On 1 January 2024, Østfold was re-established as an independent county, however without the former municipality of Rømskog, which was amalgamated with the Akershus municipality Aurskog-Høland in 202

}} Østfold is among the nation's oldest inhabited regions, with petroglyphs (rock drawings) and burial mounds throughout the area.
In the Viking Age, the area was part of Vingulmark, which in turn was part of Viken and included Båhuslen (which is now the Swedish province called Bohuslän). It was partly under Danish rule until the time of Harald Fairhair.
