The April Fool's Fan of Imperio de Castilho is a massive, safe nation, ruled by General Anhanguera with an even hand, and remarkable for its avowedly heterosexual populace, compulsory military service, and punitive income tax rates. The compassionate, devout population of 3.446 billion Castilhians 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, corrupt government juggles the competing demands of Defense, Law & Order, and Administration. It meets to discuss matters of state in the capital city of Guaricana. The average income tax rate is 87.9%, and even higher for the wealthy.

The frighteningly efficient Castilhian economy, worth 540 trillion dollars a year, is led by the Arms Manufacturing industry, with significant contributions from Tourism, Information Technology, and Book Publishing. Average income is an impressive 156,792 dollars, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Crocodile roadkill is smeared across the asphalt of the new Formula One track, the nation is automatically assumed to be the source of all unmarked weapons, signatures have been replaced with illegible scribbles, and welfare recipients are milking the government for all they've got. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Imperio de Castilho's national animal is the fragata, which frolics freely in the nation's many lush forests, and its national religion is Christianity.

Imperio de Castilho is ranked 11,885^th in the world and 357^th in The North Pacific for Most Patriotic, with 59.64 flags saluted per person per day.
