La Razón de mi vida (literal translation: "The Reason for My Life") is the autobiography of Eva Perón, First Lady of Argentina from 1946 until her death in 1952. Published in 1952 shortly before Eva Perón's death, it became one of the fastest selling books in Argentine history. Written in a conversational tone, it is largely a compilation of her speeches. Eva Perón shares her perspectives on feminism and the role of women in political life, labor rights, poverty, and, of course, Peronism, the political movement founded by her husband Juan Perón. In 1952, the year she died, the Congress of Argentina ordered the autobiography to be used as a textbook in the Argentine schools.
La Razón de mi Vida was a good seller overseas as well. However, initially, publication in the United States was refused. It has subsequently been published in the United States under the titles My Mission in Life and Evita by Evita.
