The United States of Earth (often just the confederacy) were a confederacy of 32 states and after the Great Earth War the supreme power of the earth.
After the big crisis in the 2040s 32 states founded under the command of the NATO the confederacy in 2050. Their goal was to save the earth and to stop mankind from destroying the planet and themselves. However, not all states wanted to become a member of the confederacy so in 2053 the Great Earth War started. After 11 years of war the confederacy won and united mankind. Riots and coup attempts holded on until the founding of Project Eden which gave hope to colonize a other planet.
