After the fall of the "Estado Novo", differences began to emerge on which political direction the country should take, including among the military. The revolution was mainly the result of the work of a group of young officers unified under the "Movimento das Forças Armadas" (MFA). Within this group, there were several different political views, among them those represented by Otelo Saraiva de Carvalho and considered to be the more radical wing of the movement and those represented by Ernesto Melo Antunes, considered to be the more moderate one.
