On July 15, 1945, at Pacaembu Stadium in São Paulo, Brazil, he read to 100,000 people in honor of Communist revolutionary leader Luís Carlos Prestes. During his lifetime, Neruda occupied many diplomatic posts and served a stint as a senator for the Chilean Communist Party. When a Conservative Chilean President González Videla outlawed communism in Chile in 1948, a warrant was issued for Neruda's arrest. Friends hid him for months in a house basement in the Chilean port of Valparaíso. Later, Neruda escaped into exile through a mountain pass near Maihue Lakeinto Argentina.
Years later, Neruda was a close collaborator to socialist President Salvador Allende. When Neruda returned to Chile after his Nobel Prize acceptance speech, Allende invited him to read at the Estadio Nacional before 70,000 people.
