Upon entering the government, Allende relinquished his congressional seat for Valparaíso, which he had won in 1937. Around that time, he wrote "La Realidad Médico Social de Chile" ("The social and medical reality of Chile"). After the Kristallnacht in Nazi Germany, Allende was one of 76 members of the Congress who sent a telegram to Adolf Hitler denouncing the persecution of Jews. Following President Aguirre Cerda's death in 1941, he was again elected deputy while the Popular Front was renamed Democratic Alliance.
