The Sumatran Republic was a government based on the planet of Sumatra in the Mid Rim. Formed in 78 BBY after the first First Sumatran Civil War, it had to deal with conflicting interests. It almost broke down in 21 BBY, when the Second Sumatran Civil War was initiated by the Confederacy of Independent Systems during the Clone Wars, following the Separatists' failure to take the world themselves.
