1923 Spanish general election
The 1923 Spanish general election was held on Sundays, 29 April and 13 May 1923, to elect the 20th Restoration Cortes of the Kingdom of Spain. All 409 seats in the Congress of Deputies were up for election, as well as 180 of 360 seats in the Senate. This would be the last election under the "turno" system, as the Cortes would be dissolved and the Constitution suspended as a result of a military coup in September 1923 staged by Captain General Miguel Primo de Rivera. Primo de Rivera would establish a dictatorship which would last  until 1930. In 1931, the Second Spanish Republic would be proclaimed. Overview. Electoral system. The Spanish Cortes were envisaged as "co-legislative bodies", based on a nearly perfect bicameralism. Both the Congress of Deputies and the Senate had legislative, control and budgetary functions, sharing equal powers except for laws on contributions or public credit, where the Congress had preeminence. Voting for the Cortes was on the basis of universal manhood suffrage, which comprised all national males over twenty-five, having at least a two-year residency in a municipality and in full enjoyment of their civil rights. Voting was compulsory  except for those older than 70, the clergy, first instance judges and public notaries. For the Congress of Deputies, 173 seats were elected using a partial block voting in 44 multi-member constituencies, with the remaining 236 being elected under a one-round first-past-the-post system in single-member districts. Candidates winning a plurality in each constituency were elected. In constituencies electing ten seats or more, electors could vote for no more than four candidates less than the number of seats to be allocated; in those with more than eight seats and up to ten, for no more  than three less; in those with more than four seats and up to eight, for no more than two less; in those with more than one seat and up to four, for no more than one less; and for one candidate in single-member districts. Additionally, in single-member districts where candidates ran unopposed, as well as in multi-member districts where the number of candidates was equal or less than the number of seats to be filled, candidates were to be automatically proclaimed without an election as outlined under Article 29 of the electoral law. The Congress was entitled  to one member per each 50,000 inhabitants, with each multi-member constituency being allocated a fixed number of seats: 13 for Barcelona and Madrid, 6 for Valencia, 5 for La Coruña, Palma, Santander and Seville, 4 for Alicante, Almería, Badajoz, Córdoba, Huelva, Jaén, Lugo, Málaga, Murcia and Oviedo and 3 for Alcázar de San Juan, Alcoy, Algeciras, Bilbao, Burgos, Cádiz, Cartagena, Castellón de la Plana, Ciudad Real, El Ferrol, Gijón, Granada, Jerez de la Frontera, Las Palmas, Lérida, Llerena, Lorca, Orense, Pamplona, Pontevedra, San Sebastián, Santa Cruz de Tenerife, Tarragona, Valladolid, Vera, Vigo and Zaragoza. The law also provided for  by-elections to fill seats vacated throughout the legislature. For the Senate, 180 seats were indirectly elected, with electors voting for delegates instead of senators. Elected delegates—equivalent in number to one-sixth of the councillors in each municipal corporation—would then vote for senators using a write-in, two-round majority voting system. The provinces of Barcelona, Madrid and Valencia were allocated four seats each, whereas each of the remaining provinces was allocated three seats, for a total of 150. The remaining 30 were allocated to a number of institutions, electing one seat each—the Archdioceses of Burgos, Granada , Santiago de Compostela, Seville, Tarragona, Toledo, Valencia, Valladolid and Zaragoza; the Royal Spanish Academy; the Royal Academies of History, Fine Arts, Sciences, Moral and Political Sciences and Medicine; the Universities of Madrid, Barcelona, Granada, Oviedo, Salamanca, Santiago, Seville, Valencia, Valladolid and Zaragoza; and the Economic Societies of Friends of the Country from Madrid, Barcelona, León, Seville and Valencia. An additional 180 seats comprised senators in their own right—the Monarch's offspring and the heir apparent once coming of age; Grandees of Spain of the first class; Captain Generals of the Army and the Navy Admiral; the Patriarch of the  Indies and archbishops; as well as other high-ranking state figures—and senators for life (who were appointed by the Monarch). Election date. The term of each chamber of the Cortes—the Congress and one-half of the elective part of the Senate—expired five years from the date of their previous election, unless they were dissolved earlier. The Monarch had the prerogative to dissolve both chambers at any given time—either jointly or separately—and call a snap election.
