In Andalusia, of which Seville is the capital, the authorities want to exhume his body after passing a regional law designed to reinvigorate Spain’s 2007 “law of historical memory.” That measure offered state support for families wanting to unearth bodies of relatives killed during the civil war or who suffered as a political consequence of Franco’s regime.

The law also ordered the removal of all public symbols of Franco’s regime.

The Socialist government of the time offered financing to excavate mass war graves and commemorate Franco’s victims. But the conservative government of Prime Minister Mariano Rajoy, who was elected in late 2011, removed state support for such projects, warning against reopening old wounds in Spanish society.

As a result, enforcement of the law has been erratic, shelved by Mr. Rajoy’s government but applied vigorously in parts of the country, particularly those where left-wing politicians won office in local elections in 2015.

Queipo de Llano, who was among the military leaders of the July 1936 coup that set off the civil war, swiftly took control over Seville and then conquered the rest of southern Spain, while making radio broadcasts urging civilians to wipe out left-wing opponents. After the war, however, he was sidelined by Franco as a possible rival.
