José Carlos Mariátegui La Chira (14 June 1894 – 16 April 1930) was a Peruvian journalist, political philosopher, and activist. A prolific writer before his early death at age 35, he is considered one of the most influential Latin American socialists of the 20th century. Mariátegui's most famous work, Seven Interpretive Essays on Peruvian Reality (1928), is still widely read in South America. An avowed, self-taught Marxist, he insisted that a socialist revolution should evolve organically in Latin America on the basis of local conditions and practices, not the result of mechanically applying a European formula.
Mariátegui was born in Moquegua. His father, Francisco Javier Mariátegui Requejo, abandoned his family when José Carlos was young. To support her children, José Carlos' mother, María Amalia La Chira Ballejos, moved first to Lima, then to Huacho, where she had more relatives who helped her make a living. José Carlos had a brother and a sister: Julio César and Guillermina. In 1902, as a young schoolboy, he badly injured his left leg, and was moved to a hospital in Lima. Despite a four-year-long convalescence, his leg remained fragile and he was unable to continue his studies. The injury led to severe health problems later in life.
Though he hoped to become a Roman Catholic priest, at the age of fourteen he started working at a newspaper, first as an errand boy, then as a linotypist, then eventually as a writer. He worked in daily journalism for La Prensa and also for the magazine Mundo Limeño. In 1916, he left his first employer to join a new daily, El Tiempo, which had a more leftist orientation. Two years later he launched his own magazine, only to find that the owners of El Tiempo refused to print it. This led him to break with El Tiempo and launch a newspaper called La Razón, which became his first major venture in left wing journalism. In 1918, "nauseated by Creole politics," he wrote in an autobiographical note, "I turned resolutely toward socialism."
