Spain's conservative opposition will boycott the start of official commemorations marking the 50th anniversary of right-wing dictator Francisco Franco's death, laying bare the enduring divisiveness of his legacy.
The general overthrew a democratic republic in a brutal civil war that killed hundreds of thousands and ruled with an iron fist from 1939 until his death in 1975.
Socialist Prime Minister Pedro Sanchez has announced around 100 events in 2025 to "showcase the great transformation achieved" in the half-century since the European country initiated its democratic transition.
Madrid's Reina Sofia art museum -- home to Pablo Picasso's "Guernica" painting, one of the most famous anti-Franco works -- will host the first ceremony on Wednesday.
Sanchez will lead it but neither King Felipe VI nor the leader of the main conservative Popular Party (PP), Alberto Nunez Feijoo, will attend.
Feijoo believes the initiative is an opportunistic ploy by the minority leftist government to distract attention from its political and legal woes.
Corruption investigations are ongoing against Sanchez's wife and political allies, while the Socialists have to negotiate painstakingly with an array of fringe and separatist parties to pass legislation.
The commemorations planned in schools, universities, museums and streets are the work of a government which "in its desperation constantly looks to the past", Feijoo said.
The Socialists have retorted by pointing to the origins of the PP, born in 1989 as the successor to the Popular Alliance, founded in 1976 by a former Franco minister.
Far-right Vox, the third-largest force in parliament, will also snub the programme. One of its MPs recently said in parliament that Franco's rule "was not a period of darkness, as this government makes out, rather a stage of reconstruction, progress and reconciliation".
At the other end of the political spectrum, the hard-left Podemos has called the commemorations a "facade" to cover up the scant compensation for the dictatorship's victims.
Sanchez passed a "democratic memory" law in 2022 aiming to revive their memory, including the creation of a register of victims and the removal of Francoist symbols.
But the law has not tried or convicted any ex-Franco officials accused of crimes and who remain alive as they benefit from an amnesty approved during the transition, to the disappointment of survivors.
The polarising memory of the 1936-1939 civil war and Franco stems from the regime's tame demise, according to Joan Maria Thomas, professor of contemporary history at the University of Rovira i Virgili.
An ailing 82-year-old Franco passed away peacefully in hospital, in contrast with the spectacular collapse of Nazi Germany and fascist Italy during World War II or the Carnation Revolution that overthrew Portugal's right-wing dictatorship in 1974.
