The group that has become known as the Generation of 1898 was marked by the destruction of Spain's fleet in Cuba by US gunboats in 1898, which provoked a cultural crisis in Spain. The "Disaster" of 1898 led established writers to seek practical political, economic, and social solutions in essays grouped under the literary heading of ''Regeneracionismo''. For a group of younger writers, among them Miguel de Unamuno, Pío Baroja, and José Martínez Ruiz (Azorín), the Disaster and its cultural repercussions inspired a deeper, more radical literary shift that affected both form and content. These writers, along with Ramón del Valle-Inclán, Antonio Machado, Ramiro de Maeztu, and Ángel Ganivet, came to be known as the Generation of '98.
