The April Fool's Fan of Imperio de Castilho is a massive, environmentally stunning nation, ruled by General Anhanguera with an even hand, and notable for its pith helmet sales, daily referendums, and sprawling nuclear power plants. The compassionate, devout population of 3.427 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 86.8%, and even higher for the wealthy.

The frighteningly efficient Castilhian economy, worth 541 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 158,067 dollars, and evenly distributed, with the richest citizens earning only 3.0 times as much as the poorest.

The government officially wants you to slow down and speak more clearly, psychiatrists bizarrely accompany General Anhanguera to meetings with foreign heads of state, the people's love for General Anhanguera is little more than self-preservation, and soldiers who shoot themselves in the foot are regarded as heroes. Crime, especially youth-related, is totally unknown, thanks to a 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 56,877^th in the world and 1,680^th in The North Pacific for Highest Foreign Aid Spending, scoring 545.78 on the Clooney Contribution Index.
