Semi-presidential system with both an executive presidency and a separate head of government that leads the rest of the executive, who is appointed by the president and accountable to the legislature
Parliamentary republics with a ceremonial and non-executive president, where a separate head of government leads the executive and is dependent on the confidence of the legislature
Republics in which a combined head or directory of state and government is elected or nominated by the legislature
One-party states in which all other parties are either outlawed or only enjoy limited and controlled participation in elections.
While the Weimar Republic (1919–1933) and Finland (from 1919 to 2000) exemplified early semi-presidential systems, the term "semi-presidential" was first introduced in 1959 in an article by journalist Hubert Beuve-Méry,[5] and popularized by a 1978 work written by political scientist Maurice Duverger,[6] both of whom intended to describe the French Fifth Republic (established in 1958).[1][2][3][4]

The concept of a semi-presidential form of government, as used here, is defined only by the content of the constitution. A political regime is considered as semi-presidential if the constitution which established it, combines three elements: (1) the president of the republic is elected by universal suffrage, (2) he possesses quite considerable powers; (3) he has opposite him, however, a prime minister and ministers who possess executive and governmental power and can stay in office only if the parliament does not show its opposition to them.

The conventional analysis of government in democratic countries by political science and constitutional law starts from the traditional types of presidentialism and parliamentarism. There is, however, a general consensus that governments in the various countries work quite differently. This is why some authors have inserted distinctive features into their analytical approaches, at the same time maintaining the general dichotomy. Maurice Duverger, trying to explain the French Fifth Republic, found that this dichotomy was not adequate for this purpose. He therefore resorted to the concept of 'semi-presidential government': The characteristics of the concept are (Duverger 1974: 122, 1978: 28, 1980: 166): 1. the president of the republic is elected by universal suffrage, 2. he possesses quite considerable powers and 3. he has opposite him a prime minister who possesses executive and governmental powers and can stay in office only if parliament does not express its opposition to him.
