The Pelycosaur Republic of Dimetrodon Empire is a massive, genial nation, ruled by Maximilien Robespierre with an even hand, and remarkable for its keen interest in outer space, ubiquitous missile silos, and irreverence towards religion. The compassionate population of 4.644 billion Dimetrodons enjoy extensive civil rights and enjoy a level of social equality free from the usual accompanying government corruption.

The large, liberal government juggles the competing demands of Education, Environment, and Defense. It meets to discuss matters of state in the capital city of Synapsid City. The average income tax rate is 65.1%, and even higher for the wealthy.

The thriving Dimetrodon economy, worth 357 trillion pesos 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 dominated by the Tourism industry, with significant contributions from Information Technology, Book Publishing, and Beef-Based Agriculture. Average income is 76,966 pesos, and evenly distributed, with the richest citizens earning only 2.5 times as much as the poorest.

Pocket dialling is a criminal offence, the Communist Party claims that selling things for profit isn't necessarily capitalism, anti-government web sites are springing up, and the nation's politicians are acknowledged as the most polite in the region to the dismay of comedians everywhere. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Dimetrodon Empire's national animal is the Dimetrodon, which frolics freely in the nation's many lush forests.

Dimetrodon Empire is ranked 281,552^nd in the world and 5,590^th in the Rejected Realms for Largest Furniture Restoration Industry, scoring -6.93 on the Spitz-Pollish Productivity Index.
