The coup resulted in a period of economic collapse and political instability, but received general support from the public in its aim of ending the Portuguese war effort in Africa. In the ex-colonies, officers suspected of sympathizing with the prior regime, even black officers, such as Captain Marcelino da Mata, were imprisoned and tortured, while African soldiers who had served in native Portuguese Army units were forced to petition for Portuguese citizenship or else face reprisals from their former enemies in Angola, Guinea, or Mozambique.
