Jorge Mario Pedro Vargas Llosa, 1st Marquis of Vargas Llosa, more commonly known as Mario Vargas Llosa, is a Peruvian writer, journalist, essayist, college professor, and a former politician. Vargas Llosa is one of Latin America's most significant novelists and essayists, and one of the leading writers of his generation. Some critics consider him to have had a larger international impact and worldwide audience than any other writer of the Latin American Boom. In 2010 he won the Nobel Prize in Literature, "for his cartography of structures of power and his trenchant images of the individual's resistance, revolt, and defeat." He also won the 1967 Rómulo Gallegos Prize, the 1986 Prince of Asturias Award, the 1994 Miguel de Cervantes Prize, the 1995 Jerusalem Prize, the 2012 Carlos Fuentes International Prize, and the 2018 Pablo Neruda Order of Artistic and Cultural Merit.
Vargas Llosa rose to international fame in the 1960s with novels such as The Time of the Hero, The Green House, and the monumental Conversation in the Cathedral. He writes prolifically across an array of literary genres, including literary criticism and journalism.
