Martian Congressional Republic
The government of independent Mars in The Expanse: four billion people, a terraforming dream, and a navy that makes Mars the military equal of Earth.
The Martian Congressional Republic is the government of an independent Mars, one of the two human superpowers. Roughly four billion people live under it, far fewer than Earth's billions, yet the MCR holds equal standing through discipline and hardware: its society is organized like a long military campaign, its economy bends toward one generational project, terraforming Mars into a world with open sky, and its navy fields the most advanced warships in the Solar System. The Republic's cold rivalry with Earth's United Nations, and the two powers' shared habit of treating the Belt as a resource rather than a partner, supply the tension that frames this period.
