That municipality only existed until 1845 when it was split into Nord-Audnedal and Sør-Audnedal. Those municipalities were later divided also. Sør-Audnedal was divided into Spangereid in 1899 and Nord-Audnedal was divided into Konsmo and Vigmostad in 1911. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. This is when the present-day municipality of Audnedal was created.
