Career
He came from an impoverished background, being forced to earn a living from a very early age and trained as a clockmaker. He was imprisoned in Sestao, Spain, following his participation in a political rally, when he was fifteen years old. He took part in the Confederación Nacional del Trabajo (CNT) Congress of 1918, being unanimously elected editor-in-chief of the group"s newspaper Solidaridad Obrera.
Under his direction, the paper mounted a violent campaign against the local police force, accusing its leader of being a hireling of Imperial Germany.
In April 1919, after Catalonia was shaken by the Canadenca protests, Pestaña was arrested and detained, and the paper banned. He left for Bolshevist Russia in 1920, in order to be present at the 2nd Communist International Congress and the preliminary sessions of the Profintern.
There he met Vladimir Lenin, Leon Trotsky, Grigory Zinoviev, and other Bolshevik leaders. Upon his return, he was yet again detained.
Conflicts with the government and the anarchists
In August 1922, he was the victim of an assassination attempt while giving a speech in Manresa, as part of the violent repression measures taken by the Spanish authorities.
The indignation caused throughout Spain by news of this act brought the dismissal of several government officials, as well as an end to legislation that had made allowed for the murder of trade union activists. After Seguí fell victim to an assassination, Pestaña remained the main figure of the moderate CNT. This position allowed him to oppose, together with Joan Peiró, all attempts by the 1927-founded Federación Anarquista Ibérica (FAI) at assuming control of the CNT during the dictatorship of Miguel Primo de Rivera. Split with the CNT
After the proclamation of the Second Spanish Republic in 1931, the conflict between Pestaña"s group and FAI deepened: Pestaña initiated the issue of Manifiesto de los Treinta/Manifest dels Trenta ("Manifesto of the Thirty"), a clear condemnation of the Federación"s tactics, one which got him expelled from the CNT in August.
In October, with the start of the Spanish Civil War, he was appointed general subcommisioner for War, but had to resign due to bad health in December.
He died soon after, and the Syndicalist Party did not survive the end of the conflict. The trade-unionists will act lawfully as long as the law is respected.
A homage to Pestaña was made on 13 February 1938 at the Fuencarral Theater in Madrid, in conmemoration of his birth. The tribute was attended by speakers of the Syndicalist Party, the Communist Party of Spain, the Popular Front, the Iberian Anarchist Federation, the Republican Left and the National Confederation of Labour.
A square in the Nou Barris district of Barcelona is named Ángel Pestaña in his honour.
