Miguel de Unamuno y Jugo was a prominent Spanish writer and philosopher, born in Bilbao on September 29, 1864, and passed away in Salamanca on December 31, 1936. He is renowned as a member of the Generation of '98, a group of Spanish intellectuals and philosophers.

Unamuno's work encompassed a wide range of literary genres, including novel, essay, theater, and poetry. He served as the rector of the University of Salamanca across three terms and was also a deputy of the Constituent Courts of the Second Republic. Despite initially supporting the military uprising that initiated the Spanish Civil War, he later publicly expressed regret for this support.

As one of the early existentialists, Unamuno was deeply concerned with the tension between intellect and emotion, faith and reason. His major philosophical work is The Tragic Sense of Life (1912). Among his most acclaimed novels are Mist (1914), Abel Sánchez (1917), and La tía Tula (1921).
