Victor Jara was born in 1932 in Lonquen, near Santiago, to two peasants, Manuel Jara and Amanda Martinez. His father was illiterate and encouraged his children to work from an early age to help the family survive, rather than attend school. By the age of 6, Jara was already working on the land. His father could not support the family on his earnings as a peasant at the Ruiz-Tagle estate, nor was he able to find stable work.

Early in his recording career, Jara showed a knack for antagonizing conservative Chileans, releasing a traditional comic song called "La beata" that depicted a religious woman with a crush on the priest to whom she goes for confession. The song was banned on radio stations and removed from record shops, but the controversy only added to Jara's reputation among young and progressive Chileans. More serious in the eyes of the Chilean right wing was Jara's growing identification with the socialist movement led by Salvador Allende. After visits to Cuba and the Soviet Union in the early 1960s, Jara had joined the Communist Party. The personal met the political in his songs about the poverty he had experienced firsthand.  Jara's songs spread outside Chile and were performed by American folk artists. His popularity was due not only to his songwriting skills but also to his exceptional power as a performer. He took a decisive turn toward political confrontation with his 1969 song "Preguntas por Puerto Montt" ("Questions About Puerto Montt"), which took direct aim at a government official who had ordered police to attack squatters in the town of Puerto Montt. The Chilean political situation deteriorated after the official was assassinated, and right-wing thugs beat up Jara on one occasion.  In 1970, Jara supported Allende, the Popular Unity coalition candidate for president, volunteering for political work and playing free concerts. He composed "Venceremos" ("We Will Triumph"), the theme song of Allende's Popular Unity movement, and welcomed Allende's election to the Chilean presidency in 1970. After the election, Jara continued to speak in support of Allende and played an important role in the new administration's efforts to reorient Chilean culture.  He and his wife, Joan Jara, were key participants in a cultural renaissance that swept Chile, organizing cultural events that supported the country's new socialist government. He set poems by Pablo Neruda to music and performed at a ceremony honoring him after Neruda received the Nobel Prize in Literature in 1972. Throughout rumblings of a right-wing coup, Jara held on to his teaching job at Chile's Technical University. His popular success during this time, as both a musician and a Communist, earned him a concert in Moscow. So successful was he that the Soviet Union tried to latch onto his popularity, claiming in their media that his vocal prowess was the result of surgery he had undergone while in Moscow.  Backed by the United States, which opposed Allende's socialist politics, the Chilean right wing staged a coup d'etat on September 11, 1973, resulting in the death of Allende and the installation of Augusto Pinochet as dictator. At the moment of the coup, Jara was on his way to the Technical University (today the Universidad de Santiago). That night, he slept at the university along with other teachers and students, and sang to raise morale. Answer this question using a quote from the following article:
