Terran Systems Republic

The Terran Systems Republic (abbreviated TSR), commonly called the Terran Republic or simply the Republic, is a country encompassing most of human space. It is the sole superpower of the Modern Age, the largest and most populous polity in human history. It is a unitary state and functions as a representative democracy with a unicameral legislature. It has inherited the classical three-branch separation of powers from early terran democratic states. Its capital planet is Earth (Terra).

The TSR was declared in 2375 during the Coalition Wars, 25 years after the dissolution of the Stellar Federation. The change from a federal to a unitary system stems from the failure of the Federation to prevent separatist sentiments among the colonial population. The TSR aims to unite all of humanity under a single banner, prevent future wars, and promote total equality between planets regardless of demography or spatiography.
