During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1965, the neighboring municipalities of Davik and Hornindal were dissolved and split up among their neighbors. Eid municipality gained all of Davik that was north of the Nordfjorden and east of and including the village of Lefdal. (Population in that area was 654.) All of Hornindal municipality west of and including the villages of Navelsaker and Holmøyvik (population: 310) was also merged into Eid. After this merger, Eid's total population was 4,532. At this point, Eid gained a third sub-parish from the former municipality of Davik: Kjølsdalen. Then on 1 January 1992, the village of Lote and its surrounding area (population: 152) was transferred from Gloppen Municipality to Eid.
