The Fairhair dynasty (Norwegian: Hårfagreætta) was a family of kings founded by Harald I of Norway (commonly known as "Harald Fairhair", Haraldr inn hárfagri) which united and ruled Norway with few interruptions from the latter half of the 9th century. In the traditional view, this lasted until 1387, however, some modern scholars view this rule as lasting only three generations, ending with Harald Greycloak in the late 10th century. The moniker "Fairhair dynasty" is a retrospective construction: in their lifetime what little traces there are refer to them consistently as "Ynglings".
