Martian Congressional Republic

The Martian Congressional Republic is the governing body that rules over the nine billion inhabitants of Mars and is one of the two human superpowers. Their flag is reminiscent of Mars and its two moons, Phobos and Deimos.
The Republic is often in direct competition with 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.
