Martian Congressional Republic
The Martian Congressional Republic is the governing body which rules over the four billion inhabitants of Mars. The Republic is often times in direct competition to Earth and its governing body, the United Nations. Although Mars has a significantly smaller population than Earth, the ruggedness of the people, as a result of the harsher environment and sparser resources, makes Mars a worthy counterweight to Earth’s power. The Martian Congressional Republic Navy, although smaller, is considered to be more advanced.
However, like Earth, they actively oppress the Belt and its people.
