The Empire of Prothean is a huge, safe nation, renowned for its compulsory military service, keen interest in outer space, and punitive income tax rates. The hard-working, devout population of 358 million Protheans 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 prioritizes Defense, with Spirituality, Law & Order, and Administration also on the agenda. The average income tax rate is 54.3%.

The strong Protheanian economy, worth 23.6 trillion Proteas a year, is led by the Arms Manufacturing industry, with significant contributions from Trout Farming, Uranium Mining, and Information Technology. Average income is 66,029 Proteas, and evenly distributed, with the richest citizens earning only 4.6 times as much as the poorest.

Burial ceremonies have become as routinised as tax forms, almost half of the child population live rough on the streets, cigarettes are dead-cheap, and the government is attempting to impose a new national language on the public. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Prothean's national animal is the Caveman, which teeters on the brink of extinction due to widespread deforestation.

Prothean is ranked 12,396^th in the world and 1^st in The Nuclear Alliance for Most Cheerful Citizens, with 54.76 Percentage Of Water Glasses Perceived Half-Full.
