Incorporated by the General Assembly on March 9, 1902, Clifton is one of only three towns in the county, the other two being the much more populous Vienna and Herndon. Clifton's history begins pre-colonially, when the area was used as hunting grounds by the local Dogue Native American tribe. A railroad siding was constructed here during the Civil War, and the area became titled as Devereux Station. A nearby neighborhood on the outskirts of the Clifton ZIP code has this name. Development of a village at the siding began in 1868 when a railroad depot, named "Clifton Station", was constructed.
