What is the Portuguese revolution?

The Portuguese Revolution (usually and also called 'The Cloves Revolution') is a turning point in Portuguese recent history that happened on April the 25th, 1974. Portugal was under Dictatorship from António de Oliveira Salazar (or just Salazar) for almost 50 years, and on that date the portuguese armed forces rebelled and sent tanks and troopers to the streets in Lisboa (the Portuguese capital) in order to free the people and provide democracy and individual freedom. Before the revolution, the portuguese people lived in a constant state of fear, mainly due to the portuguese secret police of the time (called PIDE), since all who weren't fit to live under the regime's motto of 'God, country and family' (homossexuals, communists, black people, gypsies, intelectuals, insurgents, dissidents, etc...) were exiled or sent to prisons in Africa (Tarrafal prison being one of the most feared), and would even 'disappear' or be found murdered. It is called 'The Cloves Revolution' because on that day, in Lisboa, cloves were being offered to everyone, including soldiers, and one of those soldiers took one and put it on his rifle, and afterwards all soldiers did the same.
