Semi-presidential system in the context of "Liberal democracy"

Representative democracy, also known as indirect democracy or electoral democracy, is a type of democracy where elected delegates represent a group of people, in contrast to direct democracy. Nearly all modern Western-style democracies function as some type of representative democracy: for example, the United Kingdom (a unitary parliamentary constitutional monarchy), Germany (a federal parliamentary republic), France (a unitary semi-presidential republic), and the United States (a federal presidential republic). Unlike liberal democracy, a representative democracy may have de facto multiparty and free and fair elections, but may not have a fully developed rule of law and additional individual and minority rights beyond the electoral sphere.

Representative democracy places power in the hands of representatives who are elected by the people. Political parties often become central to this form of democracy if electoral systems require or encourage voters to vote for political parties or for candidates associated with political parties (as opposed to voting for individual representatives). Some political theorists (including Robert Dahl, Gregory Houston, and Ian Liebenberg) have described representative democracy as polyarchy.

A head of state is the public persona of a sovereign state. The name given to the office of head of state depends on the country's form of government and any separation of powers; the powers of the office in each country range from being also the head of government to being little more than a ceremonial figurehead.

In a parliamentary system, such as India or the United Kingdom, the head of state usually has mostly ceremonial powers, with a separate head of government. However, in some parliamentary systems, like South Africa, there is an executive president that is both head of state and head of government. Likewise, in some parliamentary systems the head of state is not the head of government, but still has significant powers, for example Morocco. In contrast, a semi-presidential system, such as France, has both heads of state and government as the de facto leaders of the nation (in practice, they divide the leadership of the nation between themselves).

The Weimar Republic was a historical period of the German state from 9 November 1918 to 23 March 1933, during which it was a constitutional republic for the first time in history. The state was officially named the German Reich; it is also referred to, and unofficially proclaimed itself, as the German Republic. The period's informal name is derived from the city of Weimar,where the republic's constituent assembly took place. In English, the republic was usually simply called "Germany", with "Weimar Republic" (a term introduced by Adolf Hitler in 1929) not commonly used until the 1930s. The Weimar Republic had a semi-presidential system.

At the end of the First World War (1914–1918), the German Empire was economically and militarily exhausted and sued the Allies for peace. Awareness of an imminent defeat sparked the German revolution, the abdication of Kaiser Wilhelm II, the collapse of the Empire and the proclamation of the Weimar Republic. Hostilities in the war formally ceased with the Armistice of 11 November 1918.

The prime minister of Portugal (Portuguese: primeiro-ministro; pronounced [pɾiˈmɐjɾu miˈniʃtɾu]) is the head of government of Portugal. As head of government, the prime minister coordinates the actions of ministers, represents the Government of Portugal to the other bodies of state, is accountable to parliament and keeps the president informed. The prime minister can hold the role of head of government with the portfolio of one or more ministries. As Portugal is a semi-presidential parliamentary republic, the prime minister is the country's leading political figure and de facto chief executive.

There is no limit to the number of terms a person can serve as prime minister. The prime minister is appointed by the president following legislative elections, after having heard the parties represented in the parliament. Usually, the person named is the leader of the largest party in the previous election, but there have been exceptions over the years.

President is a common title for the head of state in most republics. Depending on the country, a president could be head of government, a ceremonial figurehead, or something between these two extremes.

The functions exercised by a president vary according to the form of government. In parliamentary republics, they are usually, but not always, limited to those of the head of state and are thus largely ceremonial. An exception to this would be presidential-parliamentary republics (e.g. Botswana and South Africa), the role of the president is more prominent, encompassing more of the functions of a head of government. In semi-presidential republics, the president has some discretionary powers like over foreign affairs, appointment of the head of government and defence, but they are not themselves head of government. A leader of a one-party state may also hold the position of president for ceremonial purposes or to maintain an official state position.
