"Descamisada" is a Spanish term that literally translates to "without a shirt" or "shirtless." It became a significant term in Argentine history, particularly within the context of Peronism.
The term "descamisados" was popularized during the presidency of Juan Domingo Perón in Argentina. It was used to describe the working-class supporters of Perón, often those from humble backgrounds who worked in factories or manual labor and had limited means. The term carries a connotation of solidarity with the common people, particularly the labor class, and has been embraced by Peronists to represent a sense of unity and empowerment among the masses.
This song was performed by Nelly Omar, tango singer and personal friend of Evita. It was the most listened-to song in Argentina in 1951, and its lyrics exalt the Peronist woman, the descamisada, who fights every day for the good of the Nation.
