Regional elections were held in Spain during 1991 to elect the regional parliaments of thirteen of the seventeen autonomous communities: Aragon, Asturias, the Balearic Islands, the Canary Islands, Cantabria, Castile and León, CastillaâÂÂLa Mancha, Extremadura, La Rioja, Madrid, Murcia, Navarre and the Valencian Community. 784 of 1,178 seats in the regional parliaments were up for election. The elections were held on 26 May (concurrently with local elections all across the country).
Determination of election day varied depending on the autonomous community, with each one having competency to establish its own regulations. Typically, thirteen out of the seventeen autonomous communitiesâÂÂall but Andalusia, the Basque Country, Catalonia and GaliciaâÂÂhad their elections fixed for the fourth Sunday of May every four years, to be held together with nationwide local elections.
