The Francoist dictatorship stripped Negrín of his academic position and confiscated his estate. In July 1941 he was sentenced to the exorbitant fine of 100 million pesetas by the Special Court of the Law of Political Responsibilities, while in September 1941, the Special Court for the Repression of Freemasonry and Communism sentenced him to 30 years in prison (the maximum penalty, even though Negrin was neither a Mason nor a Communist). His father was imprisoned in Las Palmas for the mere fact of being his father, leaving prison in 1941 to die shortly thereafter in poverty after having been illegally expropriated of all his property.
