The Most Serene Republic of Roisin Dubh is a titanic, cultured nation, ruled by His Most Serene Mark with an iron fist, and remarkable for its keen interest in outer space, state-planned economy, and lack of airports. The compassionate, cynical, cheerful population of 13.394 billion Roisin Dubhians are ruled with an iron fist by the socialist government, which grants its people the freedom to do whatever they like so long as it doesn't involve getting richer than anybody else or challenging the government.

The enormous, socially-minded government juggles the competing demands of Education, Administration, and Environment. It meets to discuss matters of state in the capital city of Tír na nÓg. The average income tax rate is 99.8%.

The frighteningly efficient Roisin Dubhian economy, worth a remarkable 2,432 trillion Florins a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is quite specialized, is led by the Tourism industry, with significant contributions from Information Technology, Book Publishing, and Basket Weaving. Average income is an impressive 181,601 Florins, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Access to the woods is only granted to those who bring a small shrubbery, the army lures cannon fodder with promises of a college education, intoxicated AI mobile platforms are sometimes seen crashing through windows instead of being crashed by them, and museums stand half-empty as all foreign exhibits are returned to their countries of origin. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Roisin Dubh's national animal is the Wolf, which frolics freely in the nation's many lush forests.

Roisin Dubh is ranked 704^th in the world and 14^th in 10000 Islands for Most Eco-Friendly Governments, scoring 17,615.06 on the Dolphin Recycling Awareness Index.
