1977 Spanish general election cause Spanish transition to democracy
Background
The death of Francisco Franco in 1975 paved the way for Spain's transition from an autocratic, one-party dictatorship into a democratic, constitutional monarchy. As per the Succession Law of 1947, the Spanish monarchy was restored under the figure of Juan Carlos I, who quickly became the promoter of a peaceful democratic reform of state institutions. This move was supported by western countries, an important sector of Spanish and international capitalism, a majority of the opposition to Francoism—organized into the Democratic Convergence Platform and the Democratic Junta, which in 1976 would both merge into the Democratic Coordination—and a growing part of the Franco regime itself, weary of popular mobilization after the outcome of the Carnation Revolution in neighbouring Portugal in 1974. However, as incumbent Prime Minister Carlos Arias Navarro rejected any major transformation of the Spanish political system, rather supporting the preservation of Francoist laws, he was dismissed by the King in July 1976, who appointed Adolfo Suárez for the post.
Suárez's plans for political reform involved the transformation of Spanish institutions in accordance to the Francoist legal system through the approval of a "political reform bill" as a Fundamental Law of the Realm. This was meant as a step beyond Arias Navarro's plans to update—but preserve—the Francoist regime, with Suárez intending to implement democracy "from law to law through law"—in the words of Torcuato Fernández-Miranda—without the outright liquidation of the Francoist system as called for by opposition parties. Thus, on 18 November 1976, the 1977 Political Reform Act was passed by the Francoist Cortes, later ratified in a referendum on 15 December 1976 with overwhelming popular support. As set out in Suárez's scheme, the Act called for an electoral process to elect new Cortes that were to be responsible for drafting a democratic constitution.
