For all intents and purposes, the history of contemporary Spain began with the death of dictator Francisco Franco on the 20 November 1975, the accession of King Juan Carlos I to the throne and the establishment of the parliamentary monarchy. In 1978, the current Spanish Constitution of 1978 was signed and the status of Spain's autonomous entities (autonomías) was defined.
In the uncertainty after Franco's death, the political situation could have taken one of three turns:
In his coronation speech, the King had opened the possibility for reform along the lines of constitutional monarchy. However, for this to be possible, high-ranking officials from the previous regime had to be ejected from power.
The first act the King did was to name Torcuato Fernández Miranda, his old teacher, as the President of the Cortes and of the Consejo del Reino. This gave the King control over the Cortes and provided him with critical assistance to dismantle the old regime within a legal framework. Torcuato Fernández Miranda was despised by the falangists and was a staunch supporter of reform.
The new government included many "reformists" like Manuel Fraga, who was the visible head of the government. Manuel Fraga often argued with the opposition (even imprisoning leaders of the Platijunta, a hybrid coalition of the Junta Democrática and the Plataforma de Convergencia Democrática), whom he wanted to get out of the way. Fraga preferred "slow evolution" into democracy, unlike the King. Carlos Arias Navarro consistently impeded the King's wishes of accelerating reform. As a result, the King had to get rid of him, as it seemed he had caved in under pressure from the bunker.
