Peter Wiggin, the last Hegemon, restructured the Hegemony into the Free People of Earth. Soon after its founding, many smaller and weak countries joined the FPE in order to protect themselves from their more powerful neighbors. As the Muslim League, Chinese, and Indian empires collapsed, more influential and larger countries decided to join the alliance.
Years after its founding, the FPE was more commonly referred to as EarthGov. The last military ventures that the FPE exercised put down the last gasps of tribalism around 31 AX. The only country that still refused to join was the United States of America.
Each member country of the FPE had power and roles similar to how states worked in the United States of America. Before Peter Wiggin's death, he acted as the world leader, akin to the President of the United States. After the death of Wiggin, the Congress of the government had the ultimate control and the position of Hegemon was abolished.
The FPE had multiple capitals around the world to emphasize the equality of all nations. At first, its only capital was Blackstream, Brazil, but by 9 AX the cities of Bangkok, Rwanda, and Rotterdam had been added as well.
