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 for Revolutionary War General Francis Marion. 

Marion County is in the heart of the Willamette Valley, with the Willamette River as its western boundary and the Cascade Range on the east. Salem is the county seat and 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 Marion County Court presided over the county until January 1, 1963, when the court was abolished and replaced by a Board of Commissioners.
