Rexmania is a fictional country that I created this year. It is the largest country in its universe with a land area of 250 square miles. If you look at the Rexmanian mainlands geography: 29% Rainforest, 21.8% tropical forest, 14.5% Forest, 10.9% Swamps, Plains 5.08%, 5.74% mountains, Deserts 4.14%, Outback 2.54%, tundras who have 3.85% and Ice 2.4%. Rexmania would be one # in the economy thanks to its multi-diverse ecosystems and biomes in the mainland, its huge empire, resources, oil, technology, biodiversity, etc., which leads it having $372,909,499 in its GDP.  It controls most of the its mainlands natural resources of oil, gas, rare, minerals, etc. which would play a key role in the energy and mining industry shaping the future of global energy policies, prices, and sustainability. Rexmania's domination of the global financial market would likely house some of the largest banks, which could help stock citizens, entrepreneurs, and financial institutions. Its currency, the Rexordian dollar, could become a big global reserve currency like the US Dollar, given the size of the economy, and the Rexmanian Imperial Bank would have a huge influence over global interest rates, inflation, and economic stability over the empire and the world. If the Rexordian Dollar becomes a global reserve currency, many countries with small economies would heavily depend on Rexmania's markets and industries for their imports and exports, and many countries would try to seek with Rexmania, which align their economies on Rexmanian interests and markets. The Rexmanian Imperial Military was the federal army for Rexmania, which is the largest army in the army in world with 11 million active personnel and 15 million reserve personnel which makes it the largest military in the world with branches such as the Rexmanian Imperial Army for the ground, the Imperial Air Guard for the air, the Imperial Navy for situations that happen on water, the Imperial Marine Corps for conducting operations on land, sea, air, and space, and the Rexmanian Space Force which focus on military operations in space. The Rexmanian Military would be at the forefront of military technology from AI, Cyborgs, Terminators, robot animals, Dinosaurs, military animals, cyber warfare, and possibly bioengineered soldiers or animals, which could revolutionize warfare forever, creating a blend of cutting-edge technologies and biological entities, which would inspire other nations to do the same. Rexmania's huge military presence around the empire would help it to have a global military reach with its navy helping Rexmanian and international ships during piracy attacks and rescues, and military bases around the world that help them to have a presence in every country, continent, ocean, and key geostrategic regions around the world. The Empire of Rexmania would use its economic clout or military to punish or control other nations. Rexmania would dominate space exploration and militarize space by controlling satellite systems, developing space stations, and potentially weaponizing space itself, which would affect global communication networks and control space infrastructure like the internet, TVs, electricity, and etc. Rexmania is a Federal Autocrat Imperial Monarchy under an Imperial Royal family led by an emperor and empress who held supreme authority over national laws and policies with the President and prime minister. However, state and colonial governments have some self-governance and decision-making power. Regional or state governments would have administrative structures and officials responsible for local governance. They might handle State law enforcement, state education, state infrastructure, taxes for the state to fund government things, their economic development, and Rexmanian inventions include ultra 3d movies, bioengineered humans or creatures, powerful robots, ultra graphic video games, artificial continents, the Terraformer machine which allows people or nations to build artificial islands or continents faster and quicker, the robot dinosaurs, first real dragons, the first man made spaceship, and etc.
