Miguel De Unamuno

In 1901 Unamuno gave his well-known conference on the scientific and literary inviability of the Basque. According to Azurmendi, Unamuno went against the Basque language once his political views changed as a result of his reflection on Spain.

After his youthful sympathy for socialism ended, Unamuno gravitated towards liberalism. Unamuno's conception of liberalism, elaborated in essays such as La esencia del liberalismo in 1909, was one that sought to reconcile a great respect for individual freedom with a more interventionist state, bringing him to a position closer to social liberalism. In writing about the Church in 1932 during the second Spanish Republic, Unamuno urged the clergy to end their attacks on liberalism and instead embrace it as a way of rejuvenating the faith.

In addition to his writing, Unamuno played an important role in the intellectual life of Spain. He served as rector of the University of Salamanca for two periods: from 1900 to 1924 and 1930 to 1936, during a time of great social and political upheaval. During the 1910s and 1920s, he became one of the most passionate advocates of Spanish liberalism. Unamuno linked his liberalism with his hometown of Bilbao, which, through its commerce and connection with the civilized world, Unamuno believed had developed an individualism and independent outlook in stark contrast to the narrow-mindedness of Carlist traditionalism. When in 1912 José Canalejas was assassinated by an anarchist, he blamed it on the fact that Spain lacked a "true liberal democratic party" and in 1914 denounced the large property owners for their negligence and ignorance. Along with many other Spanish writers and intellectuals, such as Benito Pérez Galdós, he was an outspoken supporter of the Allied cause during the First World War despite Spain's official neutrality. Unamuno viewed the war as a crusade not just against the bellicose authoritarianism of the Germans, but against their sympathizers in Spain, and intensified his attacks on Alfonso XIII and the Spanish monarchy.

Unamuno was removed from his two university chairs by the dictator General Miguel Primo de Rivera in 1924, over the protests of other Spanish intellectuals. As a result of his vociferous criticisms of Primo de Rivera's dictatorship, he lived in exile until 1930, first banished to Fuerteventura, one of the Canary Islands; his house there is now a museum, as is his house in Salamanca. From Fuerteventura he escaped to France, as related in his book De Fuerteventura a Paris. After a year in Paris, Unamuno established himself in Hendaye, a border town in the French Basque Country, as close to Spain as he could get while remaining in France. Unamuno returned to Spain after the fall of General Primo de Rivera's dictatorship in 1930 and took up his rectorship again. It is said in Salamanca that the day he returned to the University, Unamuno began his lecture by saying "As we were saying yesterday..." (Decíamos ayer...) as Fray Luis de León had done in the same place in 1576, after four years of imprisonment by the Inquisition. It was as though he had not been absent at all. After the fall of Primo de Rivera's dictatorship, Spain embarked on its Second Republic. He was a candidate on the Republican/Socialist ticket and was elected, after which he led a large demonstration in the Plaza Mayor in which he raised the Republic's flag and declared its victory. He always was a moderate and refused all political and anticlerical extremisms. In a speech delivered on 28 November 1932, at the Madrid Ateneo, he protested against Azaña's extremist anti-clerical rulling: `Even the Inquisition was limited by certain legal guarantees. But now we have something worse: a police force which is grounded only on a general sense of panic and on the invention of non-existent dangers to cover up this over-stepping of the law.

In 1934, he wrote El hermano Juan o El mundo es teatro (Brother Juan or The World is a Theatre).

Unamuno's dislike for Manuel Azaña's ruling went so far as to tell a reporter who published his statement in El Adelanto in June of 1936 that President Manuel Azaña should commit suicide as a patriotic act". The Republican government had a serious problem with Unamuno’s statements, and on 22 August 1936, they decreed that Unamuno should once again be removed from his position as rector of the university. Moreover, the government removed his name from streets and replaced it with the name of Simón Bolívar.

In 1936 Unamuno had a public quarrel with the Nationalist general Millán Astray at the university in which he denounced both Astray—with whom he had had verbal battles in the 1920s—and elements of the rebel movement. (see § Confrontation with Millán Astray, below) Shortly afterwards, Unamuno was effectively removed for a second time from the rectorship of the University of Salamanca. A few days later he confided to Nikos Kazantzakis:

On 12 October 1936, the Spanish Civil War had been underway for just under three months; the celebration of Columbus Day had brought together a politically diverse crowd at the University of Salamanca, including Enrique Pla y Deniel, the Archbishop of Salamanca, and Carmen Polo Martínez-Valdés, the wife of Franco, Falangist General José Millán Astray and Unamuno himself.

Severiano Delgado, a historian and librarian at the University of Salamanca, asserts that Unamuno’s words were put in his mouth by Luis Portillo, in 1941, possibly with some help from George Orwell, in a piece in the literary magazine Horizon, entitled Unamuno’s Last Lecture. Portillo had not witnessed the event.

In 2018, the details of Unamuno's speech were disputed by the historian Severiano Delgado, who argued that the account in a 1941 article by Luis Gabriel Portillo (who was not present at Salamanca) in the British magazine Horizon may not have been an accurate representation of events.

As proof that the incident was nothing more than a crossroads of hard words, the photograph reproduced on the cover of his book shows Millán Astray and Miguel de Unamuno calmly saying goodbye in the presence of Bishop Plà, with no tension between them. The photo was discovered in 2018 in the National Library and was part of the chronicle of the act that the newspaper "The Advancement of Salamanca" published the following day, 13 October 1936.

The 2019 film While at War shows Unamuno (played by Karra Elejalde) between 18 July 1936 and his death.
