History and general information
Marion County, then called Champooick, was created by the Provisional Government in 1843, 16 years before Oregon gained statehood. In 1849, the name was changed to Marion in honor of General Francis Marion.
The county, located in the heart of the Willamette Valley, has the Willamette River as its western boundary and the Cascade Range on the east. Salem, the county seat, is one of the valley’s oldest cities. Among its public buildings are the Marion County Courthouse, State Capitol, Capitol Mall buildings and Salem Civic Center. The county was presided over by the Marion County Court until January 1, 1963, when the court was abolished and replaced by a Board of Commissioners.
