The Empire of Imperial of Mankind is a colossal, cultured nation, ruled by Overlord with an even hand, and notable for its pith helmet sales, compulsory military service, and punitive income tax rates. The hard-nosed population of 7.868 billion Imperial of Mankindians 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 large government juggles the competing demands of Education, Healthcare, and Defense. It meets to discuss matters of state in the capital city of X-COM HQ. The average income tax rate is 81.3%, and even higher for the wealthy.

The frighteningly efficient Imperial of Mankindian economy, worth 851 trillion Republic credits a year, is quite specialized and led by the Information Technology industry, with significant contributions from Tourism, Arms Manufacturing, and Book Publishing. State-owned companies are reasonably common. Average income is an impressive 108,263 Republic credits, and distributed extremely evenly, with little difference between the richest and poorest citizens.

People caught mistreating Imperial of Mankind's flag generally wind up in a great deal of pain, the nation is currently revamping its entire education system, the military recognizes no difference between male and female soldiers, and infantry are nicknamed "mushrooms" because they get fed crap and are left in the dark. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Imperial of Mankind's national animal is the Pig, which frolics freely in the nation's many lush forests, and its national religion is Holy Emperor and Goddess.

Imperial of Mankind is ranked 68,559^th in the world and 100^th in The Glorious Nations of Iwaku for Largest Populations, with 7.87 billion capita.
