pleasant nation, ruled by Duke Bolesław VII with an even hand, and remarkable for its ubiquitous missile silos. The hard-nosed, hard-working population of 20.799 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 26.4%.

The strong Masovian economy, worth a remarkable 1,015 trillion zloties a year, is led by the Beef-Based Agriculture industry, with major contributions from Gambling, Cheese Exports, and Information Technology. Average income is 48,830 zloties, and evenly distributed, with the richest citizens earning only 4.9 times as much as the poorest.

Ice-filled coffins are ominously positioned in the corner of every hospital ward, the MBI Channel Tunnel project is plagued by delays, it is a crime to operate a combine harvester while intoxicated, and popular websites like NationStates are blocked for "national security". Crime is moderate. Masovia's national animal is the eagle, which can occasionally be seen dodging aircraft in the nation's cities.

Masovia is ranked 82,128^th in the world and 23^rd in Terranova for Largest Cheese Export Sector, scoring 3,717.5 on the Mozzarella Productivity Index.
