The Fiefdom of The Third Imperium is a colossal, efficient nation, ruled by God-Emperor Leto Atreides II with an even hand, and notable for its public floggings, keen interest in outer space, and complete lack of public education. The hard-nosed, hard-working, democratic, devout population of 6.297 billion Third Imperiumians are either ruled by a sleek, efficient government or a conglomerate of multinational corporations; it's difficult to tell which.

The medium-sized, pro-business government is effectively ruled by the Department of Defense, with Industry also on the agenda, while Spirituality and Welfare receive no funds. It meets to discuss matters of state in the capital city of Onn. Citizens pay a flat income tax of 20.5%.

The frighteningly efficient Third Imperiumian economy, worth 534 trillion Spices a year, is quite specialized and led by the Arms Manufacturing industry, with major contributions from Gambling, Book Publishing, and Information Technology. Average income is 84,855 Spices, with the richest citizens earning 8.5 times as much as the poorest.

A typical fast food menu item could serve a small army, the government awards prizes to television shows featuring stereotype-breaking minority roles, UFO sightings are listed daily in the morning news, and military spending is on the increase. Crime, especially youth-related, is pervasive, probably because of the absence of a police force. The Third Imperium's national animal is the Sandworm, which frolics freely in the nation's many lush forests.

The Third Imperium is ranked 65,795^th in the world and 42^nd in Greater Sahara for Highest Wealthy Incomes, with 223,938 Standard Monetary Units.
