Excerpts from Books and Wikipedia
"In a sense, Franco's death on November 20, 1975, was merely the prelude. . . . Juan Carlos was considered a supporter of Franco's policies and had sworn an oath of allegiance to the fascist party (El Movimiento National). But he also held aspirations toward reform. The shift would not happen overnight, however, despite the opening up of political debate and party activity for the first time since the 1930s." [Furtado: 1001 Days]
