The Kingdom of the Carolinas of Aztec Tlahtocayotl is a massive, genial nation, ruled by King Kurt I of Carolina with an even hand, and renowned for its ubiquitous missile silos, irreverence towards religion, and devotion to social welfare. The compassionate population of 1.733 billion Carolinians 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, Welfare, and Healthcare. It meets to discuss matters of state in the capital city of Charolette. The average income tax rate is 45.2%.

The sizeable but inefficient Carolinian economy, worth 69.7 trillion Thalers a year, is led by the Trout Farming industry, with significant contributions from Automobile Manufacturing, Tourism, and Basket Weaving. State-owned companies are common. Average income is 40,225 Thalers, and evenly distributed, with the richest citizens earning only 4.1 times as much as the poorest.

Education is transforming people into first-rate snobs, rundown towns are frequently sold to billionaires for their pet projects, bizarre-looking creatures called 'Eagledogs' dominate wildlife preserves, and students at universities think exercise bikes are pieces of abstract art. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Aztec Tlahtocayotl's national animal is the Eagle, which is also the nation's favorite main course.

Aztec Tlahtocayotl is ranked 168,068^th in the world and 58^th in Callista for Most Scientifically Advanced, scoring 48.47 on the Kurzweil Singularity Index.
