Guernica may not specifically be about Spain but rather about war and its victims. Still, looking back, we might qualify this statement. The mural also remains inescapably about what happened in Spain eighty years ago and all that was lost there.

Indeed, John Rockefeller tried to buy it, and, when the artist refused, paid for its recreation as a tapestry. Famously, the reproduction, which has been on display at the entrance of the United Nations Security Council since 1985, was covered with a large blue curtain on February 5, 2003. Journalists reported that the Bush administration had pressured officials to conceal the tapestry before Secretary of State Colin Powell and United Nations ambassador John Negroponte arrived there to press the case for war against Iraq.

Nevertheless, Guernica achieved its political as well as artistic goals. Picasso created a searing protest against the new face of war and fascism’s brutality. The mural depicts suffering: not only the suffering Picasso heard in the news from Spain but also a more universal suffering. Guernica almost immediately became legendary, and Berger called it “the most famous painting of the twentieth century.”

Instead we find timeless images — a falling woman, a Madonna and Child, a mother screaming, a child broken, a wounded soldier’s shattered corpse, a ménage of mutilated bodies and distorted faces, a twisted horse shrieking in agony. Only an electric light reminds us of modernity.

[A] profoundly subjective work — and it is from this that its power derives. Picasso did not try to imagine the actual event. There is no town, no aeroplanes, no explosion, no reference to the time of day, the year, the century, or the part of Spain where it happened. There are no enemies to accuse. There is no heroism. And yet the work is a protest — and one would know this even if one knew nothing of its history.

To a degree, this latter criticism rings true, but was misplaced. Guernica offers no hint of what was happening in Spain at the time. Nothing in the mural indicates where these events took place besides the horse and the bull, which both evoke Spanish culture. The late art critic John Berger described it as :

In July 1937, the mural was installed in the entrance to the Republic’s Spanish Pavilion amid controversy. The Right objected to the subject matter altogether, while the Left found it obscure.

Guernica , massive in size, composed in mixtures of black and gray and white, is a picture of an air raid. It is twenty-five and a half feet long and more than eleven and a half feet in height.

Still, the insurgent Popular Front government appointed him director of the Prado Museum in Madrid, in absentia, and Picasso undertook several projects sympathetic to the Republic and to raise funds on its behalf. The government in turn asked him to produce a mural for the 1937 Paris World’s Fair, and he agreed, though progress at first was slow. It was the April 26 attack at Guernica that moved him. He threw himself into the painting and in less than five weeks, astonishingly, had completed Guernica .

Then living in Paris, Picasso, fifty-five, was already well-known. Born in Spain in 1881, he went to Paris in 1900; he had visited Spain in 1934 but would never return.

In February 1936, Spain was sinking into a profound economic and social crisis. In response, voters elected a Popular Front government that represented an array of republicans, socialists, Communists, and even the independent Workers’ Party of Marxist Unification (POUM) — though the latter called it an “alliance with no future.”

The powerful anarchist workers’ organizations, the National Confederation of Labor (CNT) and the Iberian Anarchist Federation (FAI), broke with all past practice and abandoned their call for electoral abstention, which they sloganized as No Votad. This decision cemented the Left’s victory, inflicting a humiliating defeat on the center and the Right.

While revolution was not on the ballot, the election helped clear a path for one. By midsummer, a dual-power state developed in Barcelona, if not across all of Spain. In the countryside — Spain remained overwhelmingly rural — peasants seized the great estates and collectivized them; in cities, workers took control of factories and governments.

Then, in July, the Right — the fascists calling themselves nationalists — replied: the generals revolted. The uprising began in Spain’s North African colony Morocco, where an army of mercenaries, legionnaires, and Moroccans was assembled as the ruling class’s shock troops. Soon, fascist general Francisco Franco took the lead, crossing into Spain and commanding a drive to the north, where, in Madrid, Barcelona, Malaga, and the industrial centers of Asturias and Catalonia, the workers were in rebellion.

In these places, soldiers joined the workers; they mutinied, turned over their weapons to the revolutionaries, or were trapped in their barracks. If the generals meant to forestall the revolution, instead they provoked it.

George Orwell arrived in Barcelona that December, intent on writing newspaper articles about the conflict, but he soon joined a workers’ militia. He found:

Practically every building of any size had been seized by the workers and was draped with red flags or with the red and black flag of the anarchists; every wall was scrawled with the hammer and sickle and with the initials of the revolutionary parties; almost every church had been gutted and its images burnt. Churches here and there were being demolished systematically by gangs of workmen.

Orwell documented this in his classic account of revolution and counterrevolution, Homage to Catalonia , published in Britain in 1938, but not until 1952 in the United States. The French edition was not published until five years after his death. In the book, Orwell described the revolutionary change that had come over Barcelona:

Every shop and cafe had an inscription saying that it had been collectivized; even the boot blacks had been collectivized and their boxes painted red and black. Waiters and shop-walkers looked you in the face and treated you as an equal. Servile and even ceremonial forms of speech had temporarily disappeared. Nobody said “Señor” or “Don” or even “Usted”; everyone called everyone else comrade and “Thou,” and said “Salud” instead of “Buenos dias.”

This would not last. Franco’s troops, now backed by German and Italian arms, steadily advanced. As nationalist victories mounted, the situation in the Republic became increasingly desperate — only the epic battles at Jarama and Guadalajara saved Madrid. There, heroic resistance from Spanish militias and international brigades held off the fascists, although at great cost. These, tragically, were the last victories.

The middle classes responded by insisting that winning the war must come first and revolution, if at all, later — much later. The revolution, they claimed, was undermining the war effort and making the imagined intervention from the French or British impossible.

They demanded that the armed forces reinstate hierarchy and discipline, that the workers’ militias disarm, and that the peasant revolution come to an end. The increasingly large and powerful Communist Party, following the Soviet Union’s dictates, supported them.

In April, the tenth month of the war, Guernica, for centuries the center of Basque identity, was targeted by a squadron of Hitler’s Luftwaffe bombers, supplemented by a handful of planes from the Italian fascists. The London Times reported:

Guernica, the most ancient town of the Basques and the centre of their cultural tradition, was completely destroyed yesterday afternoon by insurgent air-raiders. The bombardment of the open town far behind the lines occupied precisely three hours and a quarter, during which the powerful fleet of aeroplanes consisting of three German types, Junkers and Heinkel bombers and Heinkel fighters, did not cease unloading on the town bombs weighing from 1000 lb. downward. . . The fighters meanwhile flew low from above the centre of the town to machine-gun those of the civilians who had taken refuge in the fields. The whole of Guernica was soon in flames except the historic Casa de Juntas.

The attack could not have come at a worse time for the Republic. While the fascist offensive continued, the Communist Party struck militarily against the POUM and the CNT. Five hundred people died in house-to-house fighting. The Republic outlawed POUM in June, and Stalinist agents murdered the party’s leader, Andres Nin, soon after. The prime minister, Largo Caballero, leader of the Spanish Socialist Workers Party and the Workers General Union (CGT) was forced from office. Although Picasso was painting Guernica at the time, and it was certainly discussed within his circle, his painting tells us next to nothing of his opinion of these events.

The German and Italian governments handed victory to Franco and his army, installing a fascist government that would last for thirty-six years. Soon all of Europe would be at their mercy.
