The Carnation Revolution moved from military rupture to constituent politics and constitutional government.
The Estado Novo had governed Portugal as an authoritarian regime for decades while the country remained engaged in colonial wars in Africa.
On 25 April 1974 the Armed Forces Movement ended the dictatorship. The following period remained politically unstable and passed through six provisional governments rather than producing an immediate settled regime.
Free elections chose a Constituent Assembly in 1975. The Assembly approved the Constitution in April 1976; legislative and presidential elections followed, and the first constitutional government took office in July.
The revolutionary event opened the political field, but elections, a written constitution and institutions with independent authority converted the opening into a governable democratic order.
