Unamuno, known as novelist, poet, essayist, and philosopher, was also passionately interested in the political development of Spain, and devoted much time to expressing his political ideas in thousands of articles for the Spanish and foreign press. Most of these were omitted from both editions of his complete works, and although several editions of articles have appeared in recent years, there is still a great deal of material which is still unavailable. The articles in this four-volume edition reflect both the persistence of Unamuno's campaign against politicians and royals and the complex picture of political, regional, and social tensions in post-bellum Spain. The original articles are in Spanish, the introduction, notes, and appendices in English.
