The military-led coup can be described as the necessary means of bringing back democracy to Portugal, ending the unpopular Colonial War where thousands of Portuguese soldiers had been commissioned into military service, and replacing the authoritarianEstado Novo regime and its secret police which repressed elemental civil liberties and political freedoms. In addition, academics have published works theorizing that the efforts made by the MFA were not in the strict interest of the people of Portugal or its Overseas Provinces, since the movement was initiated not as an attempt to liberate Portugal from the authoritarian Estado Novo regime, but as an attempt of rebellion against the new Military Laws that were to be presented the next year. The Revolution and the whole movement were a way to work against Laws that would reduce military costs and would reformulate the whole Portuguese Military Branch. Younger military academy graduates resented a program introduced by Marcello Caetano whereby militia officers who completed a brief training program and had served in the overseas territories' defensive campaigns, could be commissioned at the same rank as military academy graduates. Caetano's Portuguese Government had begun the program on the advice of the Rhodesian Government, in order to increase the number of officials employed against the African insurgencies, and at the same time cut down military costs to alleviate an already overburdened government budget.
The systematic demolition of the old order was inaugurated by the MFA-led Junta de Salvação Nacional. As the pro-communist inspiration of the Junta was becoming increasingly evident, and far-left factions were taking the leading edge of the revolution, the process was halted by the coup of 25 November 1975. This period of social and political unrest which ensued after the 25 April military coup, is known as PREC, where leftist and rightist factions struggled for supremacy within the Portuguese society and political institutions. The moderates eventually won and this prevented post-revolutionary Portugal from becoming a communist or right wing-ruled regime. Finally, the Portuguese legislative election, 1976 took place on 25 April, exactly one year after the previous election, and two years after the Carnation Revolution. These elections could be said to be the definitive end of a period of revolution. Moderate democratic parties received most of the vote. Revolutionary achievements were not discarded, however. The constitution pledged the country to realize socialism. Furthermore, the constitution declared the extensive nationalizations and land seizures of 1975 irreversible. The military supported these commitments through a pact with the main political parties that guaranteed its guardian rights over the new democracy for four more years.
