During times of domestic or foreign crisis, even most constitutional governments have conferred emergency powers on the chief executive, and in some notable cases this provided the opportunity for duly elected leaders to overthrow democracy and rule dictatorially thereafter. The proclamation of emergency rule, for example, was the beginning of the dictatorships of Hitler in Germany, Benito Mussolini in Italy, Kemal Atatürk in Turkey, Józef Piłsudṣki in Poland, and António de Oliveira Salazar in Portugal.
