In spite of this, Andalusia was never recognised as a "historic nationality" in the 1978 constitution. This caused a great deal of indignation at the time and fired the fuse of a popular campaign which would lead the region seeking autonomy under the "vía rápida" (fast route) proposed for the historic nationalities by article 151 of the Spanish constitution. The "fast route" required an approved referendum by an absolute majority of all eligible voters in the region as well as in each constituent province. The referendum vote on 28 February 1980 did succeed in gaining the absolute majority of eligible voters in the proposed region, and in all provinces except for Almería, where it fell just short of a majority of all "eligible voters". Due to this, Andalusia could not achieve autonomous status under the "fast route" proposed by the Spanish constitution.
