The former municipality of Åsskard (historically spelled Aasgaard) included the area around the Åsskardfjorden, north of the Hamnesfjorden, and east of the Trongfjorden.

On 1 July 1915, a southern district of Halsa Municipality (population: 114) was transferred to Aasgaard.

During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee.

This is likely referring to the fact that the Åsskard farm was situated in a narrow, low area between some mountains on the isthmus between the Åsskardfjorden and the Hamnesfjorden.

[9] The municipal council (Heradsstyre) of Åsskard was made up of 13 representatives that were elected to four year terms.
