Neruda occupied many diplomatic positions in various countries during his lifetime and served a term as a Senator for the Chilean Communist Party. When President Gabriel González Videla outlawed communism in Chile in 1948, a warrant was issued for Neruda's arrest. Friends hid him for months in the basement of a house in the port city of Valparaíso; Neruda escaped through a mountain pass near Maihue Lake into Argentina. Years later, Neruda was a close advisor to Chile's 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.
